Jerome Gambit: Stockfish vs Stockfish



The final game from Boris shows that Stockfish 11 cannot give itself "Jerome Gambit odds". Go figure.

I don't have suggestions on how to improve White's chances, except "Don't play the Jerome Gambit against computers".


Stockfish 11 - Stockfish 11

computer vs computer, 2020


1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 

7.f4 d6 

The "silicon" or "annoying" defense, so called because it is the choice of different computer programs, and can be quite annoying to face. White can have a hard time getting something started against the centralized King.

8.fxe5 dxe5 9.Qh3+ Ke7 10.Qg3 Kf7 

11.Rf1+ Nf6 12.Qxe5 

White has 2 pawns for the sacrificed piece, and in a club level human vs human game, might have some chances. 

12...Bd4 13.Qh5+ Kg8 14.Qe2 Be6 


15.h3 c5 16.c3 Be5 17.d3 Qd6 18.Be3 Rd8 19.Nd2 Bg3+ 20.Kd1 Qxd3 21.Qxd3 Rxd3 


22.Rf3 Be5 23.Kc2 Rd8 24.a4 h6 25.a5 Kh7 26.g4 Nd7 27.Rg1 g5 28.Rf2 Kg6 29.Rfg2 Rhf8 


Black's Rooks occupy the 2 open files. White's Rooks over-protect a pawn.

30.b3 Bd6 31.Rf1 Rxf1 32.Nxf1 Rf8 33.Nd2 Bc7 34.Rg1 Bxa5 35.Ra1 Bb6 36.b4 cxb4 37.Bxb6 axb6 38.cxb4 


White's passed pawn is not sufficient compensation.

Black makes use of his extra piece.

38...Rc8+ 39.Kd3 Ne5+ 40.Kd4 Nc6+ 41.Kc3 b5 42.e5 Bd5 43.e6 Bxe6 44.Re1 Bd5 45.Nb3 Nd8+ 46.Nc5 Ne6 47.Rd1 Nf4 48.Kb2 Re8 49.Nd7 Re3 50.Nc5 Rxh3 White resigned

I suppose I'm going to have to ask Stockfish 11 to spend a bit more time trying to solve the "silicon" defense.

By the way, The Database has 214 games with the "silicon" defense, and White scores 55%. Again, go figure.
