This position is alredy very rare, the Lichess masters DB has only one game with the postion after dxc5, G Kenworthy - C Baker from 1999! According to Stockfish black already has a clear advantage, that was not at all obvious to me during the game, though I felt black hadn't done anything to deserve being worse , Nd7 is very important black needs to keep the bishop on the d8-h4 diagonal and the knight belongs on c5 where it both stops a white Ne4 and can take the bishop about to appear on d3. } 10. Nf3 Nxc5 11. Bd3? { After this the computer evaluation jumps significantly in blacks favour, SF thinks white should play much more cirumspect starting with Nd4 or Kb1. During the game both I and some of the rest of team were much more worried by whites caveman approach than the computer is. } 11... Bd7 { Played after a very long think, I couldn't decide between b5, f5 or the textmove, and pleasingly Stockfish has the same quandry same for the first 5 minutes or so it fluctuates between the same 3 moves, after which Qc7 appears as an option as well, I've no idea why. In any case the evaluation suggests all 4 moves are of roughly equal value, so I should just have picked one much quicket than I did. The main reason I chose Bd7 was to put connect blacks rooks and put something between my queen and the white rook. } 12. h4 f5 13. exf6 { In the game against IM Chris Baker mentioned above he played Qg3 on f5 (the position was not identical but very similar) and black quickly took over the intiative on the queenside. However, SF thinks it's the lesser evil, if you believe the evaluation black is now winning (+2). That's much easier to see in hindsight than it was at the time.! } 13... Nxd3+ { No more worrying about sacs on h7! } 14. Rxd3 Bxf6 15. Ng5?! Qb6! { My first instinct was to play h6 but I wasn't completely certain he couldn't play Ne6 , so once I noticed that he can't play Qh5 after the textmove it's the obvious move to me though my oppenent said after the game that it surprised him. } 16. Qh5? { Hmmm he's not supposed to be able to play that, have I overlooked something? Well I have no choice so lets see. } 16... h6 17. Qg6? { Time for a double check, have I missed something? Nope, not that I can see. } (17. Nf3) 17... Bxg5+ 18. hxg5 Be8 19. Nxd5 Bxg6 20. Nxb6 axb6 { Not sure why he didn't resign here, especially as in our quick chat after the game he said he needed to get away for a meeting, in any case we carried on a bit. } 21. Rd6 Rxf2 22. gxh6 gxh6 23. Rxh6 Kg7 24. Rh3 Rxc2+ 25. Kd1 Rxa2 26. Rd7+ Kg8 { not Kf8??? Rh8 mate! or Kf6??, Rf3+ with a probable draw due to Rxg6 tricks if the black king ever goes to the g file. } 27. Rd8+ Kf7 28. Rd7+ Ke8 29. Rd2 Rxd2+ 30. Kxd2 Rxb2+ { 0-1 Black wins. } 0-1
