Folly

Remember the quote that the winner in a chess game is the player who makes the next-to-last mistake ? This always seemed hedged a bit by Bronstein's equally wry suggestion that three little mistakes make one big mistake.

In any event, as I indicated in "No Letdown", I believe that when it comes to playing the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+), if my opponent makes a series of small mistakes, and I make a series of smaller mistakes, then eventually I should catch up...

Still, it took a while for me to be at peace with the following game.

perrypawnpusher - lourotors
blitz FICS, 2009

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4


The Blackburne Shilling Gambit.

4.Bxf7+

The Blackburne Shilling Jerome Gambit.

4...Kxf7 5.Nxe5+ Ke8


The King can also go to e6. See "Crime and Punisher".

6.Qh5+ g6 7.Nxg6



7...Nxc2+

As in perrypawnpusher - tiagorom, blitz FICS, 2009, although that game actually took place after this one.

More frequently, Black captures the Knight: 7...hxg6 8.Qxg6+ (8.Qxh8 Nh6 9.Qxd4 Qg5 10.0-0 Bc5 11.Qh8+ Ke7 12.d4 Black resigned, perrypawnpusher - tampajake, FICS, 2009) 8...Ke7 9.Qg5+ Ke8 10.Qe5+ Qe7 11.Qxd4 Bg7 12.Qc4 Kd8 13.Nc3 Nf6 14.0-0 c6 15.d4 d5 16.exd5 Nxd5 17.Nxd5 cxd5 18.Qxd5+ Qd7 19.Bg5+ Kc7 20.Qc5+ Qc6 21.Qxc6+ bxc6 22.c3 Rb8 23.b3 Rh5 24.Bf4+ Kb7 25.Bxb8 Kxb8 26.Rae1 Ba6 27.Re8+ Kc7 28.Rfe1 Bh6 29.R8e5 Rxe5 30.Rxe5 Bd2 31.c4 Bc3 32.Re4 Bb7 33.d5 cxd5 34.cxd5 Bxd5 35.Re7+ Kb6 36.h4 Bf6 37.Rd7 Be6 38.Rd6+ Kc7 39.Rxe6 Black resigned, perrypawnpusher - adamzzzz, blitz FICS, 2009.

I've also seen 7...Nf6 8.Qe5+ Ne6 Black resigned, perrypawnpusher - fintrade, blitz FICS, 2009 (8...Qe7 9.Nxe7 Bxe7 10.Qxd4 d6 11.Nc3 Be6 12.Nd5 c5 13.Nxf6+ Bxf6 14.Qxf6 Rf8 15.Qxe6+ Kd8 16.Qxd6+ Ke8 17.d3 Rd8 18.Qe7 checkmate, perrypawnpusher - patitolo, blitz FICS, 2005)

8.Kd1 Nf6

This may work in analogous situations, but not here: best was 8...hxg6 9.Qxg6+ Ke7 and the position is unclear after 10.d3 or 10.Kxc2. 

9.Qe5+ Be7 10.Nxh8



Squandering an advantage, when the simple 10.Nxe7 Qxe7 11.Qxe7+ Kxe7 12.Kxc2 was available.

White's Knight will be stuck in the corner, just as Black's will in the opposite corner, but the second player will come out a piece ahead.

10...Nxa1 11.d4

It might have been a bit better to go after the enemy Knight immediately with 11.b3, intending Qxa1.

11...d6 12.Qg3

12...Kd7

The King moves to allow the Queen to attack the Knight. Rybka suggested after the game 12...c5 13.d5 Bg4+ 14.Ke1 with a winning advantage for Black. The c-pawn acts as a shield against checks by the White Queen (see the following note) and the Bishop check moves the enemy King away from the Knight's escape square, c2.

13.Nf7

It was time to sue for peace with 13.Qh3+ Ke8 (or 13...Kc6 14.Qc3+, etc.) 14.Qg3. Of course, if Black then plays 14...c5 (or any other number of moves) instead of repeating the position, he is still comfortably ahead.

13...Qf8 14.Ng5 Nh5


Quite unexpectedly, White's Knight has been allowed to escape, and this move loses a piece.

The fact is that the position is quite complicated, as Rybka's post mortem analysis indicates: 14...h6 15.Nh3 Qf7 (hoping to safe the Knight at a1)16.Nc3 b5 17.Nf4 Qc4 18.Qd3 Ng4 (taking aim at White's other Rook) 19.Qxc4 bxc4 20.Nh3 Rb8 21.f3 Nf6 22.Nf4 Ng8 23.Nfd5 which is evaluated as slightly better for Black. The cramp on his Queenside limits White's play.

15.Qg4+ Kd8 16.Qxh5 Qxf2


17.Qe2

I should have simplified with 17.Nf7+ Kd7 18.Qf5+, forcing the exchange of Queens.

17...Qh4

In turn, my opponent missed 17...Qxd4+ which keeps the pot boiling.

This is feeling like the typical Jerome Gambit family game: I'm staying in the game with help from my opponent – a dangerous way to live.

18.Nf3 Qh5 19.Nc3 Bg4


20.b3 d5 21.Nxd5 Bd6 22.Bg5+ Kc8 23.Kd2

Hoping to gather in the Knight at a1, at last, but Black can now play 23...Bxf3 24.Qxf3 Qxg5+ recovering a piece. He will eventually have to give it back with ...Na1xb3, but White's advantage will be made smaller.

23...c6 24.Rxa1

Understandable, as the enemy Knight has been sitting in the corner for over a dozen moves. I also thought that the open file would give me attacking chances against Black's King. It does, although 24.Bf4 was probably more straight forward.

24...cxd5 25.Rc1+ Kd7

White now has a mate in 7 (a better, but still losing choice for Black was 25...Kb8) but of course, it won't play itself.

26.e5

This move is inadequate, as, for starters, it allows 26...Bxf3+ and Black can work his way to a draw.

It also misses 26.Qb5+ Ke6 27.Qxd5+ Kd7 28.Qb5+ Ke6 29.Rc7 Bf4+ 30.Kc2 Kd6 31.Qc5+ Ke6 32.Qe7 mate





analysis diagram





26...Bb4+ 27.Kc2 Rc8+



Black, in turn, wants to use the c-file for attack. It shouldn't work. It does.

28.Kb2 Rxc1 29.Kxc1



It was time for the stranded Bishop to come home with 29.Bxc1. Now it will be lost.

29...Bxf3 30.gxf3

Well beyond my sight was Rybka's suggestion 30.e6+, which would have allowed White to draw after 30...Kc6 31.Qc2+ Kd6 32.Bf4+ Kxe6 33.Qc8+ Kf7 34.gxf3 Qxf3 35.Qxb7+

30...Qxg5+ 31.Kc2


 Sigh. Another pawns vs Bishop endgame, this time with Queens instead of Rooks (see my game against CorH).

33.f4
31...Qg6+ 32.Kb2 Qb6

This hurries the loss, although Rybka's analysis is ultimately just as painful: 33.Qd3 Be7 34.f4 Qh6 35.Qg3 Qg6 36.Qh3+ Kc7 37.f5 Qg1 38.Qc3+ Kb8 39.f6 Qf2+ 40.Kc1 Ba3+ 41.Kd1 Qxh2 42.b4 Qxa2 43.e6 Qb1+ 44.Ke2 Qe4+ 45.Kd1 Qh1+ 46.Ke2 Qg2+ 47.Kd1 Qf1+.

33...Qxd4+ 34.Kb1 Ba3 35.Qg4+ Kc6 36.Qc8+


Resignation would have been okay, instead.

36...Kb6 37.Qc2 Qg1+ White resigned
