Throwing Away A Half-Point

Playing the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) against a higher-rated player, I found myself up 2 pawns. I became careful – then careless. I did not play well enough to escape the drawishness of the ending – or poorly enough, either.

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


4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6


7.Qxe5 Qf6


My opponent plays "part" of the Blackburne Defense (see "Half a defense is worse than none at all..." for another example), and then errs.

Curiously, there are 18 games with this position in the updated New Year's Database, with White scoring a lackluster 64%.

Blackburne's Defense called for 7...d6. Whistler's Defense called for 7...Qe7.

8.Qxc5 d6


Black's best is 8...Qe7 9.Qxe7+ Nxe7 when he is simply down two pawns.

An earlier game of mine continued instead: 8...c6 9.Nc3 Nh6 10.0-0 b6 11.Qe3 Ng4 12.Qg3 d6 13.h3 Ne5 14.d4 Nc4 15.b3 Na5 16.Be3 h5 17.f4 h4 18.Qf3 Bb7 19.e5 dxe5 20.fxe5 Qxf3 21.Rxf3+ Ke6 22.Rf6+ Ke7 23.Raf1 Raf8 24.Rxf8 Rxf8 25.Rxf8 Kxf8 26.Bg5 c5 27.d5 Bc8 28.e6 Nb7 29.Ne4 Ke8 30.Kf2 b5 31.c4 bxc4 32.bxc4 Na5 33.Nd6+ Kf8 34.e7+ Kg7 Black resigned, perrypawnpusher - Saveurking, blitz FICS, 2010.

9.Qc3

I was so excited with my good fortune that I leaped to force the exchange of Queens. I should have recalled one of Bill Wall's recent games: 9.Qxc7+ Black resigned, Wall - Cheesepie, Chess.com, 2010

9...c5 10.Qxf6+ Nxf6


Black has very little compensation for his lost pawns. His only hope is to out-play me – which, to my embarassment, he does. This was not the first time Raankh schooled me (see "Kersplat!").

11.Nc3 Be6 12.d3 h6 13.0-0 Rhf8


This should lose another pawn. Perhaps Raankh was trying to open up a line of attack on my King? It all is guesswork, as I didn't even consider the move 14.Bxh6. Careless!

14.f4 Kg7 15.Bd2 d5 16.exd5 Nxd5 17.Nxd5 Bxd5


I should have been at least a tiny bit suspicious that my opponent was being cooperative with my exchange-down-to-the-extra-pawns strategy.

18.Bc3+ Kh7 19.Rae1 Rae8 20.Rxe8 Rxe8


21.Re1

A mistake: the resulting endgame is notoriously drawn, providing that both players understand the strategy involved (we did).

The only "positive" aspect of the move is that losing my extra pawns – plus another one – will not matter, as the game will remain a draw.

21...Rxe1+ 22.Bxe1 Bxa2


Each player will now post his pawns on the same colored squares as his Bishop, and the enemy pawns will be blockaded. My extra pawn is meaningless. So are the next thirty moves.

23.b3

Losing a pawn, but locking up the Queenside.

23...Bb1 24.Bf2 b6 25.d4 cxd4 26.Bxd4 Bxc2 27.b4 Bd3


I still hoped that my opponent would make a mistake.

28.Kf2 g5 29.g3 Kg6 30.Ke3 Bb1 31.Be5 Kf5 32.Bb8 a6 33.Ba7 b5

34.Bb8 Kg4 35.fxg5 hxg5 36.Bc7 Kh3 37.Kf3 g4+ 38.Ke3 Kxh2


39.Kd4 Kh3 40.Kc5 Bf5 41.Kb6 Bc8 42.Kc6 Bf5 43.Kb6 Bc8


Here my opponent offered me a draw. I declined, because I wanted to try one more thing...

44.Kc6 Bf5 45.Kb7 a5 46.bxa5 b4 47.a6 b3 48.Be5 Be4+ 49.Kb8 b2 50.Bxb2 Kxg3


51.Be5+ Kf3 52.a7 g3 53.Bxg3 Kxg3 54.a8Q Bxa8 Draw

Blackburned! #1

He came. He saw. He conquered.

That was J.H. Blackburne in 1885 – see "Flaws (Part I)" and "Flaws (Part II)" – and the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+).

Ever since, the Jerome Gambit Gemeinde has seen the Blackburne Defense – or parts of it, at least.

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


The good old Jerome Gambit. "Sound as a cracked bell," as Geoff Chandler has written.

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6


7.Qxe5

Now 7...Qe7, Whistler's Defense, is very strong, but not well known, while 7...d6, Blackburne's Defense, is not as strong, but much better known. Sort of.

Actually, I frequently run into opponents who play 6...g6 quickly and confidently... and then go into a long think.

7...Qf6


For the record, Amateur - Blackburne, London, 1885 continued: 7...d6 8.Qxh8 Qh4 9.0-0 Nf6 10.c3 Ng4 11.h3 Bxf2+ 12.Kh1 Bf5 13.Qxa8 Qxh3+ 14.gxh3 Bxe4 checkmate.

Fantastic!

My opponent in this game, however, lets me take a two-pawn lead.

8.Qxc5 c6 9.Nc3

9...Nh6


10.0-0 b6 11.Qe3 Ng4 12.Qg3 d6


This looks like an invitation for me to put my "Jerome pawns" into motion.

13.h3 Ne5 14.d4 Nc4 15.b3 Na5


16.Be3

Protecting the pawn at d4, but it is interesting to note that this was not necessary: if White played 16.Bg5 instead, and Black responded 16...Qxd4, 17.Qf4+ would have won a piece (17...Bf5 18.exf5) or allowed a sacrificial attack, say 17...Ke6 18.Nd5.

Some day I would like to find this kind of move during a game, not after it. If 18...cxd5 19.exd5+ Qxd5 White's position is crushing afte 20.Rad1 and 21.Rfe1.

16...h5



Saveurking is not going to give up easily.

17.f4 h4 18.Qf3 Bb7


19.e5 dxe5 20.fxe5 Qxf3 21.Rxf3+ Ke6


My opponent was happy to exchange Queens, but there is more to this position than just attacking the King: I still have two extra pawns, one of them passed; plus better development and open lines.

22.Rf6+ Ke7 23.Raf1 Raf8 24.Rxf8 Rxf8 25.Rxf8 Kxf8


Again, piece exchanges have snuffed out any danger to Black's King, but this is not all that is going on.

My first chess book was Reuben Fine's Chess the Easy Way – available in paperback these days, used, for under $5.00 – and it gave me the idea (rightly or wrongly) that much of chess can be boiled down to: win a pawn, exchange everything else, win the K + P vs K endgame...  

I have missed a lot of exciting chess by following this imagined "guideline," and I have been "bought off" with material too many times to mention; but I am almost always ready to cooperate with my opponents' wishes to "simplify" the position and stifle my attack – if it brings me closer to that fabled winning K + P endgame.

26.Bg5 c5

This move hastens the end. Black could try 26...Bc8 instead, with the idea of pulling his Knight back to b7 and then putting it back into the game via d8 and e6.

27.d5


The pawns will now decide the game.

27...Bc8 28.e6 Nb7 29.Ne4 Ke8 30.Kf2 b5


31.c4 bxc4 32.bxc4 Na5


33.Nd6+ Kf8 34.e7+ Kg7 Black resigned


White will Queen his pawn and deliver mate in a few move moves.
