Ken Smith, a FIDE Master/USCF Senior Master who also finished fourth in the 1981 World Series of Poker, declared that until a chess player at least becomes a strong "A" player (one level below Expert) his first name should be tactics, his middle name should be tactics and his last name should be tactics: Smith felt that a player must improve his tactical acuity to a certain base level in order to most efficiently beat lower rated players and at least be able to compete with Experts and Masters; if a player's tactics are weak then even if he knows a lot of opening theory and can build a good position it will be difficult for him to convert that position into a win.
I enjoy solving chess tactics; recently, I looked at some tactical puzzles at Chessbase.com and thought that I had solved the first position but then saw that my proposed move order was not listed as the correct solution. I sent an email to the Chessbase.com editor about this and he amended the listed solution to include my move order as well. Here is a link to the tactic:
I have not made USCF Master yet but I guess now I can say that I made a "Master Move"!
