Jerome Gambit: I Am Glad That I Read This Blog

I know that I have said before that I am glad that I read this blog, but my most recent Jerome Gambit game reinforced this habit - on the day the previous post appeared, I played the following game. Using "The Machine Idea", I quickly developed an advantage. Despite my opponent's efforts at counter-attack, and the time ticking off my clock, I was able to construct a checkmate.

perrypawnpusher - Praotorian

5 5 blitz, FICS, 2017

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 



7.Qf5+ Kd6 8.f4 Bd4 

An idea favored by some chess computer programs, looked at in Petasluk - GriffyJr, blitz, FICS, 2017, (0-1, 30).

9.fxe5+ Bxe5 

Instead of this capture, Stockfish 8 recommends the following line, which takes the game in a very different direction, but which winds up with a small advantage for Black: 9... Kc6 10.c3 d6 11.e6 Ne7 12.Qf1 Rf8 13.Qc4+ Bc5 14.a4 a6 15.d4 b5 16.Qe2 Ba7 17.axb5+ axb5 18.d5+ Kb7 19.Qxb5+ Bb6 20.Ra3 Rxa3 21.Nxa3 Ka7 22.Qa4+ Ba6 23.Nc2 Qe8 24.Qxe8 Rxe8. White has three pawns for the sacrificed piece, but Black has the two Bishops.

10.d4 

I remembered GriffyJr's improvement.

10...Bxd4 

A blitz move. Black's best was the counter-attack with 10...Qh4+.

11.Qd5+ Ke7 12.Qxd4 Qe8 13.Bg5+ Kf8 


Material is even, but White's attack is deadly. Stockfish 8 comlained after the game that 13...Kf7 would have held out longer, but I still would have had a significant advantage.

14.O-O+ Nf6 15.Bxf6 gxf6 16.Rxf6+ 


Good enough to win, but a post mortem suggested 16.Qxf6+ Kg8 17.Qg5+ Qg6 18.Qe7 Qe8 19.Qxe8+ Kg7 20.Qe5+ Kh6 21.Rf6+ Kg7 22.Qg5 checkmate. This is a good maneuver to remember - even in time pressure. 

16...Kg8 17.Qd5+ Kg7 18.Qg5+ Qg6 19.Rxg6+ hxg6


 White has a Queen and a couple of pawns for a Rook - if he can manage his clock. Unfortunately, although my opponent's time was moving quickly, mine was falling even faster. My opponent was aware of this, and continued to fight.

20.Qe5+ Kg8 21.Nc3 d6 22.Qf6 Rh7 23.Rf1 Bd7 


Heh. In the Jerome Gambit I sacrifice two pieces and challenge my opponent: show me your win. Here Praotorian throws the challenge back at me.

24.Qxg6+ Rg7 25.Qf6 Kh7 26.Rf4 d5 27.Rh4+ Kg8 28.Nxd5 Rf8 

Everything is fine, but tick, tick, tick...

29.Qc3 Bb5 30.Ne3 Be2 31.Nf5 Rgf7 32.Qh8 checkmate

It is a good thing that you are glad that you read this blog because, as long as you continue blogging on here, I think it would be difficult for you to avoid reading it... although blindfold blogging could be good training...

Kevin,
I will have to try blindfold blogging sometime! Can you recommend a time control for it?
In the meantime, I will continue to try to remember what I have researched and posted, just in case it becomes handy again...

Hmm, I like to play blindfold chess games on FICS and Chess.com with 10 or 12 minutes each on the clock so maybe that is a suitable time control. Lol, I bet you could blog the first 4 moves of a Jerome Gambit quite easily blindfold ;)
