Jerome Gambit: Boris Trapsky (Part 2)

 

Wanting to learn more about the computer chess program Boris Trapsky (see "Jerome Gambit: Boris Trapsky [Part 1]") I downloaded a collection of its games.

Just my luck, I found several games with openings similar to the Jerome Gambit.

And then I found a Jerome. 

Boris Trapsky - Clasassin

10 5 rapid, lichess.org, 2024

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.O-O 

Interesting. Sacrificing one piece is enough for Boris Trapsky. Perhaps it draws inferences from how Black responds.

5...Nf6 6.d4 Nxd4 7.Nxe5+ Kg8 8.c3 Nc6

White is down a piece for a pawn, and has another piece hanging.

What to do?

9.g4

Wow. The computer does like to gamble. Surely, Black can just take the pawn?

9...Nxe5 10.g5

Wow, again. I know that Boris Trapsky is rated about 550 points above its opponent, but does it know that?

10...d5 

Returning a piece.

11.gxf6 Qxf6 

Black offers another piece.

12.Qxd5+ Be6 13.Qxc5 

Stockfish 16.1 sees Black's position as more than a Rook better than White's.

13...Nf3+ 

Better is 13...Bh3, but Black thinks about a different way to attack the King.

14.Kh1 Qh4 

15.Qxc7 h6 

Luft. It was also possible to grab a pawn and pursue tactics, with 15...Qxe4.

16.Nd2 Nxd2

Suddenly, the game is even. Hindsight suggests 16...Rf8.

17.Bxd2 Qxe4+ 18.f3 Qe2 

The human has defended well, but now the game begins to slip away.

19.Rae1 Qxd2 20.Rxe6 Kh7 

Giving his King more shelter - and walking into a forced checkmate.

21.Re7 

Missing 21.Rg1 Qg5 22.Rxg5 hxg5 23.Re7 Rae8 24.Rxg7+ Kh6 25.Qf7 Re1+ 26.Kg2 Re6 27.Kg3 Rc6 28.f4 gxf4+ 29.Kh4 f3 30.Rg4 Rg8 31.Qh5# - but wouldn't we all?

The text is still winnng.

21...Rhg8 22.Rg1 Kh8 23.Rexg7 Qxb2 24.Rh7 checkmate
