BND match vs Sanjay Sharma

Sharma,S (939) - Prong,C (1798)
Brand New Day Cafe, 03.02.2006
Queen's Gambit Declined: Tarrasch Defense [D32]

1.d4 d5 2.c4 e6 3.Nc3 c5 4.cxd5 exd5 5.Nf3 Nc6 6.Bf4
I hadn't studied up on this particular line of the Tarrasch Defense, but I managed to play the next book move anyhow.
6...Nf6 7.e3 Be7 8.Bd3 0-0 9.0-0 Re8 10.Rc1 a6 11.a4
This move created a potentially big hole on b3, if the queen ever deserted its protection of that square.
11...Bg4 12.Be2 dxc5
seems to be a more effective method of protecting the weakness on d4.
12...Rc8 13.Qd2
This removes the protection on the b3 square. dxc5 would have been preferable. 13...Na5
Now the c6 bishop heads for the hole on b3.
14.Ne5?? Nb3
White did not recognize the potential knight fork on b3, so black take immediate advantage.
15.Qd1 Bxe2
Clearly betted than Nxc1 Bxg4
16.Qxe2 cxd4
I was looking for potential ideas that would win more material than just the exchange. This intermezzo requires the response Sanjay played and still allows black to gain the exchange. Additionally, black opens the c-file for his rook.
17.exd4 Nxc1 18.Rxc1 Qb6 19.Rd1 Bd6 20.Qf3 Qb3
Qxb2 is probably a better option.
21.Rb1 Bb4
The b2 pawn is pinned, and thus would not be able to capture on c3 should black play Rxc3 or Bxc3. The bishop give black one extra attacker so that the queen cannot recapture on c3.
22.Bd2 Bxc3 23.Bxc3 Ne4??
This allows Qxf7. Better was Qxa4.
24.Rc1?? f6 25.Ng4 Nxc3 26.bxc3 Rxc3!
A beautiful mating combination!

27.Qxc3 Qxc3 28.Rxc3 Re1# 0-1
