1. c4 e5 2. g3 Sf6 3. Lg2 d5! 4. cxd5 Sxd5 5. Sf3 For me an interesting move. 5. Sc3 Sb6 6. Sf3 Sc6 7. O-O= 5... Sc6 6. O-O e4 6... Le7 7. d4 e4 8. Se5 f5 As played by Vassiliy Ivanchouk vs Alexey Shirov 2010 & Topalov vs Timman Jan 1999 7. Se1 Only field 7... De7 The Sumo ca lculated Bf5 for a very log time and came with this move, at first not good, but after my move just the opposite comes true 8. Db3?! Leaves e2 undefended , and an eventual d3 exd3 can't be met with Nxd3 as e2 would fall... . 8. d3 exd3 9. Sxd3 8... Sb6 9. Sc3 Le6 9... Sd4 10. Dd1 Lf5 11. Sc2 10. Dd1 f5 11. d3 O-O-O Chances are about even 12. Ld2 Unpins the Queen for capturing on e4 12. Le3? Sc4 12. Dc2 Sd4 13. Dd1 12. a3 g5 12... Sd5 Interesting move. 13. Dc1 Sd4 Even more interesting move.. . 14. Sc2!

Audacious move from a human against a digital opponent 14... Sxe2+ 14... Sxc3 15. Sxd4 (15. bxc3?? Sxe2+) (15. Lxc3?? Sxe2+) 15... Txd4 16. Lxc3 15. Sxe2 exd3 16. Sed4 And white has the far better play despite being the pawn down. 16... dxc2 17. Te1 Sf4 A surprising and curious move. 18. Sxe6 18. Lxf4 Txd4 19. Dxc2 with the threat Rxe6 & Qxc7 # 19... Td7 20. Te5 18... Sxe6 19. Dxc2 Sd4 20. Dc4 Dc5 Very neutralising move, white has to be very creative to keep the pressure now. 21. Tac1? 21. Da4 a6 22. Lg5 21... Dxc4 21... Sf3+ 22. Lxf3 Dxc4 23. Txc4 Txd2 24. Te8+ Kd7 25. Ta8= 22. Txc4 h6? 22... Sf3+ 23. Lxf3 Txd2= 23. Lf4 Sb5 23... Td7?? 24. Te8+ Td8 25. Txc7+ Kb8 26. Txd8# 23... c6 24. Le5 23... Ld6?? 24. Txd4 24. Tec1 Td7 24... c6 25. a4 (25. Lxc6?? Not playable 25... bxc6 26. Txc6+ Kb7) 25... Sd4= 25. a4 Sd6 26. Tc5 g6 26... b6 27. Tc6 27. Ld5! An very nice idea of mine. Prepares for Be6 27... Kb8 27... Se8 Bf8 counterattacks Rc5 28. Tb5! Sd6 29. Lxd6 Txd6 30. Lxb7+ Kd8 28. Le6 Tdh7 28... Te7?? 29. Lxd6 Txe6 (29... cxd6 30. Tc8#) 30. Lxc7+ Ka8 31. Te5 Txe5 32. Lxe5 Lg7 33. Lxg7 29. Le5 b6 30. Tc6 Probably not the best 30. Txc7 Txc7 31. Txc7 Kxc7 32. Lxh8 30... Lg7 Here I took my time, black is passive but offers a passive piece for an exchange... this might seem to work for him. 31. Lxd6 31. Txd6? Lxe5 (31... cxd6 32. Lxd6+ Kb7 33. Tc7+ Ka6 34. Lc4+ Ka5 (34... b5 35. Lc5 Lxb2 36. Lxb5+ Ka5 37. Tc6 Te7 38. Ta6#) 35. Txa7#) 32. Td2 31... cxd6 32. b4 a cool mov e, d6 is isolated and wxeak, will surely fall, no need to go for an immediate Rxd6. also better then b3 cause of Be5 f4 Bd4+ follwed by Bc5 which is not possible with b4 (instead of b3) 32... Td8 33. Tc7 d5?? An actual bad move ! Likely just behind the computers horizon. 34. Lxd5 Txd5 35. Tc8+ Kb7 36. T1c7+ Ka6 37. Ta8 Td1+ 38. Kg2 Tg1+ 39. Kxg1 b5 40. Taxa7+ Kb6 41. a5# 1-0 [Stefan Timmermans]
