A couple of days ago I reported on the successful performance of two French programs, Chess Wizard and Zchess, in the Aubervilliers rapid chess tournament. As this particular position may have been overlooked, and as I believe that it is worth analysing with different chess software, I'll try to bring it up again. White: GM Sekatchev, Black: Zchess 1.2: 1. e4 c5 2. Nf3 Nc6 3. Bb5 g6 4. Bxc6 dxc6 5. d3 Bg7 6. h3 Qb6 7. Nc3 Qb4 8. O-O Bxc3 9. a3 Qa5 10. bxc3 Qxc3 11. Rb1 Qa5 12. Bb2 f6 13. e5 f5 14. e6 Nf6 15. Qc1 b6 16. Re1 O-O 17. Qh6 c4 18. dxc4 Bxe6 19. Rxe6 Rf7 20. Ng5 * 1-0 on move 8, Black (Zchess 1.2) played 8...Bxc3. Of the tested programs, the only one not yielding to the temptation was Zarkov 5 playing 8...Nf6, not bothering to capture the Knight, which is, of course, a good move. Other programs, among them Crafty 16.0, according to Zchess's author Franck Zibi, tend to play the same bad move, 8...Bxc3. More info, with comments by Franck 1. e4 c5 2. Nf3 Nc6 3. Bb5 g6 4. Bxc6 dxc6 5. d3 Bg7 6. h3 Qb6 7. Nc3 Qb4 8. O-OBxc3 9. a3 Qa5 10. bxc3 Qxc3 11. Rb1 Qa5 12. Bb2 f6 13. e5 f5 14. e6 Nf6 15. Qc1b6 16. Re1 O-O 17. Qh6 c4 18. dxc4 Bxe6 19. Rxe6 Rf7 20. Ng5 *Zibi, can be found at http://www.forum64.com/. Some tested programs are (AMD K6-2/300): ZChess 1.2 Bxc3 ?? 11 +0.80 WChess 2000 Bxc3 ?? 11 +0.88 Crafty 16.0 Bxc3 ?? 12 +0.13 Chess Genius 6 Bxc3 ?? 8 -0.06 Fritz 5.0 Bxc3 ?? 11 -0.25 Zarkov 5 Nf6 ! :-) 6 -0.19 What does your program play in this position? Bob, you said that you could not reproduce 8...Bxc3. Could you retry it on your Quad? Others? Regards, Djordje
