Jerome Gambit: Escaping the Mania (Part 1)



I recently took on another bot at Chess.com, and, in time, things became balanced - a bit unusual for an opening that has two pieces sacrificed.

If Readers find the line of play to be interesting, there are many links to other, related Jerome Gambits to check out.


perrypawnpusher - LarryFitzgeraldBot

Chess.com, 2023

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Nc3 Bc5 5.Bxf7+ 

The Italian Four Knights Jerome Gambit.

The Database has 3,343 examples, with White scoring 40%; compared to 33,916 games with the basic Jerome Gambit, 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+, with White scoring 52%

Happily, in my 69 games with the Italian Four Knights Jerome Gambit, I have scored a more substantial 77%.

5...Kxf7 6.Nxe5+ Nxe5 

Once, I met 6...Ke8 in perrypawnpusher - opazovalec, 10 2 blitz, FICS, 2014 (1-0, 16). 

7.d4 Bd6


LarryFitzgerald's move is natural enough, although I have met others:

7...Neg4 in perrypawnpusher - xxfred, 2 12 blitz, FICS, 2012 (0-1, 28); 

7...Bxd4 in perrypawnpusher - Fazmeister, 2 12, blitz, FICS, 2011 (1-0, 36) and perrypawnpusher - spince, 2 12 blitz, FICS, 2014 (0-1, 41); 

7...Bb4 in perrypawnpusher - kezientz, 10 0 blitz, FICS, 2010 (1-0, 9); perrypawnpusher - Abatwa, 12 4 blitz, FICS, 2010 (1-0, 17); perrypawnpusher - Gibarian, 6 6 blitz, FICS, 2010 (1-0, 33); perrypawnpusher - obmanovichhh, 14 0 blitz, FICS, 2010 (1-0, 39); perrypawnpusher - LydenChess, 2 12 blitz, FICS, 2011 (1-0, 15); perrypawnpusher - Aerandir, 4 12 blitz, FICS, 2011 (1-0, 15); perrypawnpusher - SSGSSGSSG, 5 5 blitz, FICS, 2018 (1-0, 20); 

7...Re8 in perrypawnpusher - strandskatan, 5 5 blitz, FICS, 2013 (1-0, 38); perrypawnpusher - hklett, 2 12 blitz, FICS, 2013 (1-0, 31); 

7...Nd3+ in perrypawnpusher - genericme, 10 0 blitz, FICS, 2015 (1-0, 22); and

7...Nf3+ perrypawnpusher - wertu, 2 12 blitz, FICS, 2010 (1-0, 20) and perrypawnpusher - catmandu, 2 12 blitz, FICS, 2014 (0-1, 12).

8.dxe5 Bxe5 9.f4 

Probably better is 9.Ne2 as in perrypawnpusher - lixuanxuan, 14 0 blitz, FICS, 2014 (1-0, 22);  perrypawnpusher - andrewLLL, lichess.org, 2020 (0-1, 18); perrypawnpusher - LttlePrince, lichess.org, 2020 (0-1, 29); and perrypawnpusher - rusalka, 2 12 blitz, FICS, 2023 (1-0, 17) 

9...Bxc3+  10.bxc3 

10...b6

Or 10...d6 as in perrypawnpusher - joseluislopez, blitz, FICS, 2012 (0-1, 55). 

11.e5 Ne4 

I wondered if the bot was going to grab the e-pawn on move 10. Instead, he puts his Knight on e4 on move 11 - with equally unfortunate results. Continuing as planned with 11...Bb7 was best; and 11...Qe7 was good, as well.

12.Qd5+ Kf8 

Here, we have a basic choice: which piece to capture?

It is interesting that, after the game, Stockfish 15.1 recommended checking the King and then grabbing the Knight, i.e. 13.Ba3+ Ke8 14.Qxe4, slightly ahead of grabbing the Rook directly with 13.Qxa8. Simply grabbing the Knight with 13.Qxe4 was ranked even below 13.0-0.

So, you can guess my move...

13.Qxe4 

White is still better, with more material, better center control, and a safer King.

13...d5 14.exd6 

Probably 14.Qf3 was better, preserving the advanced, supported d-pawn. 

14...Bd7 15.dxc7 Qe8 16.Ba3+ Kf7 17.Qxe8+ Rhxe8+ 


My tripled, isolated c-pawns look vulnerable on the c-file. Will the Bishops-of-opposite-colors turn the game drawish?

18.Kd2 Rac8 19.Rae1 

It would have made more sense (and been stronger) to play 19.Bd6.

19...Be6 

In turn, 19...Rxc7 was the move. 

20. Kc1 h6 21.Kb2 Rxc7 

Things have turned drawish. I suppose that means that both of us have escaped the mania of the Jerome Gambit.

But there is still more chess to play.
