Earlier this year, FM Steve Stoyko gave a talk on the King's Indian Attack (generally with 1.e4 c5 2.Nf3 e6 3.d3), using his games for illustration. The theme of the talk was that every piece has its place in the KIA "tabia" or formation...except the dark-squared Bishop. But as soon as you know where that Bishop should go, you usually have a decisive edge. It was remarkable to note how often the Bishop enters the game with powerful effect, just as Steve said.
You can play over the games from the talk online (with my notes mostly) or download the PGN. The puzzle above is taken from the first game, Stoyko-Farrell, with White to play and win. Notice that the dark-squared Bishop still has not developed.
Steve will lecture on the Exchange Variation of the Queen's Gambit Declined this Thursday from 7:00 p.m.-8:00 p.m. at the Kenilworth Chess Club. The cost of the lecture is $5 and it is open to all. At 8:30 p.m. play begins for Rounds 3 and 4 (the last two rounds) of the Kenilworth Classic Game-30 tournament.
