Oh, yes, Bob! I botched it up pretty well I must say, for which I apologise. The actual game was: 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 * and Zchess 1.2 played first the atrocious 7...Qb4, followed by the gruesome 8...Bxc3. These two moves, but primarily the Bxc3 could be tested by other programs. Franck Zibi did test some programs, and only Zarkov 5 refrained from capturing the Knight and played the sober Nf6! Thanks for pointing out the error, Djordje
