Nf3 d5 4. Nc3 Bb4 5. cxd5 exd5 6. Bg5 Nbd7 7. Rc1 c6 8. e3 (8. a3 Bd6 {is a different variation.}) 8... Qa5 9. Bd3 Ne4 {Following a game between Gelfand-Jakovenko from 2009. For some reason these ideas are not as popular for Black as they should be, it shows you that there is still a lot of unexplored territory in the Ragozin.} 10. O-O Nxg5 11. Nxg5 Nf6 12. Qc2 h6 13. Nf3 Bd6 14. Ne5 {The novelty of the game, the aforementioned game had continued with 14.h3. Either way it looks like Black should be ok.} Ng4 $5 { Trying to get rid of the knight on e5, as currently f4 is impossible.} 15. Nf3 Nf6 16. h3 {And now we are back into Gelfando-Jakovenko.} O-O 17. Ne5 a6 (17... c5 $2 18. Nb5 Bxe5 19. dxe5 Nd7 20. f4 $16 {Gelfand-Jakovenko, 2009.}) 18. f4 c5 {A desirable break that was not really possible the previous move.} 19. g4 $5 {Lunging forward!} cxd4 20. exd4 Be6 21. Qb3 (21. g5 hxg5 22. fxg5 Bxe5 23. dxe5 Nh5 $15 {doesn't really net White any advantage.}) 21... b5 22. f5 Qb6 23. Nf3 Bc8 {One would think taht White is doing ok here, but the deeper I inspect the position the more troubles I find with it. He is over extended on the kingside and the only compensationt is his pressure on d5. However, as soon as this pawn is taken, the diagonal will dangerously open for the bishop.} 24. Kg2 (24. Nxd5 Nxd5 25. Be4 $1 (25. Qxd5 Bb7 26. Qb3 Rae8 {loses quickly.}) 25... Nc7 $1 26. Rc6 Qb8 27. Rxd6 Ne8 28. Bxa8 (28. Rc6 Qg3+ {is not possible.}) 28... Qxd6 {with lots of compensation for the pawn.}) 24... Bb7 25. Na4 Qa7 26. Nc5 Rac8 {White cannot hope to keep this knight on c5. But trading on b7 would mean opposite colored bishops with White's king very exposed on the h2-b8 diagonal.} 27. a4 $6 Bxc5 28. dxc5 d4 {Now White's position simply collapses. The power of the bishop on b7 is too much.} 29. axb5 axb5 30. Qxb5 Bc6 31. Qb6 Qd7 32. Kg1 Rfe8 33. Rce1 Rxe1 34. Nxe1 Re8 35. Ng2 Nd5 (35... Bxg2 36. Kxg2 Qd5+ 37. Kg1 Re3 $19) 36. Qb3 Ne3 37. Nxe3 dxe3 38. Qc4 Qc7 {Good enough. The following sequence is forced and Black is simply up a piece.} 39. Qf4 Qxf4 40. Rxf4 e2 41. Bxe2 Rxe2 42. Rb4 Rg2+ 43. Kf1 Rc2 0-1
