Yes there is Bob....I don't know how you pull this stuff out of the air. Computers can and do attack, they use many "human" ideas in attacking. Here is one recent example. Rebel Century 4.0 - GM Loek van Wely 1. e4 e6 2. d4 d5 3. Nd2 Nc6 4. Ngf3 Nf6 5. e5 Nd7 6. Nb3 Be7 7. Bb5 Ncb8! Black can play a prophylactic move in a closed position. 8. 0-0 b6 9. Qe2 a5 10. Be3 Ba6 Janosevic - Suetin, Titovo 1966 and Nicevski - Sofrevski, Skopje 1967 continued with the immediate 10... 0-0. 11. a4 c6 12. Bxa6 Nxa6 13. Rfc1 White takes the initiative on the queenside. 13...0-0 14. c4 dxc4 15. Rxc4 Ndb8 16. Nbd2 Nb4 17. Ne4 N8a6 18. Nfd2 Nc7 19. Qg4! The computer changes its strategy ! It plans an attack on the kingside. 19...Kh8 20. Ra3 N4d5! The blockader in the centre assist in the defence of the kingside. 21. Bg5 f6 22. exf6 gxf6 23. Rh3! 23...Qe8 Avoids 23...fxg5?? 24. Qh5. 24. Qh4 Rf7 25. Bh6 White has a slight advantage, but his bishop allows little progress. Black gets time for a counter-attack. 25...b5 26. axb5 cxb5 27. Rc1 a4 28. Rg3!? Rebel keeps the pressure on the kingside. Better use of the mobility of white's pieces makes 28. Nc5! 28...a3?! More solid is 28...Rc8 29. Nf3 Bf8. 29. bxa3 Rxa3 30. Nf3!? The expected move is 30. Nb3, but Rebel further increases the pressure. 30...b4? Correct is 30...Bf8! followed by exchange. 31. Qh5! 31...Rxf3!? Desperation. Black has lost a pawn after 31...Bf8 32. Ne5! Re7 33. Nxf6! Nxf6 34. Qxe8 Ncxe8 (34...Rxe8 35. Nf7 mate) 35. Bxf8. A great variation is 31...Ra7 32. Ne5! fxe5 33. Ng5! Bxg5 34. Qxg5 (Threatens Bg7+) 34...Nb5. The opening of the c-file allows the combination 35. Qg8+! (Stronger than 35. Qxe5+ Rf6) 35...Qxg8 36. Rxg8+ Kxg8 37. Rc8+ Rf8 38. Rxf8 mate ! 32. gxf3! Bf8 33. Kh1! Re7 34. Rcg1 1-0 Rebel played incredibly strong.
