Bots on Our Side (Part 2)





As I noted in the previous post, I have written here about computer vs computer Jerome Gambit games, and about human vs computer Jerome Gambit games (see "Ionman vs the Bots").

The other day I also ran into some games in The Database where a computer, GriffyJr at FICS - which had starred as the defender against Ionman in the Jerome Gambit games mentiond above - was playing White.

Like the play of GriffySr, I wanted to see what "junior" was playing!



GriffyJr - ManOOwar
FICS, 2003

1.e4 e5 2.Nf3 Nc6 3.Bc4 h6 




The Semi-Italian game. If Black plays ...Bc5 at some point, it can turn into a Jerome Gambit. White needs a "waiting" move or two.

4.d4

Or 4.c3 Nf6 5.d4 d6 6.dxe5 Nxe5 7.Nxe5 dxe5 8.Bxf7+ Ke7 9.Qxd8+ Kxd8 10.Nd2 Bd6 11.b4 Rf8 12.Bc4 Bd7 13.O-O b5 14.Bb3 Re8 15.a4 bxa4 16.Bxa4 Bxa4 17.Rxa4 Ke7 18.Rd1 Reb8 19.f3 Kf8 20.Nc4 Rd8 21.Be3 a6 22.Rda1 Ne8 23.b5 a5 24.Nxa5 Be7 25.Nc6 Rxa4 26.Rxa4 Rd3 27.Kf2 Rxc3 28.Nxe5 Bd6 29.Ng6+ Kf7 30.Nh8+ Kg8 31.Ng6 Rc2+ 32.Kf1 Rb2 33.e5 Bf8 34.Rf4 Rb1+ 35.Kf2 Rb2+ 36.Kg3 Black forfeited on time, GriffyJr - ABOSS, FICS, 2009.

5.Bxf7+ 

GriffyJr treats the position as if it were a Blackburne Shilling Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4 4.Bxf7+). White's loss of his d-pawn actually helps the attack. 

5...Kxf7 6.Nxe5+ Ke8

This move allows a forced checkmate - which GriffyJr misses!

No matter; White still has a won game.

Not much better was 6...Ke6 7.Qxd4 Nf6 8.Ng6 Kf7 9.Nxh8+ Kg8 10.Ng6 c5 11.Qd3 Be7 12.O-O d6 13.Bf4 Qb6 14.Nxe7+ Kf7 15.Bxd6 Qxb2 16.Nc3 Be6 17.e5 Nd7 18.Qg6+ Kf8 19.Nf5+ Kg8 20.Qxg7 checkmate, GriffyJr - itsanelmo, FICS, 2009.

8.Ng6+

The mate is 8.Qf7+ Kd6 9.Nc4+ Kc5 10.Qd5+ Kb4 11.Bd2+ Ka4 13.Qa5, the same idea as in the later game against augustwest, above.

8...Kf6 9.Qh4+

Instead, 9.Nxh8 was stronger, but the bot knows that many human players do not like to lose their Queen...

9...Kxg6 10.Qxd8 Be7 11.Qxc7 Black resigned


These moves also occurred in GriffyJr - materialist, FICS, 2001
