My students this week are seeing a position from a game played by Irina Krush. Advanced students are seeing the entire game, and many get to try their hand at playing the attack that she used to finish the game. I found the game on a video put on YouTube to advertise Krushing Attacks by U.S.. Women's Champion Irina Krush, sold by OnlineChessLessons.net. I bought the video.
I have been going through Krush's games looking for positions from which to create chess problems for a contest that will take place during the 2015 Washington State Elementary Chess Championship, for which I am the Event Director. Irina Krush will there. She will run a chess camp the day before the championship, and play a simul. During the championship, she will offer game analysis all day. Then she will play a a blindfold vote chess game against youth players at a reception that evening.
Krush,Irina -- Liete [E12]
New York Open, 1996
1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.Qc2 b6 5.Nf3
Krush points out in the video that she could have played 5.e4 here.
5...Bb7 6.Bg5 0–0 7.e3 d6 8.Bd3 Bxc3+ 9.bxc3 h6 10.Bh4 Nbd7 11.0–0 e5 12.Bf5 Qe8 13.Nd2 g6 14.Bd3
14.Bh3? g5 15.Bg3 g4 would be terrible for White.
14...Kg7 15.Rae1 Nh5 16.f4 f5 17.h3 e4
Krush suggests that 17...Qf7 is probably better.
18.Be2 Qe6 19.Kh2 Kh8 20.g4 Nhf6 21.gxf5 gxf5 22.Rg1 Rg8 23.Nb3 a5
23...c5 was worth considering.
24.d5 Qf7 25.Nd4 Nh7
25...Ne8 26.Ne6 Nc5 27.Qd1 Nxe6 28.Bh5 Qd7 29.Rxg8+ Kxg8 30.dxe6 Qxe6 31.Rg1++-.
White to move
This is the position that I present to all students. Some of them have found the correct move with a guidance.
Krush threatens both Bh5 and Qd4. Her move is clearly the strongest in the position.
27...Nxe6 28.dxe6 Qxe6 29.Qd4+.
28.Bh5 Qd7 29.Qd4+ Kh7 30.Rxg8 Nfxe6
30...Kxg8 Some of my students have faltered playing from this position. 31.Rg1+ Kh7 32.Nxf8+ Rxf8 33.Bg6+ Kg8+-.
