Jerome Gambit: Too Fast, Too Furious (Part 1)

I was playing my last game in the first round of the "Let's Play The Italian Game" tournament at Chess.com when, suddenly, two opponents made their moves against me in new games. Apparently, the computer scheduler had decided that I would progress to the second round of play, even if I lost the first round game (I didn't; I won it) - so, there I was, with two second round games.

Somewhat disconcerting, each of my opponents was playing quickly - in fact, one of my games ended after a day of play, rather fast given that the time control was one move per day.

Still, I was willing to move with speed, too, as we were contesting a Jerome Gambit - in a line that I had visited several times before. (Alas, I lost the other 3 games, so no more "next" round for more Jeromes.)

 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 

7.Qd5+ 

Years ago, I labeled this finesse "a nudge". It is as old as Jerome - Brownson, Iowa, US, 1875 (1-0, 28). In a blitz game, it can get Black wondering what White is up to - using up precious time.

7...Ke8 8.Qxc5 d6 9.Qe3 

After the game, I put Stockfish 9 in "blunder check" mode to look at the game. Initially, it liked 9.Qc3 Qg5 10.Qg3 Qxg3 11.hxg3, with Black's advantage less than a pawn. That seems a bit silly to me, White moving his Queen 5 times, only to let it be exchanged.

According to The Database, I have reached the diagrammed position 83 times in my games. I must have learned something about the line.

9...Nf6 10.O-O Kf7 

Black sensibly prepares to mobilize his Rook, and possibly castle-by-hand.

A major alternative is 10...Ng4.The proper response is 11.Qg3!,and this is reminiscent of the series of posts I did a while back on "Jerome Gambit Secrets". A strong and experienced Jerome Gambiteer tried 11.Qe2, instead, and perished quickly: mrjoker - weiran, ICC, 2008 (0-1, 14). Another played 11.Qc3 and needed all of his Houdini-like powers to escape and turn the tables: Wall,B - Guest1660564, PlayChess.com, 2013 (1-0, 32). 

I have played 11.Qg3 with mixed results: perrypawnpusher - lorecai, blitz, FICS, 2011 (1-0, 14), perrypawnpusher - jgknight, blitz, FICS, 2011 (1/2-1/2, 49), perrypawnpusher - FiNLiP, blitz, FICS, 2011 (0-1, 59). For a couple of more modern examples, from stronger players, see Sheldrick,K - Bhat,V, Australian Open, 2017 (1-0, 20) and Morin,L - Weston,P, Quebec Open, 2018 (1-0, 54)

11.f4 Re8 12.f5 

I have been pretty successful with this thematic move (10 - 4 - 1), chasing the Knight, so I was surprised to see, after the game, that Stockfish 9 recommended 12.Qb3+!? instead. The Database has only one game with that move, a win by Black in 25 moves.

12...Ne5 13.d4 

Here, again, the computer prefers 13.Qb3+, followed by 14.d3, which seems to lock the Queen on the Queenside. (There are no game examples in The Database.) As we will see, Stockfish's preference is based on disliking Black's next move.

13...Neg4
