US Amateur Team Playoff (2), 20.03.2004
[Hummel]



1.e4 e6 2.d4 d5 3.Nc3 Bb4 4.e5 c5 5.a3 Bxc3+ 6.bxc3 Ne7 7.Nf3 Nbc6 8.Bd3 Qa5 9.Bd2 c4 10.Bf1 Bd7 11.g3 f6 12.exf6 gxf6 13.Bh3 0-0-0 14.0-0
All standard stuff so far. Normally in this position, black plays the immediate 14...e5. But in this position I felt it would be hard for white to do anything with the center locked, whereas black has a clear plan of expanding on the kingside. Hence I decided on a new move which prepares to open lines to white's king before going ahead with the central break.

14...Rdg8N
This move puts the rook on the half-open file and frees d8 for my knight to defend e6.

15.Qe1 Nd8
In the next few moves, I now plan to play ...Ng6, and ...h7-h5-h4.

16.Nh4?
This move gets white into trouble. [ 16.Bh6 , frusturating black's plan to expand is the move I expected. White will follow with 17.Qe3 and an interesting game will result.]

16...Ng6-/+ 17.Kh1
This sad move is not what white wants to do, but there is nothing better. The position resulting after [ 17.Nxg6 hxg6 18.Bg2 Rh7 is strategically hopeless for white. Black will have all the time in the world to mate white on the kingside, and white will never have a chance to make a threat for the rest of the game.]

17...Nxh4 18.gxh4 Qa4!
Threatening ...Qxc2 and preparing ...e5.

19.Qd1 e5 20.Bg2 Bg4 21.f3 Bf5 22.dxe5 fxe5 23.Bg5 Qc6
Black has an obvious advantage in this position, though white can still try to sit tight and defend with something like 24.Qd2. But knowing that passive defense may be doomed to failure, white decides to lash out with what should be the losing move.

24.f4? h6!-+
Now black wins by force.

25.fxe5
I expected [ 25.Bxd8 which I would have met with 25...Rxg2 26.Kxg2 Rxd8 with a winning attack. White can no longer defend now that the f-pawn is not no f3. For example: 27.fxe5 d4+ 28.Kf2 Bh3 29.Rg1 Rf8+ 30.Ke1 d3 31.cxd3 Qb6 32.d4 Qb2-+ Even though it's not hard to see that black has an easy win after this, I still expected white to play this way. At least there's some chance for black to go wrong in this line, but the refutation of 25.fxe5 just seemed so obvious. Still, 25.fxe5 is quite possibly the best move.]

25...Qg6
Now white must give up the exchange.

26.Rxf5 Qxf5 27.Bf3!
The best chance. [ 27.Bxd8 Qxe5 28.Ba5 Rxg2 29.Kxg2 Rg8+ 30.Kf2 Qxh2+ 31.Ke3 Qe5+ 32.Kf2 Qg3+ 33.Ke2 Re8+-+ is too easy for black.]

27...Qxe5 28.Bd2
Having played very well so far, I can finish my opponent off by playing the simple 28...Ne6 29.Be1 Rd8 with a winning material advantage. But for some reason I was afraid of some ghost lines where white puts his bishop on g3, and my king is in an awkward position on the h3-c8 diagonal. Hence I decide on a seemingly safe move that wastes time and lets white back into the game.

28...Kb8?? 29.Be1 Ka8 30.Bxd5 Rg6 31.Qf3 Rf6 32.Qg2 Rhf8 33.Bg3 Qxc3 34.Rb1
Black may still be better, but white has a lot of counterplay with his strong two bishops. With both sides in time trouble, I needed only a draw to assure our team's victory. So I just decided to sit tight and make it clear that white couldn't make progress.

34...Nc6 35.Qe4 Qd2 36.Qxc4 Rd8 37.Bg2 Qd7 38.a4 Rf5 39.Qe4 Rc5 40.Bf2 Ra5 41.Qe3 h5 42.Qb3 Rf8 43.Be1 Raf5 44.Bg3 Qf7 45.Qc3 Qd7 46.Qa3 Re8 47.Qc3 Ref8 48.Qb2 Re8 49.Qa3 Rc8 50.c4 Rf7 51.c5 Re8 52.a5 a6 53.Qb3 Rc8 54.Bd6 Rg7 55.Bh3 Qe8 56.Qf3 Rd8 57.Bg2 Qf7 58.Qc3?? Qd7??
Yes, we both missed 58...Rxg2. Yes, that would have won of the spot. Strange things happen.

59.Rf1 Rf7 60.Re1 Re8 61.Rb1 Rg8 62.Bd5?? Qf5!
This time I don't miss my chance.

63.Rd1 Qxd5+! 64.Rxd5 Rf1#!!
Mate!! 0-1
