Disaster Strikes the Computer

As a followup to the human vs computer game Wall - Akok, 2015 the following game addresses a 12th move alternative for Black. At that point things have gotten critical for the defender (see the notes in "Irrational"), but it would be a shame to hide the current contest in the notes of another game: once again, disaster strikes the computer.

Wall, Bill - Amyan 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 Qf6 

8.Rf1 g6 9.Qh3+ Ke7 10.Nc3 Kd8 11.fxe5 Qxe5 

The Black King is not as safe as it would like, and the Black Queen's capture is ill-fated. White's next move shows that the defenders are over-worked.

12.d4 Qxd4

Wall - Akok, 2015 saw 12...Bxd4

13.Bg5+ Ke8

Costing material, despite the eventual Queen exchange, is 13...Ne7, i.e. 14.Bf6 d6 15.Qg3 Qe3+ 16.Qxe3 Bxe3 17.Bxh8.

14.Qf3 Qg7 15.Nd5 Bd6 16.O-O-O 

Who wouldn't want to have this position with White against a computer?


You know that Black is in trouble when the best line Stockfish recommends is 16...Be5 17.Qc3!? Things would continue dismally: 17...Bf4+ (everything else leads to checkmate) 18.Rxf4 Qxc3 19.bxc3 Ne7 20.Nxc7+ Kd8 21.Nd5 Ke8 22.Bxe7 Rb8 23.Rdf1. 

17.e5 Bb8  18.e6 d6

 Black, trying to keep the position closed, doesn't have time right now to take the offered Knight. Alas, undeveloped, there is also the problam of a pesky "Jerome pawn".

19.Qf7+ Qxf7 20.exf7+ Kf8 21.fxg8=Q+ Kxg8

22.Rde1 cxd5 23.Re8+ Kg7 24.Re7+ Kg8 25.Bh6 Black resigned

Next is checkmate.
