Nf3 Nc6 3. Bb5 a6 4. Ba4 Nf6 5. O-O b5 6. Bb3 Bc5 {I only play this variation occasionally. Gata has been doing some, I thought, none critical stuff against this variation. It looks inoccuous but it's not very pleasant.} 7. a4 Rb8 8. axb5 axb5 9. c3 d6 10. d4 Bb6 11. Be3 O-O (11... Bg4 12. Nbd2 exd4 (12... O-O 13. h3 Bh5 14. Qc2 {a longish game ensues.}) 13. cxd4 Nxd4 14. Bxd4 Bxd4 15. Bxf7+ Kxf7 {it isn't something you want.}) 12. Nbd2 h6 13. h3 Re8 14. Qc2 {Poisonous little move.} (14. Qe2 Bd7 15. Bc2 Nh7 16. Bd3 exd4 17. cxd4 Nb4 18. Bb1 Nf8 19. Rc1 Ra8 20. Ra3 c6 21. Rb3 Na6 22. Bd3 Nc7 23. Nf1 Nfe6 24. Ng3 c5 25. d5 Nf8 26. Rbc3 Ba5 27. Ra3 Bb4 28. Rxa8 Qxa8 29.

Nxg6 {1-0 Van den Doel,E (2440)-Lane,G (2420)/Wrexham WLS 1997}) 14... exd4 {Unsure what to do. "It doesn't seem that white is threatening much". Svidler came up with a "slightly ridiculous" idea.} (14... Bb7 {is stopped compared to Re1.} 15. d5 Bxe3 16. dxc6 Bxd2 17. cxb7 {Rook not en-prise on e1.}) 15. cxd4 Na5 (15... Bb7 {maybe better.}) 16. Ba2 Bb7 17. e5 (17. d5 Bxe3 18. fxe3 c6 {black holds quite comfortably.} 19. b4 Nc4 20. dxc6 Bxc6 21. Nxc4 Bxe4) 17... Nd5 { Normally this set up is very much in black's favour. I just assumed Nb4 and take the bishop. He played Bb1 and I'm very lucky I'm not just losing immediately.} 18. Bb1 {Just missed by Svidler in his calculations.} g6 19. Bxh6 Nc6 {I'm not saying I'm fine but it's trickier than it looks.} 20. exd6 {It seems that this is the move that throws away white's advantage.} (20. Qe4 dxe5 21. dxe5 Nf6 22. Qe1 (22. Qh4 {is the critical continuation.} Nxe5 23. Bg5 { when Svidler's immediate suggestion of} Nxf3+ {loses out of hand.} 24. Nxf3 Kg7 ) 22... Nd4) 20... Qxd6 21. Ne4 Qb4 22. Ba2 {My initial reaction is I must be lost now. Actually by this point I already saw it.} (22. Bd2 {may have been Kamsky's original idea.} Nxd4 23. Bxb4 Nxc2 24. Bxc2 Nxb4 (24... f5 {is even stronger.}) 25. Nf6+ Kh8 26. Nxe8 Nxc2 27. Rac1 Bxf3 28. Rxc2 (28. gxf3 Nd4) 28... Be4 29. Rxc7 Rxe8 30. Rxf7 {objectively black should be fine here. With his two bishops.}) 22... Nxd4 {My thought process. First of all there are no other moves.} 23. Nf6+ (23. Nxd4 {is a mistake as the moment I occupy the long diagonal I'm just perfectly fine here.} Qxd4 24. Nc3 Kh7 25. Rad1 Nb4 {and I think I might even be better.}) 23... Kh8 24. Nxd4 Nxf6 25. Nc6 {my first reaction is that I have to take.} Qh4 {Here I'm probably already better but it isn't obvious immediately.} (25... Bxc6 26. Qxc6 Qh4 {but the problem is this that white has this horribly strong move Be3 otherwise I think I'm fine.} 27. Be3 {I realised black is in a huge amount of trouble because my pieces are discoordinated and as soon as this bishop is exchanged away. All my potential initiative is gone. f7 is hanging, c7 will be hanging, I think I'm close to lost here. So I started looking at some romantic variations starting with Qh4.} ) 26. Nxb8 {There really isn't much white can do here. [Given that Svidler only needs a draw]} (26. Be3 Rxe3 27. fxe3 Re8 {For a single exchange I'm getting this horrible attack on the kingside and there really isn't much he can do. I definitely have a draw everywhere here and probably I'm already winning even.}) 26... Re2 $3 {Its something you see in Andersson games. Put on the cover of a book. Suddenly white is just completely lost.} (26... Be4 27. Qd2 Qg3 (27... Ng4 28. Bf4 {and the whole thing collapses because I'm running out of pieces.}) 28. Qg5 {was Svidler's initial idea.}) (26... Qg3 27. Nc6 Re2 {was Svidler's next idea which I think is actually quite decent. But before I started analysing this further I thought, why am I starting this owith Qg3? This is where it dawned on me what was happening. I was pacing outside where the food is.}) 27. Qc3 {He just didn't want to resign with Re2 on the board here.} (27. Qxe2 Qg3 28. Bd5 Bxd5 29. Bg7+ Kxg7 30. Qe4 Bxe4 31. Nc6 Qxg2#) 27... Rxf2 28. Nc6 Rxf1+ {and I'm just collecting the entire chess set. It's a very nice feeling to make a move like Re2 on the board. It really doesn't happen every day. It's a great feeling. It's something you don't really see in the modern game because you never have an opportunity to do anything like that. } 0-1
