[Moldovan & Houdini 1.5a]

board 2 G/75+5 (delay) D06 Queen's Gambit Marshall's Defense

1.Nf3 d5
[I expected 1...c5 aiming at an Accelerated Dragon.]

2.d4 Nf6 3.c4 e6 4.cxd5 Nxd5?!
It's surprising to see a good player make such a weak move. Why did he play it? Probably because I had played the Exchange Variation in 2 previous matches vs. Hamilton. [However, as explained in Moldovan - Demetrick : KST 2007, >=4...Qxd5 ; or 4...Bb4+ ]

5.e4 Nf6 6.Nc3 c6 7.Bd3
[Moldovan - Quinones : USATE, Parsippany 2008 went 7.h3 Bb4 8.Bd3 0-0 9.0-0 Nbd7 10.e5 Nd5? 11.Bxh7+!+- & 1-0 (20). ]

7...Be7 8.0-0 0-0 9.Qc2
Threatening to win a P with 10.e5.Diagram

[Predecessor (4): 9...h6 10.Bf4 Nbd7 11.Rfd1 b6 12.Rac1 Bb7 13.Qe2 Re8 14.e5 Nd5 15.Nxd5 cxd5 16.Ne1 Rc8 17.Rxc8 Bxc8 18.Rc1 Bb7 19.Qg4 Kh8 20.Nf3 a6+/= Rodrigues - Louro : LSS email 2008 (1/2-1/2, 67)]

10.Be3 Nd7 11.Rad1 Qa5 12.a3 g6 13.Qd2
Threatening a double attack upon the unprotected Qa5 and Be7.


This nets the B pair, leaves Black weak on the dark squares and completely refutes his opening.

[Not 14...Bd8? 15.b4!+- /\Qxa3 16.Ra1 winning the Q for a R, N & P.]

15.Nxe7+ Qxe7 16.Bh6
[>=16.Qc3 Re8 17.Rfe1+- /\e5? 18.dxe5 Nxe5? 19.Nxe5 Qxe5 20.Bd4 skewering the Ng7.]

16...e5 17.Qc3 Re8 18.Rfe1
[I looked at 18.Bc4 /\exd4 19.Qxd4 Ne5 but missed 20.Ng5!+- Nxc4?? 21.Qxg7# ]


This leads to a trade-down and lessened advantage. [>=19.Nxd4 /\Qh4?? 20.Bxg7 Kxg7 21.Nf5+ Kg8 22.Qg7# ]

19...Ne5 20.Nxe5 Qxe5 21.Qxe5 Rxe5 22.Bc4
[>=22.f3+/- ]

Of course, if the R attacks either B, Black gets mated.

>= Bf1 here or next.

23...Be6 24.Bxe6 Nxe6 25.Rd7 b6 26.Be3
[>=26.Red1 with an edge.]

Now White has nothing. Diagram

27.Red1 Red8 28.Rxd8+ Rxd8 29.Rxd8+
I offered a draw here but Charles wanted to play on.

29...Nxd8 30.Kf2 f6 31.Ke2 Kf7 32.Kd3 Ke6 33.b4 cxb4 34.axb4 Kd6 35.Bd4 f5 36.exf5 gxf5 37.g4 fxg4 38.fxg4 Kd5 39.h4 Nc6

Drawn by agreement, after Black's proposal. Time left - Moldovan 17:19, Miller 58:35 Estimated time used - Moldovan 60:56, Miller 19:40 Longest think by White - 12 minutes for 18.Rfe1 Longest think by Black - 2 minutes for 16...e5 and 22...Re8. I am disgusted with my failure to convert the big advantage. A win would have split the match. [Black wins a P after 39...Nc6 40.Bc3 Ne5+ 41.Bxe5 Kxe5 42.b5 Kf4 43.g5 Kg4 44.Ke4 Kxh4 but 45.Kf4 keeps him from making headway.] 1/2-1/2
