1.e4 c5 2.c3 d5 3.exd5 Qxd5 4.d4 Nc6 5.Nf3 Nf6 The point of Black's move order is that if White plays 6 Bd3 then the move 6 ... Bg4 is still available, as Black has not yet played ... e7-e6; if White plays 6 Be2 then Black can play the isolated queen pawn position after 6 ... cxd4 7 cxd4 e6 where White's king bishop is passively misplaced. 6.Be3 Also popular here is 6 Na3. 6...Ng4 7.Bg5 In Colding - Rohde, NY 1996, 7 Nbd2 was played, but I was comfortable after chopping off the bishop.

WIth the text Chow tries to prove that the knight on g4 is misplaced. 7...e5 8.Nbd2 cxd4 9.Bc4 Qa5

10.cxd4 The critical alternative here is 10 Qb3, but Chow did not like 10 ... f6 keeping the extra pawn for good. It seems to me, however, that White's compensation is reasonable. 10...h6 11.Bh4 g5 12.Bg3 e4 13.Ne5 Much better was 13 Qe2 f5 14 O-O, even though Fedorowicz advanced his kingside pawns to inhibit this line. After 14 ... Be7 15 d5, I prefer White. 13...Ncxe5 14.Bxe5 Nxe5 15.dxe5 Bf5 Suddenly Black is threatening 16 ... Rd8, and White is in big trouble. 16.Qe2 Bb4 17.Rd1 0-0-0 18.a3 Bxd2+ 19.Rxd2 Bg6 20.b4 Qxe5 21.0-0 Rxd2 22.Qxd2 Rd8 23.Qe3 Kb8 24.Rc1 f5 Black is a pawn up with a dominating position.
