Like the Big Boys

I like playing over the Jerome Gambit games of Bill Wall, mrjoker and axykk. They look like patient predators, sitting, waiting, waiting, waiting... and then pouncing on their prey.

The following game of mine is a little like that. Except for the "pouncing" part.

 
perrypawnpusher - pitrisko
blitz, FICS, 2011

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


4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6


7.Qd5+ Ke8 8.Qxc5 d6 9.Qe3 Nf6


I have had this position in over 30 games, scoring over 80%. I don't have it quite mastered, but I can get to it quickly (and that counts in blitz).

10.0-0 Ng4 11.Qg3

Surprisingly bad is 11.Qe2 which unravels quickly: 11...Qh4 12.h3 Nf4 13.Qf3 Ne5 14.Qc3 Ne2+ 'Nuff said.

11...Qh4

Forcing the exchange of Queens. For 11...h6 see perrypawnpusher - lorecai, blitz, FICS, 2011, (1-0, 14) and for 11...h5 see perrypawnpusher - Riversider, blitz, FICS, 2010 (1-0, 18)

12.Qxh4 Nxh4

I don't play the Jerome Gambit with a Queenless middlegame in mind, but it can't be helped. I decided a while back that in this position it didn't pay to spend any time (on the clock) worrying, I needed to make the swap and then move on.

13.f4 Nf6 14.Nc3 Ng6 15.f5 Ne5

This gives away more tempos to the "Jerome pawns", and White is now close to having full compensation for his sacrificed piece. 

16.d4 Nc6 17.e5

It was easier to decide on this move here than it was in my game against mtibuk.

17...dxe5 18.dxe5


18...Ng4

Black does not want to give the piece back with 18...Nxe5 19.Re1, etc., when White would have an edge; but perhaps he should have. 

19.e6

This move is okay, but after the game Rybka 3 preferred 19.Nb5 Kf8 20.e6 b6 21.Nxc7 Rb8 22.Bf4 with the idea 22...Bb7 23.Bd6+ Ne7 when White will be able to win the exchange with 24.Nd6, adding to his three-pawns-for-a-piece material balance and Black's blocked King Rook.

This is certainly a position I need to return to and study some more.

19...Rf8

Instead, Black had a chance to prepare a better defense by playing 19...Ne7, so that if 20.Nb5, then 20...Nd5.

20.h3

Missing 20.Nb(or d)5 entirely. It could also be played on my next move, with advantage.

20...Nf6

21.Bf4

I was happy with my game so far. I had kept everything in balance,
keeping a roughly even game, just like the "big boys", and all I needed was a slip by my opponent to take advantage of. 

21...Nb4 22.Bxc7 Nxc2 23.Rac1

Sensible.

Rybka 3's suggestion shows chess being played at a higher level than either my opponent or I were capable of in this game: 23.Rad1 (attacking the back rank) Bxe6 (forced, but useful) 24.fxe6 Ne3 (has White blundered??) 25.e7 Rg8 26.Rd8+ Kxe7 27.Rxa8 Rxa8 (White's "Jerome pawns" have disappeared, but that is all that he has to regret) 28.Re1 Kd7 29.Rxe3 Kxc7 30.Re7+ Kc6 31.Rxg7. White has won a pawn, but the endgame looks tricky.

Strong chess players can get blood from a stone.

23...Ne3 24.Rf3 Ned5 25.Nxd5 Nxd5 26.Bd6 Ne7


Finally Black slips, and it is time to pounce!

27.Rfc3

No, this not it. It is a paw swipe, not a pounce.

With the pressure from 27.Rc7  Black is forced to liquidate with 27...Nxf5 28.Bxf8 Bxe6 29.Bxg7 Rd8 30.g4 Nxg7 31.Rxg7 Rd7 32.Rxd7 Kxd7 and White is up the exchange and a pawn.

That is not a lot, but it is enough to win the endgame.
Black now wisely gives back his extra piece for the two "Jerome pawns" and the game slides into a draw...

I pursued things for a while, waiting for another chance to "pounce" but it was not to be.

27...Rxf5 28.Bxe7 Kxe7 29.Rxc8 Rxc8 30.Rxc8 Kxe6 31.Rc7 Rf7 32.Rxf7 Kxf7 33.Kf2 Ke6 34.Ke3 Kd5 35.Kd3 h5 36.h4 Ke5 37.Ke3 Kf5 38.Kf3 g5 39.hxg5 Kxg5 40.Kg3 Kf5 41.Kh4 Kg6 42.g4 hxg4 43.Kxg4 Kf6 44.Kf4 Ke6 45.Ke4 Kd6 46.Kd4 Kc6 47.Kc4 b6 48.a4 a6 49.b3 b5+ bxa4 51.bxa4 Kb6 52.a5+ Kc6 53.Kc4 Kd6 54.Kd4 Game drawn by mutual agreement
