[Vaja, Ashish]

1.e4 e6 2.d4 d5 3.Nc3 Bb4 4.e5 f5 5.Nge2 Ne7 6.a3 Bxc3+ 7.bxc3 Ng6 8.h4 h6 9.h5 Ne7 10.Rh3

This is a thematic plan in these positions, if you want to see come classics that use this plan check out Euwe's games vs. the Winawer. [10.g4 This is an interesting move, which I did consider in the game, but in light of the following variation I declined. 10...c5 11.g5 hxg5 12.Bxg5 Nbc6 13.h6 (13.Rg1 Qa5 14.Qd3 Rh7) 13...gxh6 14.Bf6 Rh7 15.Qd2 cxd4 16.Nxd4 Qb6 I think that white is still much better, but this is not as clean as it should be. Right out of the opening my opponent allowed me to gain space from the opening and fix the k-side pawns. ] 10...c5 11.Rg3 Rg8 12.Nf4 Qa5 13.Bd2 [13.a4] 13...c4 14.Rh3? Blindeadsun you are correct, this is the mistake, although the idea itself is correct I failed to see what blacks threat was here. Now that the tension on d4 is gone, c3 can easily be covered by the rook on g3. Makogonov tells us to find the worse placed piece and improve it, which is the bishop on d2. White had to continue: [14.a4! Nbc6 15.Bc1 Bd7 16.Ba3 0-0-0 17.Be2 Kb8 18.Qb1 Nc8 19.Kf1 Black is already struggling to find useful moves and white will continue to improve his position. ] 14...Nbc6? [14...Qa4! This is the idea that my opponent missed, the a3 and c3 pawns are potential targets all of a sudden. This is such a deep move, but after looking over more Winawer games it seems to be thematic. Being my first game in the Winawer (except for when I was much weaker) I did not even consider this idea. 15.g4 Nbc6 16.Rg3 Bd7 17.Bh3 0-0-0 The problem is now obvious the bishop on d2 can only observe the other pieces struggle to prove an advantage. 18.Be3 (18.gxf5 exf5 19.e6 Be8 Black is freeing himself. ) 18...Rdf8 19.g5 a6 This is the whole point, now black has the plan to play Na7-b5 and whites task is not so simple. ] 15.Be2? [15.a4!] 15...Bd7? [15...Qa4!] 16.g4? This was my last chance. [16.a4!] 16...0-0-0? [16...Qa4] 17.Rg3 [17.a4? g5 18.hxg6 Nxg6] 17...Rdf8? [17...Qa4!] 18.g5 Andy, the position is already lost at this point, Nd8 is not really a blunder considering how bad the position is for black. 18...hxg5 19.Rxg5 After this it is straightforaward. 19...Nd8 20.Qb1 Nf7 21.Rg3 Re8 22.Qb4 Qc7 23.0-0-0 Nc6 24.Qb2 Nh8 25.Rdg1 Nxe5 The position is already close to lost even though black is not down material yet, white is about to cash in, Emory makes a last attemt to complicate matters. 26.dxe5 Qxe5 27.Bf3 Nf7 28.Rg6 Nh8 Offers Draw 29.R6g3 Nf7 30.Qb4 Qc7 31.Rxg7 a5 32.Qb2 Rxg7 33.Rxg7 Ne5 34.Be2 Qd8 35.h6 Qh4 36.Qb6 Qxh6 37.Nh5 Resigns 1-0

  1. How is black LOST after 18.g5?

    To me this is FAR from lost. White has no material, nothing super clear, what am I missing that is so good for white? Seems as if white has an obvious slight advantage due to his more active pieces but how will white convert that into a win?

  2. There is no stopping white just crasing though on the kingside or queenside. Do you see a particular line that holds for black? During the game my main line for him was 18...hg 19. Rxg5 a6 (After the game I learned about Qa4, but here it wont work since: Be3, Kd2, if a6-Na7 then Qb1 going to b4) At this point the position is a nightmare for black all his pieces are passive and has to constantly defend g7. White hit both sides of the board now by improving on the queenside with something like: 18...hg 19. Rxg5 a6 20. Qb1 Rf7 (if N@c6 any where then Qb4) 21. Qb2 Kc7 22. Rb1 b6 as you can see black is totally tied down and no harmony at all and something like Be3 then Kd2 will be totally winning. It is a positional squeeze.

  3. Ok ok, I must have misunderstood you, with perfect play black should probably be lost, I thought you meant "losing" in eval terms like white had some clear win. I'm too lazy to set up a board but if I remember correctly Kb8 or even Nb8 were much tougher defences where black has some complicated but interesting defenses, I don't see the plan behind a6. I would just say white has a clear edge, totally winning might be too far at this stage.

    Also in your line with 14...Qa4 did you consider 19.Bg2 instead of 19.e6? The pawn on e5 will be held forever so maybe white shouldn't be in a rush to push it so soon since it may just become a target. Again, I don't have a board up but Bg2 seems to be the critical test. Maybe when I set it up I'll be able to find a defense for black...

  4. Yup Bg2 and white is clearly better. I suppose he should be careful for sacs to open the center on his king, but doesn't look like black has anything concrete and white should just be up a clear pawn and still have his positional advantage with the additional two passed pawns in the center.
