Back to Basics Preparing the Classic Bishop Sacrifice Know your goal and be persistent—but not rigid—in pursuing it. By GM Lev Alburt The winner of this month’s award, Andrew Liu, provided us with a well-written story, complete with diagrams, subtitles, and summary. (My own comments will be in italics). Writes Andrew: Dear GM Alburt, My name is Andrew Liu and I just turned 11. I’m from San Diego, California. This game was very exciting for me because I won with the classic bishop sacrifice. My chess coach Mario Amodeo introduced me to this fascinating pattern a few months ago using your 1996 column in Chess Life. I learned a lot from this game after analyzing it with my coach and on my computer (Houdini chess engine). I hope it will be an encouragement to other young players.

Bd3 The game started with the Queen’s Gambit/Slav Exchange. I had many bishop “sac” opportunities before with this opening. I was very focused on prepar44 Chess Life — July 2012 ing for the bishop sac from the opening. That’s why I didn’t bring my dark square bishop out of the pawn chain before playing 6. e3. This bishop supports the later Ng5+ move. Bringing it out early would risk getting traded off. Although my plan worked this time, I should have been more flexible with my plan and not bank everything on the sac. As you will see later on, Black can easily prevent the sac if he is aware of the plan. I wasted a tempo in 7. Bb5+. I was playing “hope” chess trying to force Black to trade his dark square bishop with my knight. Once Mr. Carnall played 7. ... Bd7, I pulled my valuable bishop back to its rightful diagonal eying h7. I’m sure glad I kept the bishop. 8. ... Qc7 9. Bd2 0-0 10. 0-0 a6 11. Re1 Bb5 (??—L.A.) 12.

Here, I could’ve taken his intruding bishop with my knight and bishop and won a pawn. In fact, 12. Nxb5 would have won a full piece. 12. ... Bd7 (12.

I call this strategy “removing the guard.” 14. ... dxe4 15. Nxe4 Nxe4 16. Bxe4 Bc6 rsn-+-trk+ +pwq-+pzpp p+lvlp+-+ +-+-+-+-+-zPL+-+ zP-+-+N+-zP-vL-zPPzP tR-+QtR-mK- After 16. ... Bc6 My plan to remove the knight worked well when Black took my pawn. I abruptly took with my knight, gaining a direct attack on my target: the f6-knight. I had a blast of excitement as I chopped his knight with my bishop after he accepted the trade. I have successfully removed the guard! I got a feeling my bishop sac would catch him off guard. Ways to prevent my sac are putting a bishop on e7 or playing ... h7-h6, both will make the later Ng5+ harder. Still, 16. ... Be7 (or 16. ... h6) 17. Rc1 favors White, who’s better developed. Stage 2: The Classic Bishop Sacrifice 17. Bxh7+! (punch 1) The Classic Bishop Sacrifice. After calculating the risks and rewards including Black’s Bxh2+, I went for the sac! My coach Mario said that you don’t have to calculate all the way before doing the sac. I was very hopeful because the calculation seemed to give me the advantage up to 19. Qg4. You may be surprised. I have only failed once in all the bishop’s sacs I’ve ever done. I have “sac’ed” many times over the board and online. Also, the only two people that have bishop uschess.org
