Nightmare


I have seen computers grind people down, and punish them for tactical oversights. I was a bit disturbed by the King hunt in the following game, too.

It's important to remember: it's not Bill so much as it's the Jerome Gambit, responsible for the loss.

Wall, Bill - Andscacs engine
Palm Bay, FL, 2015

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 




4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.f4 d6 

The computers' favorite, the "annoying" or "silicon" defense.



8.fxe5 dxe5 9.Qh3+ Kf7 10.Rf1+ 

This is a change from 10.Qh5+ as seen in Wall,B - Bison engine, Palm Bay, FL 2015 (1/2-1/2, 67) but it may not be an improvement. The Andscacs engine declines to transpose into that game, and for White there may be an advantage in using the earlier Queen check (at h5), provoking ...g6, before Black's King can retreat to g8, as it does in this game.

10...Nf6 11.Qh5+ Kg8 12.Qxe5 Bd6 13.Qg5 h6 14.Qh4 Qe7



White's King, not Black's, is at risk. Ominous.

15.d4 Nxe4 16.Qxe7 Bxe7 17.Bf4 Bh4+ 18.Ke2 Bg4+ 19.Kd3 Bf5 20.Kc4 b5+ 21.Kxb5 Rb8+ 22.Ka5 Rxb2 23.Bxc7 g6



24.g3 Be7 25.c3 Rh7 26.g4 Bd7 27.Rc1 Bd6 28.Bd8 Nc5 29.dxc5 Bxc5 30.Ka6 Bb6 31.Bxb6 Bc8+ 32.Ka5 axb6+ 33.Ka4 Ra7 checkmate
