3rd GRENKE Chess Classic 2015.2.4 Position after 17 moves. Black has played his opening a bit too loosely, and now has problems maintaining material equality. White can play 18.Bg5 with advantage (18…Nf4 19.BxN QxB 20.Bxb5), though Black can still put up stiff resistance.
Mickey Adams looked deeply into the position and found a clever tactical idea that greatly reduces the amount of work necessary to get a won game. Do you see it?
WHITE TO PLAY AND WIN!
3rd GRENKE Chess Classic 2015.2.4 Adams,Mi–Baramidze,D: 18.Rxa7! Rxa7 19.Bg5! Qg6 ( 19…Nf4 20.Qe3 Qg6 21.Bxf4 exf4 22.Qxa7 Bxh3 23.g3 should win easily enough for White ) 20.Qe3!! The whole point of White’s play. He threatens the win the Queen with Nh4 as well as the Rook on a7. Black must lose decisive material. The game continued 20…f6 21.Qxa7 fxg5 and now simply 22.Qxc7 (instead of 22.Nxe5, which was good enough to win) is the most convincing course to win.
