1.e4 d5 2.exd5 Nf6 3.d4 Bg4 4.f3 Bf5 5.c4 e6 6.dxe6 Nc6! 7.Be3
[7.exf7+? Kxf7 8.Be3 Bb4+ 9.Nc3 Re8 10.Kf2 Rxe3! 11.Kxe3 Bc2! 12.Qd2 (12.Qxc2 Qxd4+ 13.Ke2 Re8+-+ ) 12...Ng4+!!-+ is an example of some nasty home analysis I cooked up for anyone greedy enough to want to take on f7.]

7...fxe6 8.Nc3 Nb4!
An improvement on Tindall-West which Black won rather unconvincingly.

9.Rc1 c5 10.d5?!N
[White's best is 10.Qa4+! with the prospect of an edge, in complex play. As far as I know it's only been played once.]

10...exd5 11.cxd5 a6
Black can take the pawn on d5 straight away but the text keeps greater complexity and maintains pressure on White to solve his development problems. [11...Nfxd5 12.Nxd5 Qxd5 (12...Nxd5 13.Bb5+ Kf7 14.Bc4 Be6=/+ ) 13.Qxd5 Nxd5 14.Bf2=/+ (14.Bxc5? Rc8-+ ) ]

Trying to punish Black for not regaining the pawn, but White's development lag is becoming serious. [>=12.Kf2=/+ ]

12...Be7 13.d6?!
[13.a3 Nfxd5 14.Nxd5 keeps Black's advantage to a minimum.]

13...Bxd6-/+ 14.a3 Qe7+! 15.Kf2 Be5!
The point of Black's last move. This piece sacrifice to exploit the weakened dark squares is the blow that brings White's problems out into the open.

[Accepting the piece leads to quick disaster. 16.axb4? Bd4+ 17.Kg3 Qe5+ 18.f4 (18.Kh4 h6-+ ) 18...Qe3+ 19.Qf3 Qxc1 20.h3 Qxb2-+ ]

16...Rd8 17.Bd2?
White's last chance to try and defend was 17. Qa4+, but it looks grim.

17...Bd4+ 18.Kf1 Nd3
More artistic than 18...Be3 when White can struggle on by sacking his Queen.

19.Bxd3 Bxd3+ 20.Nge2 0-0 21.Bg5 c4 22.Qd2 h6 23.Bxf6 Rxf6
A picturesque position, with White almost completely paralysed by the bishop pair and Black threatening to triple on the e-file and then take the knight on c3.

24.Re1 Rxf3+!
Forcing mate in 4.

25.gxf3 Qh4
Now if 26. Ne4 Qh3 is mate and 26. Kg2 Qf2+ 27. Kh3 Bf5 is also mate. 0-1
