jpmoldovan vs. jps7 G/60+30 D35 Queen's Gambit Exchange Variation

1.d4 d5 2.Nf3 Nf6 3.c4 e6 4.cxd5 exd5 5.Nc3 b6?!
The dubious tag may not be deserved but 5...b6 is, without question, the worst of 11 replies that I've seen here. [A better move order for those wanting to fianchetto the QB is 5...Be7 6.Bg5 h6 7.Bh4 0-0 8.Qc2 b6 9.e3 Bb7 as in, (with transposition) one of my 2006 KST losses to Mark Kernighan.]

6.Bg5 Bb7 7.e3 a6
[>=7...Be7 but, apparently, Black thought preventing Bb5+ or Qa4+ was necessary or worthwhile.]

8.Bd3
Diagram



8...Bd6N
Oh. This is the idea. He played a6 to stop Nb5 + Rc1. [>=8...Be7 which has been played 3 times; 8...Nbd7 which has been tried twice.]

9.0-0 0-0 10.Qb3?!
The attack against d5 doesn't get anywhere. [>=10.Ne5 , delaying ...Nbd7 or forcing Black to take-on doubled f-Ps, improves.]

10...Nbd7 11.Rad1
[>=11.Bf5+/= ]

11...Qc8?!
[This breaks the pin but why not just 11...c5= threat : ...c4?]

12.Bf5
Diagram



12...Ne4??
[This should have lost. Retracting with 12...Qd8+/= was best.]

13.Bh4??
[We missed 13.Nxe4 dxe4[] 14.Ne5 Bxe5[] 15.dxe5 Bc6[] 16.Qc2 Bb5 17.Qxe4+- ]

13...Nxc3 14.Qxc3 g6 15.Bh3 a5
This threatens to win an Exchange with 16...Ba6 16.Re1 Bb4... [... but >=15...f5= ]

16.Ne5
[>=16.Bg3 f5 (16...Ba6? 17.Qc6+/- Bxf1?? 18.Bxd7+- ) 17.Bxd6 cxd6 18.Qa3+/= ]

16...f5 17.Nc6
This ends-up being a waste of time. [>=17.f4 ]

17...Nf6 18.f3
If now 18...Ba6, then 19.Rf2 [18.Bxf6 Rxf6 19.g3!?= /\Ba6 20.Bg2 Bxf1 21.Bxd5+ Kg7 22.Rxf1+/= was an option, however.]

18...Qe8
[>=18...Qe6 /\ 19...Bxh2+ 20.Kxh2 Bxc6]

19.Ne5 Rc8
Diagram



20.g4?!
[>=20.Bg5 c5 21.Qb3 ]

20...Ba6
[20...Bxe5 21.dxe5 fxg4 was a good alternative; as it's doubtful I would've found 22.Bg2! (22.Bxg4?! Nxg4 23.fxg4 Qe6=/+ ) /\22...gxf3 23.Bxf3+/= ; 20...c5 21.Qb3 fxg4 was another.]

21.Rf2 Bb4?
[21...fxg4 22.Nxg4 Nxg4 23.Bxg4 Ra8= was correct.]

22.Qb3 fxg4?
After this, Black is lost. [22...Bb5+/- was best.]

23.fxg4+- Kg7?
Diagram

This makes things worse. [>=23...Be7 ]

24.Bxf6+?!
This brings the enemy K into the open... [... but >=24.g5 Nh5 25.Bxc8 Bxc8 26.a3 ]

24...Rxf6 25.Rxf6 Kxf6 26.g5+ Kxg5 27.Bxc8?!
[>=27.Qxd5 threatening mate in 3; as well as 28.Ng4+.]

27...Bxc8
[>=27...Bc4 28.Qc2 Qxc8 29.Qg2+ Kh6 ]

28.Qxd5 Be6
[>=28...Bd6 ]

29.Qg2+?
[29.Nf3+ Kh6 30.Qg5+ Kg7 31.Qe5+ was much stronger.]

29...Kh6 30.Rf1
[>=30.Qe4 ]

30...Bxa2
Black grabs a P to have something for the lost Exchange & the endgame but can he survive 'til then?

31.Qf3?!
Diagram

[31.Qe4 threatening 32.Ng4+; as well as 32.Qh4+ Kg7 33.Qf6+ Kg8 34.Nh6# was right.]

31...Be7??
[31...Qe7 ; & 31...Kg7 32.Qf6+ Kg8 33.Ng4 h5 were much better tries.]

32.d5
[>=32.Ng4+ Kg7 (32...Kg5 33.Qf4+ Kh5 34.Qh6+ Kxg4 35.Rf4# ) 33.Qe4 threatening 34.Qe5+ Bf6 35.Qxf6+ Kg8 36.Nh6#.]

32...Bg5
This loses a piece but there was no defense.

33.Nf7+ Kg7 34.Nxg5 Bc4
Unable to resign, my opponent plays to the bitter end.

35.Qf6+ Kh6 36.Nf7+ Kh5 37.Qg5#
Black checkmated Time left - Moldovan 17:08, Singh 60:52 Time used - Moldovan 61:22, Singh 17:08 Longest think by White - 11:33 for 20.g4?! Longest think by Black - 3:19 for 32...Bg5 Start - 12:38:45 p.m. End - 1:57 p.m. Game length - 1 hour, 19 minutes With this victory, I finished with a +5-1=2 record & a 7/9 score. 1-0
