Jerome Gambit: Antonio-bot (Part 1)



After matching wits with Chess.com bots Deadlost and Grandpa Gambit, I decided to challenge the "advanced" bot, Antonio.

Antonio prides himself on being a balanced player. He doesn't win every game, but don't expect to beat him without a fight.

Antonio did very well against the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) - up until an ill-advised return of sacrificed material. After that, trouble snowballed.

Comments by Antonio are in brown.

1.e4

Sicilian today, or something else?

1...e5

Let's play an open game.

2.Nf3

What are you up to?

2...Nc6

"I don't believe in psychology. I believe in good moves." - Bobby Fischer

3.Bc4 Bc5 4.Bxf7+

I believe in psychology and good moves - Rick

Take that one off the board.

4...Kxf7 5.Nxe5+

Is that my king you're pointing at?

5... Nxe5 6.Qh5+ Ke6

7.Qf5+ Kd6 8.f4 Ng6 

According to The Database, this is the reply to 8.f4 is seen about 1/6 of the time. Black saves the Knight. 

9.Qd5+ Ke7 10.Qxc5+ d6 

Do you see my plan?

11.Qe3 


This is the 10th time that I have arrived at this position.

I suspect that after each of those games, the computer suggested that 11.Qc3 was better. I have yet to take that advice.

11...Kf7 

Antonio moves his King out of the eventual line of fire, the e-file.

12.O-O Nf6 13.f5 Ne7 14.d4 


Here we have the classic Jerome Gambit battle of White's 2 extra "Jerome pawns" against Black's extra piece.

Stockfish 15.1 (34ply) rightly assesses the defender as being about a little bit less than a pawn better.

14...Ng4 

Suddenly the bot shows human tendencies: Let's attack the Queen!

Consistent would have been 14...Re8 with still the better game.

15.Qg5 

Stockfish 16 prefers 15.Qb3+ here, but I am never sure if this is a strong move, or just a distracted, harrasing one. 

15...Nf6 

No harm, no foul? The computer thinks so.

16.e5 


There is a tactical "hole" in this idea that neither I nor my opponent noticed. Black now has 
16...dxe5 17.dxe5 Qd4+!? 18.Qe3 Qxe3+ 19.Bxe3 Nxf5 20.Bd2 Ng4 21.h3 Nxe5 22.g4 Kg6 23.gxf5+ Bxf5 and would remain ahead. 

16...Ne4 

Let's attack the Queen!

17.e6+ 

This move is okay, and has attacking ideas behind it, but more accurate would have been 17.Qh5+ Kg8 18.f6 breaking lines open.

17...Kg8 18.Qh4 Nf6 19.Bg5 

This is a comfortable position for White, if only because it is an uncomfortable position for Black.
