1.d4 d5 2.c4 c6 3.Nf3 Nf6 4.e3 g6 5.Nc3 Bg7 6.Be2 0-0 7.0-0 Bg4
Often, in Queen Pawn openings, Black has to suffer with a bad Bc8. Here, Black tries to develop it.

8.cxd5 cxd5 9.Qb3
Taking immediate advantage of the fact that the b7 pawn is now undefended.

9...b6 10.Bd2 Nc6 11.Rfc1 Na5 12.Qd1 Bxf3 13.Bxf3 e6
Black has solidified the center, traded off the bad light-squared bishop. Looks fine, right?

14.b3
Preventing Na5-c4

14...Qd6 15.Be2
Re-posting the bishop to the more active diagonal

15...a6
Diagram The losing move

16.Qf1

Leaving the Na5 exposed.

17.Nxd5 Nxd5 18.Bxa5
With an extra pawn, the two bishops, and an open board, an easy win for Ms. Humpy.

27.Rab1 Re8 28.Bd3 Kg7 29.Kf2 Rec8 30.Ke2 Be5 31.Rxc5 Rxc5 32.h3 a5 33.b4 Rc3 34.bxa5 Ra3 35.Rxb5 Rxa2+
But with a pair of rooks on the board, white will have excellent winning chances.
