[...] 1.d4 d5 2.c4 e6 3.¤c3 ¤f6 4.¤f3 ¥e7 5.cxd5 I've played against the QGD exchange a fair number of times but I've never before seen this move order with 4. Nf3. It appears in the database but is much less popular than 4. cxd5. I decided to follow the normal development scheme. 5...exd5 6.g3 c6 7.¥g2 O-O 8.O-O ¦e8 9.¦e1 h6 This move may seem strange. I wanted to play Bf5 but was worried the bishop would be chased or traded by Nh4. h6 was to give the bishop a retreat square on the same diagonal. 10.¤e5 ¤bd7 11.¤xd7 ¥xd7 12.a3 £c8 13.b4 b5 14.e3 ¥h3 15.¤e2 ¥xg2 16.¢xg2 My idea here was that he's left with a bad bishop on c1 and I hoped maybe I could attack on the light squares since the defensive bishop is gone. 16...¤h7 17.¤g1 ¤f6 My idea had been to go Ng5, but that seemed like a dead end after Ng1 so I thought maybe rerouting like Nd7, Nb6, Nc4. But I think this and the following moves show a general planlessness. 18.f4 ¥d6 19.¤f3 ¤g4 20.¤e5 ¤f6 21.£c2 ¥xe5 22.dxe5 ¤e4 Right now it kind of seems like I have a good knight versus a bad bishop. My knight is outposted and can't really be kicked or traded. White's bishop is still undeveloped and doesn't seem to have much to do. 23.¥b2 £e6 24.¦f1 £g4 25.¦ae1 (25.£xc6 £e2+ 26.¢g1 £xb2) 25...¦ac8 26.£e2 £xe2+ 27.¦xe2 ¦a8 What I failed to appreciate here is that after the recapture on the second rank, white is now able to double against the c-pawn. Maybe better was Rc7, although it's unclear how I will play from there. In some ways Ra8 followed by a5 seems more active, although it would be better if I had chosen it with more conciousness of the consequences. 28.¦c1 a5 29.¦xc6 axb4 30.axb4 ¦a4 31.¦ec2 ¦xb4 32.¦c8 ¦xc8 33.¦xc8+ ¢h7 34.¥d4 I end up with a passed b-pawn but it's unclear how I will promote it. 34...¦c4 35.¦b8 b4 36.¦b5 ¤d2 37.¦xd5 b3 38.¦b5 ¦c2 39.¢h3 ¤c4 This just blunders the b-pawn. For some reason he didn't grab it. 40.f5 b2 41.e6 fxe6 42.fxe6 His king-side majority has produced a passed pawn on the 6th rank and I can't see how to promote my b-pawn. Here I was pretty sure I was losing. 42...¤d6 43.¦xb2 ¦xb2 44.¥xb2 ¢g8 45.¥a3 ¤c4 46.e7 ¢f7 47.¥c5 ¤e5 48.g4 g5 49.¢g3 ¤c6 50.e4 ¤xe7 51.¥xe7 ¢xe7 White is winning. 52.e5
52.¢f3 ¢e6 53.¢e3 ¢e5 54.¢d3 ¢e6 55.¢d4 ¢d6 56.e5+ ¢e6 57.¢e4 ¢e7 58.¢d5 ¢d7 59.e6+ ¢e7 60.¢e5 ¢e8 61.¢d6 ¢d8 62.e7+ ¢e8 63.¢e6 h5 64.gxh5 g4 65.h6 g3 66.h7 g2 67.h8=£#
52...¢e6 It should be a draw now. 53.h4
53.¢f3 ¢xe5 54.¢e3 ¢d5 55.¢f3 (55.¢d3 ¢e5 56.¢c4 ¢f4 57.¢d5 ¢xg4) 55...¢e5 56.¢e3 ¢d5 57.h3 ¢e5 58.¢f3 ¢d5
53...¢xe5 Still a draw if white captures on g5. 54.h5 (54.hxg5 hxg5 55.¢f3 ¢d5 56.¢e3 ¢e5 57.¢f3 ¢d5) 54...¢e4 I was just so glad I wasn't losing anymore that I hit the draw button without properly thinking. I'm actually totally winning here and I realized it only after I hit the draw button. He accepted so it ended here in a draw. The winning line is pretty straightforward although it is still possible to go wrong and allow a draw. 55.¢h3 ¢f4 56.¢h2 ¢xg4 57.¢h1 ¢xh5 58.¢h2 ¢h4 59.¢h1 g4 60.¢h2 g3+ 61.¢h1 ¢h3 62.¢g1 g2 63.¢f2 ¢h2
