Piece vs Pawns


In the following game I had the typical Jerome Gambit extra pawns vs extra piece imbalance. As my time ran short, I think my opponent tried to push things a bit, and it was then, as he focused upon his own ideas, that my opportunity appeared. 

perrypawnpusher - trmii
blitz, FICS, 2012

1.e4 e5 2.Nf3 Nc6 3.Bc4 h6 




The Semi-Italian opening.

4.O-O Bc5 5.Bxf7+ 

The Semi-Italian Jerome Gambit.

5...Kxf7 6.Nxe5+ Nxe5 7.Qh5+ Ng6 8.Qd5+ Ke8 9.Qxc5 d6 10.Qe3 

10...Ne5 11.f4 

Slightly better might be 11.d4, as in perrypawnpusher - Kotimatka, blitz, FICS, 2009 (1-0, 21) and perrypawnpusher - Eferio, blitz, FICS, 2011 (1-0, 24). 

11...Nc4 12.Qd4 b5 13.Qxg7 Qf6 14.Qxc7 Ne7



White has 4 "extra" pawns for the sacrificed piece, but I was uncomfortable with my Queen's cramped quarters, so I decided to give one back immediately. I could have tried 15.d3, instead.

15.e5 Qe6 16.exd6 Qxd6 17.Qxd6 Nxd6 18.Nc3 Bb7 19.d3 Rg8


The Queens are off the board, but Black has a nice attacking idea on the Kingside.

20.Rf2 Nef5 21.Bd2 Nh4 22.Re1+ Kd7 23.Ne4 Nxe4 24.dxe4 Rae8 25. g3 Ng6 

26.Rfe2 Ba6 27.Bb4 Bb7 28.Rd2+ Kc7 29.e5 Ne7 30.Bxe7 Rxe7 31.Red1 Bc6 

I am sure that my central "Jerome pawns" could advance and act spear-like, but I was a bit short of calculating time and decided to use the pawns as a shield instead. My opponent seemed to be moving quickly now, as if he wanted to take advantage of my time pressure.

32.Kf2 a5 33.Rd6 Rh8 34.R1d3 h5

Attacking the "shield" but overlooking the idea behind my last move.

35.Rc3 Rd8 36.Rcxc6+ Kb7 37.Rxd8 Kxc6 38.Rd6+ Kc5 39.Rh6


39...Kd4 40.Rxh5 b4 41.Ke2 a4 42.Rh6 b3 43.c3+ Kc5 44.a3 Black resigned

The Long and Winding Road

The following game takes its time getting where it's going. In fact, it probably could have taken even longer, if my opponent had not forseen the future and decided to stop travelling.

perrypawnpusher - VGxdys
blitz, FICS, 2011

1.e4 e5 2.Nf3 Nc6 3.Bc4 h6


The Semi-Italian Opening.

4.O-O Bc5 5.Bxf7+


The Semi-Italian Jerome Gambit.

5...Kxf7 6.Nxe5+ Nxe5 7.Qh5+ Ng6 8.Qd5+

Interestingly, Rybka 3 (at a depth of 20 ply) sees this "nudge" as 1/2 pawn better than the immediate capture, 8.Qxc5.

8...Ke8 9.Qxc5 d6 10.Qe3 Nf6



A standard Semi-Italian Jerome Gambit position, although Black has also played 10...Qf6 in perrypawnpusher - saltos, blitz FICS 2009 (1-0, 28); 10...Ne5 in perrypawnpusher - Kotimatka, blitz FICS, 2009 (1-0, 21) and perrypawnpusher - Eferio, blitz, FICS, 2011 (1-0, 24); 10...Qe7 in perrypawnpusher - Macgregr, blitz, FICS, 2010 (1-0, 23); and 10...N8e7 in perrypawnpusher - apinheiro, blitz, FICS, 2010 (1-0, 59), perrypawnpusher - VGxdys, blitz, FICS, 2011 (1-0, 32) and perrypawnpusher - apinheiro, blitz, FICS, 2011 (1-0, 25).

11.f4

Or 11.d4 and then 12.f4 as in perrypawnpusher - KenWhitaker, blitz, FICS, 2010 (1-0, 27).

11...Kf8

Taking the King off of the dangerous e-file, if temporarily putting him on the dangerous f-file. Black's plan is to castle-by-hand, with the King ending up on h7. Instead a center strike with 11...Qe7 12.d3 d5 occurred in perrypawnpusher - LeifPetersen, blitz, FICS, 2010 (1-0, 30).

12.f5 Ne5 13.d4 Nc4



It was probably safer to play 13...Nf7, but who can resist harassing the Queen?

14.Qd3 b5

Oddly similar to our earlier game, referred to above.

15.b3 Nb6 16.Nc3 Kg8 17.Qxb5 a6 18.Qe2 Kh7


White has grabbed a Queenside pawn while Black has castled-by-hand on the Kingside. The game is about even.

19.e5 dxe5 20.dxe5 Nfd5 21.Bb2

Good enough, although with White's forces focusing on the f6 square, 21.Ne4 would have been even better.

21...Re8 22.Rad1 Qg5



This was Black's idea, attacking White's King.

25.Rd2 a5 26.Qf2 Ba6 27.Rfd1 Rad8 28.Rxd8 Rxd8 29.Rxd8 Qxd8


30.Qd4 Qg5 31.e6 Bb7 32.Qf2 Be4 33.f6 gxf6 34.Bxf6 Qc1+


The game has taken on some of the annoying aspects of the typical Jerome Gambit Bishops-of-opposite-colors endgame. Still, I was willing to exchange Queens and try my luck. Too, exchanging Queens was Black's best chance.

35.Qf1 Qe3+ 36.Kh1 Bxc2 37.e7 Bd3

A slip, which should have been punished by 38.e8/Q, winning the Bishop.

38.Qg1 Qe6 39.Bh4 Qf7



40.Qe1 Bb5 41.Qe4+ Kg7

Another slip: White can now check the King and win the Bishop.

My opponent seems to have been a bit too comfortable with his assessment of the endgame as drawish. That made two of us.

42.Qg4+ Kh7 43.Qe4+ Kg8 44.h3


A small idea, but a useful one. With the back-rank checkmate prevented, my Queen can wander more successfully, not just limiting herself to offeres to exchange or checks on the enemy King.

44...Bd7 45.Kh2 Qe8

White's e-pawn is effectively blockaded, his Queenside pawns will not produce a passer on their own, and creating one on the Kingside will expose the White King to plenty of attacks. A win for for me, if it is there, is a long way down the road.

46.Qc4+ Kh7 47.Qxc7 Black resigned


With my King safe, however, my pawns do not have to do it on their own. The Queen will soon pick off Black's a-pawn, and then White's Queenside pawns will begin to advance and assert themselves.

My opponent decided that there was no need to let things go that far.

23.Nxd5 Nxd5 24.Rxd5 Bb7

Sometimes "Simple" is Better

When a player's position becomes difficult, he might seek complications, hoping that his opponent will lose his way, and then the game. In the following fight, however, the alternative strategy of not getting "too fancy" would have brought better results for my opponent.

perrypawnpusher - Eferio
blitz, FICS, 2011

1.e4 e5 2.Nf3 Nc6 3.Bc4 h6


The Semi-Italian Opening.

4.0-0 Bc5 5.Bxf7+

The Semi-Italian Jerome Gambit.

5...Kxf7 6.Nxe5+ Nxe5 7.Qh5+ Ng6


8.Qd5+ Ke8 9.Qxc5 d6 10.Qe3 Ne5


An "in your face" kind of move. In this or similar positions I have faced it twice against Kotimatka (see "Diagnosis: Misplaced Knight" and "Echoes"), twice against mikelars (see "Rumors of My Death" and "Kick Me"), and once against Irhall (see "One Little Pawn").

11.d4 Nc4

Of course 11...Nc4 is not the only way to attack White's Queen. There is 11...Ng4 as in perrypawnpusher - Kotimatka, blitz, FICS, 2009 (1-0, 21)

12.Qd3 Be6


Black weaves a complicated defense for his Knight, avoiding the "simple" 12...Nb6.

13.d5 Ne5

Back again.

14.Qg3 Bd7 15.f4 Bb5


More complications. It was time to give material back and keep the loss to a pawn: 15...Ng4 16.h3 N4f6 17.e5 Kf8 18.exf6 Qxf6.

16.fxe5

Instead, 16.Re1 was good enough for advantage, as in 16...Nf7 17.e5, but I was perfectly happy to fall into Black's combination.

16...Bxf1 17.Qxg7 Qh4


If it were not for the White "Jerome pawn" at e5, Black could have defended with 17....Qf6, etc. Now he has to scare up some kind of counter-play, with the accent upon "scare".

18.Qxh8 Kf8 19.Kxf1 Qxe4


"Best" for Black was probably 19...Qxh2 but it held no promise for long-term survival. 

20.Bxh6+ Kf7 21.Qg7+ Ke8 22.Qxg8+ Kd7 23.Qf7+ Kc8 24.Qe8 checkmate
