Professional Tennis is Plagued by Match Fixing

In The Secret World of Tennis Match Gambling, Tomas Rios details rampant match fixing in the professional ranks. Rios explains why corruption is so pervasive in professional tennis:

Tennis is perfectly suited--in every way--for match fixing.

Tennis is the third-most bet upon sport in the world and, between the ATP and the Women's Tennis Association, there are 126 tournaments making up this year's tour. The sheer volume of betting and matches makes spotting suspicious activity virtually impossible in all but the most obvious and reckless cases.

Then there's the sport's inherent vulnerability to "spot fixing." European sportsbooks allow bettors to wager on not just matches, but sets, games, and even individual points. A corrupt player could easily throw a handful of points over the course of a match and not even the keenest observer would be able to spot it.

Of course, a player needs motivation to go corrupt. Tennis does a fine job of making sure players have the best motivation of all.

The "motivation" is that it costs well over $100,000 to play on the ATP or WTA tours when one includes travel costs and the cost of a full-time coach. While the top-10 players make more than $1,000,000 per year and thus have much less incentive to cheat, most tennis professionals can make more money--and guaranteed money at that--by fixing matches than they can make by trying to win prizes honestly.

A 2014 study by Ryan Rodenberg and Elihu Feustel titled "Forensic Sports Analytics: Detecting and Predicting Match-Fixing in Tennis" used betting market analysis and predictive tennis models to determine that it was likely that at least one percent of first round tennis matches over a span of more than two years were fixed. That works out to an average of 23 matches per year--and that does not include the sets, games and points that may have been thrown in "spot fixing" scams.

Rios cites a specific match from 2007 pitting the fourth ranked player in the world versus a player who barely cracked the top 100. The wagering on that match reached a fever pitch--10 times the average--and the match ended with the fourth ranked player conceding the match after claiming that he was injured. The ATP investigated the situation for over a year but could not prove any wrongdoing. Nevertheless, within the tennis community it is widely believed that the match was fixed--and that type of corruption casts a pall on the entire sport.

Emory Tate Will Long Be Remembered For Slashing Attacks and Spirited Conversation

I was shocked and saddened to find out this morning that International Master Emory Tate passed away yesterday while participating in a California chess tournament. Tate was originally from Indiana and he was a fixture on the Midwest chess scene for many years, winning six Indiana state championships in addition to claiming five Armed Forces championships and a host of other tournament wins. Tate did not receive the International Master title until he was almost 50, a testament to his hard work and persistence.

Of course, for years before Tate became an IM he was a threat to anyone he faced, even a former World Championship Candidate like Grandmaster Leonid Yudasin, who was the eighth ranked player in the world in January 1991. No article about Tate is complete without including this brilliant and beautiful game from the 1997 U.S. Masters:

FM Emory Tate vs. GM Leonid Yudasin

1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 6. Bc4 e6 7. Bb3 Nbd7 8. Qe2 Nc5 9. g4 b5 10. g5 Nfd7 11. Bd5 Bb7 12. Bxb7 Nxb7 13. a4 bxa4 14. Rxa4 Nbc5 15. Ra3 Qb6 16. O-O Be7 17. Kh1 O-O 18. b4 Na4 19. Nf5 exf5 20. Nd5 Qd8 21. exf5 Re8 22. Qh5 Nab6 23. Rh3 Nf8 24. f6 Nxd5 25. fxg7 Kxg7 26. Bb2+ Kg8 27. g6 Bf6 28. gxf7+ Kh8 29. Rg1 Re1 30. Rxe1 Bxb2 31. Re8 Nf6 32. Rxd8 Rxd8 33. Qh6 Ne4 34. Qh4 Nf6 35. Rg3 N8d7 36. Qh6 1-0

Tate justifiably loved to show that game to anyone who was interested. I personally watched Tate rattle off those moves from memory on several occasions. His descriptions of the lines he analyzed during the game were mesmerizing and entertaining. It is important to note that when Tate showed the game it did not feel like he was showing off; Tate loved chess, loved to talk about chess, loved to analyze chess and that passion shined through when he discussed this game, so what an observer experienced was Tate's joy and the wonders of chess, as opposed to someone bragging about beating a top GM.

I faced Tate six times in over the board play from 1997-2008, scoring two draws and four losses. In the first round of the Oberlin (Ohio) Open on 4/29/2000, I missed a chance to defeat Tate (who candidly admitted after the game that he had stood worse) and he finished the game in his typical style:

David Friedman (2096) vs. Emory Tate (2443)

Shortly after I played this game, my friend NM Mark Kalafatas told me, "There are NO better tactical players in the country than Emory Tate. He has a genuine and very rare gift in that regard and has beaten most of the best players in the country at one time or another. I think he is the Earnie Shavers of chess...He (Shavers) gave Ali a good fight and was a terribly powerful puncher that could knock out anyone with a single blow."

Tate loved to talk about a variety of subjects and he was willing and eager to analyze chess games with anyone at any time, regardless of a person's rating or status. I enjoyed the time that I spent with him at various tournaments over the years and regret that I will never again have the opportunity to watch him analyze his win against Yudasin.

IM Emory Tate will be long remembered and dearly missed by anyone who was fortunate enough to cross his path.

Djokovic Once Again Bests Federer in a Grand Slam Final

A significant amount of the coverage leading up to the U.S. Open Final focused on Roger Federer as an ageless tennis deity who has remade his game and even developed a new shot (which--with his characteristic humblebrag modesty--he calls "SABR," meaning Sneak Attack by Roger) that supposedly is an unstoppable weapon. That is all well and good, except that this coverage has been rendered largely meaningless by a story that should be the headline grabber but likely will not capture as much attention as all of the praise that has been heaped on Federer: the real story is two-fold, namely (1) Novak Djokovic defeated Federer in the U.S. Open Final in four sets and (2) Djokovic is clearly the best player in the world, even if he has not named a shot after himself or convinced writers that it is their sworn duty to wax poetic about his every breath, move and statement.

Much of the mainstream media coverage of tennis defies logical analysis. It does not make sense to assert that (1) Federer is as good as he has ever been and (2) that he is the greatest player of all-time while relentlessly ignoring Federer's struggles versus Rafael Nadal and Djokovic. If Federer is as good as he has ever been and if Federer truly established himself years ago as the greatest player of all-time then he should still be winning Grand Slams. Otherwise, it is only logical to assert--at a minimum--that even if Federer achieved greatest of all-time status at some point in the distant past he has since been supplanted by Nadal and Djokovic. Logically and conceptually it simply does not compute to say that Federer is the greatest of all-time and that he has developed a new shot that makes him better than ever but that the successes of Nadal and Djokovic are irrelevant in terms of the greatest player of all-time debate--and this does not even take into account the fact that a very good case could be made that Bjorn Borg is better than all three of them.

There is no question that Federer is very durable. That durability has enabled him to amass some impressive career numbers, including his record-setting 17 Grand Slam singles titles. However, Federer has appeared in 66 Grand Slam events and his .258 Grand Slam winning percentage is not even close to the record Grand Slam winning percentage posted by Borg (.407). Borg never lost in the first round of a Grand Slam, he lost in the second round just once and he made it to at least the quarterfinals in 20 of his 27 appearances (.741). Federer has lost in the first round of a Grand Slam six times, he has lost in the second round once and he has advanced to the quarterfinals in 46 of his 66 appearances (.697).

Federer's head to head struggles versus Nadal are well documented, with the tally currently standing at 23-10 in Nadal's favor, including 9-2 in Grand Slam matches and 6-2 in Grand Slam Finals. Nadal has not been nearly as durable as Federer, though Nadal has been durable enough to win at least one Grand Slam for 10 straight years (2005-14), breaking the mark of eight set by Borg and later matched by Pete Sampras and Federer. Nadal is tied with Sampras for second on the all-time list with 14 Grand Slam singles titles but Nadal's Grand Slam winning percentage (.326) is much better than Federer's or Sampras' (.269). Injuries have limited Nadal at various points in his career and especially since the French Open in 2014 (Nadal's last Grand Slam singles title) but Federer has suffered an even longer drought, with his last Grand Slam winning coming at Wimbledon in 2012 (Federer's only Grand Slam title since 2010).

The Djokovic-Federer head to head rivalry is now tied at 21-21, but Djokovic enjoys the edge in Grand Slam matches (8-6) and Grand Slam Finals (3-1). Federer won five of their first six head to head encounters but Djokovic has captured 20 of the next 36, including each of the past three times that they have met in a Grand Slam Final. Djokovic has won 10 Grand Slam titles in 44 appearances (.227) while losing twice in the first round and twice in the second round and reaching the quarterfinals 34 times (.773, a percentage even better than Borg's).

If Federer had defeated Djokovic in the U.S. Open Final then this would have been cited as yet another piece of evidence that Federer is indisputably the greatest player of all-time--but Djokovic's win against Federer seemingly does not in the slightest way dent Federer's claim to that title. When Nadal beat Federer like a drum, Federer's fans made the excuse that Nadal was a clay court specialist. Now, Djokovic is beating Federer on hard courts (U.S. Open), on grass courts (Wimbledon) and on clay (2012 French Open, 2015 Italian Open) but nothing can seem to loosen Federer's supposedly secure grip on the mythical greatest of all-time title.

If Federer were washed up and just playing out the string then one could make the case that at least some of his losses to Nadal and Djokovic should not count when determining the pecking order among these three players--but the reality is that Federer, Nadal and Djokovic have been in or reasonably close to their primes from late 2008 to the present. During that time, Federer has been ranked number one in the world for 65 weeks, Nadal has been ranked number one in the world for 141 weeks and Djokovic has been ranked number one in the world for 164 weeks. During that same time span, Federer has won five Grand Slam singles titles, Nadal has won nine Grand Slam singles titles and Djokovic has won nine Grand Slam singles titles. It is difficult to make a reasonable case that Federer is better than Nadal and, considering Djokovic's recent success (three Grand Slam wins in 2015 while appearing in each of the four Grand Slam Finals), it is at least arguable syllogistically that Djokovic is better than Federer as well; after all, if Federer is as good as ever and Djokovic is beating Federer on multiple surfaces than Djokovic is not only better than Federer now but he is better than Federer has ever been.

Just once, it would be refreshing to see a Federer supporter in the media write an article making a point something on the order of "As Federer advanced through this tournament I was reminded of why I like his game so much and why he is so highly regarded but after Federer lost to (Djokovic or Nadal) I was also reminded that, while Federer excels in wiping out the lesser lights, he has never established clear superiority over the other two great players of his time." Federer's SABR turns into a butter knife when he faces Nadal or Djokovic and it is difficult to picture Federer having the necessary mental or physical energy to contend with the relentless Borg in his prime.

ESPN Whacks Patriots in Knees With Regurgitated and Unsubstantiated Allegations

After NFL Commissioner Roger Goodell's high-priced lawyers got caught with their legal briefs down and were chastised by federal court Judge Richard Berman for their role in helping Goodell impose his own brand of what Judge Berman termed "industrial justice," it was inevitable and predictable that Goodell would put the mafia-style hit (metaphorically speaking) on the Patriots (which is not to suggest that he ordered or told ESPN to do anything but merely that ESPN--like any loyal capo--knows what the big boss wants done and takes care of it as quickly as possible). So, ESPN--the official propaganda mouthpiece of the NFL--just issued a supposedly bombshell-filled investigative report detailing how Goodell's bumbling of the alleged ball deflation matter is actually a "make up call" for Goodell's handling of the so-called "Spygate" scandal.

One thing that "Spygate" has in common with the alleged ball deflation scandal is that, in both instances, ESPN misreported the facts. During "Spygate," ESPN repeated a never verified--and since debunked--allegation that the New England Patriots illegally recorded the St. Louis Rams' walkthrough prior to Super Bowl XXXVI. Not content to misreport the facts during the immediate aftermath of "Spygate," ESPN resurrected that debunked story this year and had to issue a public--albeit buried--apology. Fast forward to this year's alleged ball deflation scandal, when ESPN--specifically Chris Mortensen--incorrectly reported that 11 of New England's 12 footballs were measured at 2 p.s.i. below the minimum permitted levels at halftime of the 2015 AFC Championship Game. ESPN's motto should be "Never Let the Facts Get in the Way of a Story That Can Garner Ratings and Revenue."

The new ESPN article contains no new facts but plenty of salacious allegations and quotes from unnamed sources. It would be shocking if it does not contain factual errors, since that is a staple of ESPN reporting, particularly concerning the Patriots. The gist of the story is that a lot of teams that have lost to the Patriots suspect deeply in their hearts that the Patriots cheat in some way. These teams cannot actually prove this but they are pretty sure it is true. Supposedly, Goodell saved the NFL from doom by burying the truth about the Patriots' cheating but promising that if anyone ever cheats again then he will throw the book at them. Thus, after Mortensen made his erroneous report about the Patriots' alleged ball deflation, Goodell jumped in quickly with his "make up call" for supposedly not dealing with "Spygate" harshly enough.

Since Goodell, via ESPN, is determined to retry "Spygate" in the court of public opinion after getting trounced in an actual court regarding the alleged ball deflation scandal, it is worth revisiting the truth about what actually did--and did not--happen during "Spygate." YourTeamCheats is an excellent guide and I will quote from some of that site's research:

The announced reason that the Patriots were punished was for filming their 2007 regular season game against the Jets from a sideline location instead of from an approved filming location (e.g. a press or media box). The actual reason was because they were told to do something by Goodell and didn't do it...

The Patriots were not punished for filming the Jets defensive signals, as that has never been forbidden by the NFL. As of 2006, however, where you film the game and signals is limited to approved locations. Coincidentally, the Jets had done nearly the exact same thing a year earlier but were not punished, even a little bit, by NFL commissioner and former Jets public relations intern Roger Goodell...

Filming your opponents' signals is--and always has been--completely legal, even today. After a league memo to all clubs in 2006, however, you can't do it from a location where the team could potentially use it during the same game.

As Coach Bill Belichick noted in 2015, 80,000 people can see his team's defensive signals: millions more if a TV camera pans by them. The signals are not meant to be hidden, just as in baseball a third-base coach's signals are not meant to be hidden. They should, however, be properly encrypted, but that is the signaling team's responsibility.

Every single NFL team films every single game they play from multiple angles. As they do this, are they supposed to locate and black out the one part of the stadium where the defensive coach is? Should it be a roaming dot if he moves? Obviously not, because the sidelines are just another part of the larger football field and game.

Spygate was:
  • 10% about where they were filming from
  • 90% about Belichick stupidly thumbing his nose at Goodell's new rule, and
  • 0% about what was being filmed
It should have been called WrongLocationgate or F*ckYouRogergate, because there was absolutely no element of spying involved.

Judge Berman Deflates Roger Goodell's Overinflated Perception of his Power

The deflated football "scandal" is a lot of nonsense that was probably incited by people jealous of the New England Patriots' success (either people in the NFL office who used to work for rival teams and/or people who are currently affiliated with rival NFL teams) and clearly fueled by the sloppy reporting/reckless commentary of "journalists" like Bob Kravitz, Mike Wilbon and Chris Mortensen, each of whom has played fast and loose with the facts while issuing broad, sweeping pronouncements that they are not qualified to make concerning issues of sport, fairness and the law (Peter King also filed a report that was subsequently debunked, but at least he had the good sense and grace to apologize, unlike the defiant Mortensen and the bizarrely proud Kravitz, who listed his self-promoting, bombastic coverage of the story as his "drops the mic" moment on his self-evaluation of his past year's work).

Federal District Court Judge Richard Berman just inserted some common sense--and sound legal principles--into the situation with a scathing 40 page ruling that eviscerates NFL Commissioner Roger Goodell for the heavy-handed, sloppy and unfair way that Goodell and his cronies conducted the investigation and punishment of New England quarterback Tom Brady. After spending millions of dollars, the NFL could not come up with one piece of hard (or even circumstantial) evidence proving that the footballs in question were illegally deflated, let alone that Brady had anything to do with the alleged illegal deflation: the scientific analysis of the footballs in question is, at best, inconclusive, and there is no proof that Brady had anything to do with deflating the footballs even if it is true that the footballs were deliberately deflated in a manner that violates NFL rules. Nevertheless, Goodell suspended Brady for four games (under a bizarre theory equating ball deflation with illegal steroid use, a notion that an incredulous Judge Berman summarily dismissed) and media members dragged Brady's name through the mud, saying that Brady should accept the suspension (or at most bargain for a slight reduction) to just close the matter. I am sure that if someone punished Kravitz, Wilbon or Mortensen on the basis of no evidence those guys would just roll over and accept it.

Instead, Brady took the NFL to court and pounded Goodell even more soundly than Brady's Patriots defeated the Indianapolis Colts in the AFC Championship Game. Judge Berman expressed unconcealed disdain for the NFL's "independent" investigation (the mocking quotes are Judge Berman's) and chastised the league for refusing to grant Brady the opportunity to cross-examine his accusers and see relevant evidence. So, contrary to the incessant media bleating that we have been hearing for months, it is actually the NFL--not Brady--who obstructed the fair investigation of this matter; you can take the word of Kravitz, Wilbon and Mortensen about this point of law or you can take the word of a federal judge who comprehensively reviewed the matter and actually knows how a legal investigation is supposed to work. Goodell also repeatedly moved the goal posts on Brady, changing what Brady was being charged with doing and what basis was being used to determine Brady's punishment. Judge Berman waded through the NFL's sloppy investigation and bizarre, draconian discipline and voided Goodell's four game suspension of Brady. Keep in mind that federal courts rarely overturn an arbitrator's decision but in this case it is so obvious that Goodell neither conducted a competent investigation nor fairly served as the arbitrator of his own ruling that Judge Berman had little choice but to decide the case in Brady's favor.

The NFL has already announced that it will appeal the verdict. Maybe the league will achieve victory at the Circuit Court level, though that seems doubtful since the league's lawyers just lost in the District Court that they selected for this battle (they filed suit in New York because they felt that they would receive more sympathy in that jurisdiction than in any other one). The NFL's refusal to admit wrongdoing, accept defeat and move on brings to mind Grand Moff Tarkin's mocking dismissal of the idea that the Death Star should be evacuated right before Luke Skywalker blew it to smithereens: "Evacuate? In our moment of triumph? I think you overestimate their chances."

This saga could potentially drag on for years as it works its way through the federal court system but anyone who enjoys football, respects the legal process and values journalistic integrity hopes that when all is said and done we will no longer have to hear from Goodell, his "independent" investigator Ted Wells, Kravitz (whose most recent column about the Judge Berman ruling betrays a complete inability and/or unwillingness to understand what Judge Berman decided), Wilbon, Mortensen and everyone else who has added much heat but little light to the matter at hand.

The Sport of Chess

The title of this article may seem contradictory or even absurd to some people but over 100 countries officially recognize chess as a sport, as does the International Olympic Committee. John Foley recently offered an eloquent explanation of why chess is a sport. Foley cited 10 reasons that chess is a sport and he urged his home country England to join the 24 out of 28 European countries that classify chess as a sport. Here are some quotes from Foley about each of those 10 reasons:

1) Competitive: ...Chess involves a relentless struggle against one's opponent. There is probably no sporting activity in which two people are locked in a competitive struggle of such intensity for such a sustained period of time. One lapse of concentration and suddenly a good position is transformed into a losing one...

2) Well established: The world championship has been organised since 1886 and our national federation was founded in 1904. Chess competitions are organised at every level: schools, universities, counties, cities, leagues, junior, senior, European, World, etc...

3) Physical fitness: Peak mental condition requires being in good physical condition. Players need to concentrate totally for up to seven hours. As the stress and tension builds up, blood pressure, pulse and respiration rates all increase. Contenders for the world championships have nutritionists and fitness coaches.

4) Behaviour code: Players are penalised for poor sportsmanship e.g. for refusing to shake hands with their opponent. Potential cheating is taken seriously...There is an anti-doping policy.

5) Olympic Recognition: Chess has been recognised as a sport by the International Olympic Committee since 2000. It was an event at the Asian Games in 2006 in Doha and again in Guangzhou in 2010. It is also being considered for inclusion in the Pan-American Games...

6) European Recognition: Chess is recognised as a sport in 24 out of 28 member states of the European Union...

7) Global game: Chess is played around the world irrespective of age, race, gender, income or language...

8) Mental component: All sports have a mental component. Ultimately competitive sports may be construed as strategy games differing only in their physical manifestation. Commentators are prone to similes such as: curling = chess on ice; bowls = chess on grass; snooker = chess with balls, and so on.

9) National accolade: World chess champions have won their national Sportsman of the Year competition including Magnus Carlsen (Norway), Vishy Anand (India) and Veselin Topalov (Bulgaria).

10) Player ranking system. The player ranking system was developed for chess in 1960 and has been adopted by many other sports including American football, baseball, basketball, hockey, korfball, rugby and golf. Football and cricket use a related formula.

Foley concludes, "Chess has health benefits. There is an emerging awareness of the effectiveness of chess in delaying the onset of Alzheimers. Chess promotes social integration as players travel to a venue and interacting socially. Chess presents a welcome social activity to many children who are on the autistic spectrum. Many Aspergers children find chess opens up for them a whole new world which conventional sport does not. For many adults, chess provides them with meaning in their lives."

IM Justin Sarkar Obtains Third GM Norm

In 2009, I wrote about International Master Justin Sarkar's "perfect game." IM Sarkar has been pursuing the Grandmaster title for several years, capturing his first GM norm in the 2006 Marshall Chess Club Championship and earning his second GM norm in the 2013 U.S. Masters Championship. IM Sarkar obtained his third and final required GM norm in the May 2015 UTB Grandmaster Norm tournament, so he will receive the GM title once he pushes his FIDE rating to the 2500 level.

IM Sarkar wrote an article for Chess Life Online about his excellent performance in the May 2015 UTB Grandmaster Norm tournament and that article included his round four win against GM Holden Hernandez. In the fifth round, IM Sarkar polished off IM Joshua Ruiz from the black side of the Caro-Kann. The Ruiz game is interesting not only because of how smoothly IM Sarkar defeated IM Ruiz without allowing any counterplay but also because of some thoughts that IM Sarkar shared with me about the etiquette of making draw offers during tournament play. As a strong club player (2100+ USCF), I have noticed that in local events (and even in some larger regional events), players either do not know the correct draw offer etiquette or else they disregard it. The proper method for a player to offer a draw is to make a move, say "I offer a draw" and then hit the clock, enabling the opponent to consider the draw offer undisturbed on his own time. If the opponent declines the draw offer, it is inappropriate to offer a draw again unless you have subsequently declined a draw offer or unless the position has substantially changed since you made your first offer. It is unacceptable to offer a draw (or communicate with your opponent in any way, other than to say "I resign") when your opponent's clock is running and it is unacceptable to harass your opponent with repeated draw offers.

IM Sarkar submitted these comments about his game versus IM Ruiz:

Here's my round 5 game as black against IM Joshua Ruiz. It was played just after my fine win round 4 against GM Holden Hernandez. As hinted in the (CLO) article, I felt it was also a "convincing win" by me.

On move 23 (after playing 23.Rh3), he offered me a draw. This might have bothered me slightly, because I knew that my position was better, possibly significantly better as I correctly realized (and I think there was no extenuating factor to justify the offer, such as me being significantly down on time). However, since it was made just after making his move (and just that one time), I didn't really have a problem nor read much into it.  

As for draw offers, unfortunately there have been players who violate the basic etiquette involved in offering, especially by offering during my thinking time (even a professional GM did that to me in the last year, from a position where I was much better but not yet clearly winning, while taking a long time to decide on my move). While I prefer to be shown proper respect in when to offer me a draw, especially by lower rated opponents (such as, not offering in a situation where I'm likely to decline), by far most important to me is for proper protocol to be followed. "Proper respect" in this context means different things depending on rating level: lower rated players should generally not offer draws unless they have a better, risk-free type of position (but are content with a draw) or they have a significant advantage on the clock and they consider their position at least acceptable, while equally rated players and higher rated players should not offer draws from a clearly worse position, except perhaps if they enjoy a big time advantage.

Regarding proper protocol, generally, offering in the midst of my thinking time is a no-no (except, maybe in a situation where I'm virtually certain to accept, such as when it's clear the opponent is the one pressing me), as is offering more than once before receiving one (except, again, maybe in a situation where I'm almost certain to accept the second one, such as my position being clearly worse or me being on the worse side of a drawn ending). As for the draw offer timing, if on a given move I'm taking a "long think" (as with that GM), getting impatient for me to move is not an excuse for offering a draw while I'm thinking. It's very distracting (except, maybe if I'm thinking for a long time on how to try and defend a worse or lost position; however such offers have usually come when my position is equal or better, including by lower rated players). Offering during their thinking time is also improper but not as bad, as I always have the option to just say nothing and let their clock run (or simply tell them to first make a move), while having the option to consider after their move on that turn.

IM Sarkar adds that 10.Nxh5 is "dubious, though a consistent follow-up, and his 9.Be2 was a slightly dubious novelty, maybe decided upon at the board."
