Speechless



I really didn't know what to say about the following Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) game, so I turned it over to my computer. The analysis is by Rybka 3, inside the Fritz program; so the comments come from Fritz 8. I made the diagrams, though.

Warning: the machine is rather cold-hearted in its evaluations.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+


4...Kxf7 5.0-0 Nf6

6.c3 Rf8 7.d4 exd4 8.Qb3+?


Better was: 8.e5!? Nd5 9.b4 -/+

8...Ke8

8...d5 might be the shorter path: 9.Bg5 Bb6 10.Nbd2 -+

9.Re1

9.e5 Ng4 10.Bg5 Be7 11.Bxe7 Qxe7 -+ ( 11...Nxe7?! 12.Re1 -/+; 11...Kxe7?! 12.cxd4 Rf5 13.Qd5 =/+)

9...d6

9...Qe7 10.h3 -+

10.cxd4

Better was: 10.Bg5 -+

10...Bb6??

Forfeits the advantage. Better was 10...Bxd4, the advantage is on the side of Black, 11.Bg5 h6 12.Nxd4 Nxd4 ( 12...hxg5?! 13.Nxc6 bxc6 14.e5 -+) 13.Qa4+ Nc6 -+

11.e5 -/+ dxe5 12.dxe5??
Better was: 12.Nxe5 the rescuing straw 12...Ne7 13.Nc3 =/+

12...Ng4 -+ 13.Bg5

13.Be3 Nxe3 14.fxe3 Bg4 -+

14.e6

14.Bh4 g5! the final blow 15.e6 -+

14...Qd6 15.e7 Rf7

Better was: 15...Bxf2+ and Black takes home the point 16.Kf1 Bxe1 17.exf8N Kxf8-+ ( 17...Qxf8?! 18.Kxe1 h6 19.Bh4 -/+)

16.Qxf7+! Kxf7 17.e8Q#

16...Bxf2+
16...Bd7!? 17.Ne4 Bxf2+ 18.Kf1 -+

17.Kh1 Rxf3??
Makes life more difficult. Better was 17...Bxe1 Black had this great chance 18.Nb5 Bg3 19.Nxd6+ Bxd6 -+

18.Qg8+ Rf8 19.exf8Q+

19.Qxf8+ Kd7 20.e8Q#

  1. I'd just like to point out that I did have mate on the move myself :)

  2. Pete,

    When I first played through the game, I thought the Rook sac delivered the mate for Black -- instead, the game stood on its head. That's when I turned it over to the silicon geniuses to figure out...
