Here is one game that shows deep tactics. It's fairly straightforward if you consider the first sacrifice. Even though it's a +twenty ply (+ thirty if you add the mate) combination. It's from Nunn's 'Understanding Chess move by move.' [Event "?"] [Site "?"] [Date "?"] [Round "-"] [White "Nunn"] [Black "Nataf"] [Result "0-1"] 1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 e5 5. Nb5 d6 6. c4 Be7 7. N1c3 a6 8. Na3 f5 9. Bd3 f4 10. g3 Nf6 11. gxf4 exf4 12. Bxf4 O-O 13. Bg3 Ng4 14. Be2 Nxf2 15. Qd5+ Kh8 16. Bxf2 Nb4 17. Qh5 Rxf2 18. Kxf2 Bh4+ 19. Kg2 g6 20. Qf3 Qg5+ 21. Kf1 Bh3+ 22. Qxh3 Rf8+ 23. Bf3 Qe3 24. Qxh4 Nd3 25. Nd5 Qxf3+ 26. Kg1 Nf2 27. Kf1 Qxh1+ 28. Ke2 Qxa1 0-1 [D]r1bq1rk1/1p2b1pp/p1np4/8/2P1P1n1/N1NB2B1/PP3P1P/R2QK2R w KQ - 0 14 White must play 14. O-O [D]r1bq1rk1/1p2b1pp/p1np4/8/2P1P1n1/N1N3B1/PP2BP1P/R2QK2R b KQ - 0 14 Best move 14... Nxf2 [D]r1bq1r1k/1p2b1pp/p1np4/3Q4/2P1P3/N1N3B1/PP2Bn1P/R3K2R w KQ - 0 16 Only move 16. Rf1 [D]r1bq1r1k/1p2b1pp/p1np4/3Q4/2P1P3/N1N5/PP2BB1P/R3K2R b KQ - 0 16 Best move 16... Nb4/Rxf2 [D]r1bq1r1k/1p2b1pp/p2p4/7Q/1nP1P3/N1N5/PP2BB1P/R3K2R b KQ - 0 17 Best move 17... Rxf2 Most of the rest of blacks moves are only moves. It would be interesting to know when different programs begin to have a clue that black is winning. Black misses a mate in seven but it's still an impressive game. MvH Dan Andersson
