Warning: a1 & h8

Chessfriend Welton Vaz has again generously provided a collection of recent (July 2011) Jerome Gambit (and related) games from the FICS database. One game, in particular, holds a warning for those who would meet the Blackburne Shilling Gambit with 4.Bxf7+!?


albgameiro - Alekingg
blitz, FICS, 2011

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

The Blackburne Shilling Gambit.

4.Bxf7+

The Blackburne Shilling Jerome Gambit.

4...Kxf7 5.Nxe5+ Ke8 6.Qh5+ g6 7.Nxg6 Nxc2+

Points of relevance:

1) The Blackburne Shilling Gambit is a fun way to try to bamboozle White with trappy play.

2) The Jerome Gambit treatment of the BSG, 4.Bxf7+, leads to an objectively even game, although White has great practical chances if Black is taken unawares.

3) Black's defense with 5...Ke8 as played in the game, is good, especially if he is happy with a draw; providing that he answers 6.Qh5+ g6 7.Nxg6 with 7...hxg6. See "Incomplete" for a recent examination.

4) The text move for Black risks little, as long as the second player is aware of all of the consequences, and especially if he avoids the punishment for greed by returning to the ...hxg6 line on his next move (if White plays 8.Kd1).

5) The tactical play is more complex than If-you-take-my-Rook-then-I-will-take-your-Rook, requiring some planning (preferrably before the game).

8.Kf1

The wrong direction. 

Correct was 8.Kd1 as in perrypawnpusher - lourotors, blitz, FICS, 2009 (0-1, 37);  perrypawnpusher - robertpthom, blitz, FICS, 2010 (1-0, 32); and perrypawnpusher - ZekeTheWolf, blitz, FICS, 2010 (1-0, 30).

The difference is that after 8.Kd1, 8...Nxa1 leads to mate (see "The Somnambulists"). White gets a bit of an edge after 8.Kd1 Nf6 9.Qe5+ Be7 10.Nxe7 Qxe7 11.Qxe7+ Kxe7 12.Kxc2.

After 8.Kd1 hxg6 9.Qxg6+ Ke7 10.d4 White has threats that Black did not meet in three games in The Database, but 10...Bh6!? seems to hold after 11.Kxc2 or 11.Bg5+, with White's extra pawns balanced by Black's extra piece.

However, in the game, White's King moved away from the marauding Knight.

8...hxg6

Rybka 3 suggests that after 8...Nf6 9.Qe5+ Be7 10.Nxh8 d6 11.Qc3 Nxa1 12.b3 Be6 13.Qxa1 Kd7 14.Qd4 Qxh8 White does not have enough compensation for his missing piece.

The text is a test of White's greed.

9.Qxh8

The players could have arrived at this position through the move order 7...hxg6 8.Qxh8? Nxc2+ 9.Kf1?! When Black, likewise, would be better.

Taking the Black g-pawn with 9.Qxg6+ would have reduced, but not eliminated, Black's advantage, especially if the second player utilized a timely ...Bh6.

9...Nxa1

This is a complicated position, played at blitz speed, so it is not fair to go too hard on either player; but White's a1 Rook wasn't going anywhere, so 9...Kf7 first would have spared Black's King Knight. 

10.Qxg8 Qf6

11.e5

The idea here seems to be 11...Qxe5 12.Qxg6+ and a balanced game.

11...Qa6+

Seeking to free his Knight with ...Qxh2, perhaps, but achieving a whole lot more than that.

12.d3

Maybe White, wishing the Knight at a1 dead and gone for so long, thought it had by now departed.

12...Qxd3+ 13.Ke1 Nc2 checkmate

Theoretical

The Jerome Gambit and its relations are fun "just do it!" openings, but over time they have developed their own "book" and sometimes a line, as the one discussed below, can become "theoretical".

MCMLXXXIII - TheProducer
blitz, FICS, 2010

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 6.Qh5+ g6

This position was reached in the game discussed yesterday (see "Really? Really.") and in 824 other games in the New Year's Database. White scored 60%.

7.Nxg6 Nf6

Not Black's best response (he should take the Knight), but it is enough to complicate the game.

8.Qe5+ Be7

Again, not the best, but, again, plenty messy. Black should try 8...Ne6 9.Nxh8 Bg7 as in perrypawnpusher - xenoglot, blitz, FICS, 2010 (1-0, 37).

White now has several options, only one of which leads to advantage. A little familiarity with the first moves of this opening can save a lot of calculation time and headaches later.

9.Nxh8

Tempting. However, the best chances came with 9.Nxe7, e.g. 9...Nxc2+ 10.Kd1 Ne3+ (or 10...Qxe7 11.Qxe7+ Kxe7 12.Kxc2) 11.dxe3 Qxe7 12.Qxe7+ Kxe7 13.f3 when White is up 2 pawns. 

analysis diagram








9...Nxc2+ 10.Kd1

10...Nxa1

This may be easy to work out with a longer time to think about it, but in blitz it is not as simple. See perrypawnpusher - lourotors, blitz, FICS, 2009 (0-1,37).

Kicking the White Queen with 10...d6 before capturing the Rook was a bit stronger, but in either case Black is better.

11.Nc3

Ignoring the Black Knight in the corner and working on development.

11...Ng4

Half of the moves in this game have been made by the Knights. Look at them!

Sadly, this move ends the game for Black. (Kicking the enemy Queen was a job for the d-pawn.)

12.Qh5+ Kf8 13.Qf7 checkmate

Big Bad Wolf

The other day I ran into a big, bad wolf – a higher-rated player who tried to surprise me with the Blackburne Shilling Gambit. Instead, I surprised him with the Blackburne Shilling Jerome Gambit.


perrypawnpusher - ZekeTheWolf
blitz, FICS, 2010

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 6.Qh5+ g6 7.Nxg6 Nxc2+

Tempting, because it delivers a check, forks White's King and Rook, and generally messes the position up.

Still, 7..hxg6 is better, and after the game Rybka suggested the line: 8.Qxg6+ Ke7 9.Qg5+ Nf6 10.Qc5+ Kf7 11.Qxd4 d5 12.d3 c5 13.Qc3 dxe4 14.dxe4 Qd4 15.Qxd4 cxd4 16.f3 Be6 17.c3

when Black is slightly better, although someone comfortable with the Jerome Gambit would probably be comfortable with the White pieces. 

8.Kd1 Qf6

Played too quickly. Better was 8...Nf6 as in perrypawnpusher - xenoglot, blitz, FICS, 2010 (1-0, 21) and perrypawnpusher - lourotors, blitz, FICS, 2009 (0-1, 37); but not the suicidal 8...Nxa1 9.Nxh8+ Ke7 10.Qe5, checkmate, perrypawnpusher - mbranimir, blitz, FICS, 2009.

9.Nxh8+ Ke7 10.Kxc2

I was surprised when I checked the updated New Year's Database after the game and saw that my opponent had played this line before: 10.Nc3 c6 11.e5 Qxh8 12.Kxc2 Qg7 13.d3 h6 14.Qh4+ Ke8 15.Qh5+ Ke7 16.Bf4 Qxg2 17.Bg3 d6 18.exd6+ Kd8 19.Rae1 Bd7 20.Qf7 Bxd6 21.Qxg8+ Kc7 22.Qxa8 Bxg3 23.hxg3 Qxf2+ 24.Re2 Qxg3 25.Qxa7 Qf3 26.Qa5+ Kc8 27.Qa8+ Kc7 28.Rxh6 Qxe2+ 29.Nxe2 Black resigned, DragonTail - ZekeTheWolf, FICS 2007

Still, the stronger reply that both DragonTail and I overlooked was 10.Qxh7+  as in 10...Qg7 11.Qh4+ Nf6 12.Kxc2 d6 13.Nc3 Be6 14.Re1 Kd7 15.d4 Be7 16.d5 Rxh8 17.dxe6+ Kc8 18.Qf4 Kb8 19.e5 dxe5 20.Rxe5 Bd6 21.Nb5 Bxe5 22.Qxe5 Qg6+ 23.Kb3 Rc8 24.Bf4 Ka8 25.Nxc7+ Rxc7 26.Qxc7 Qe8 27.Rc1 Qxe6+ 28.Kc2 Qc6+ 29.Kd3 Qxc7 30.Bxc7 a5 31.Bxa5 Ka7 32.b4 Nd5 33.Kd4 Nxb4 34.Bxb4, Black forfeited on time, stemplarv - hitijnar, blitz, FICS, 2008.

10...Qxh8

White is ahead the exchange and two pawns, a winning advantage if he can develop and press his attack, while keeping his own King safe.

11.Qg5+ Ke8 12.Nc3 c6 13.f4 Be7 14.Qh5+ Kd8 15.Qf3 Nf6 16.d3 d6

17.Be3 Bg4 18.Qf2 Bd7 19.h3 Kc7 20.g4 a6

Black's last move weakens the b6 square. Perhaps he was preparing to move his Rook without losing his a-pawn. After the game Rybka recommended 20...Be6, instead.

21.g5 Nh5 22.Bb6+

Taking a short break from the Kingside advance to force Black's King to block his Rook.

22...Kc8 23.f5

This pawn sacrifice was not necessary – I could have prepared for this advance with 23.Rhg1 – but the open g-file is useful. 

23...Bxg5 24.Rag1 Bf6 25.Qf3 Ng7

26.Rg2 Bd8

To get rid of the annoying Bishop at b6. Rybka's suggestion shows how difficult Black's position is, as White's Rooks infiltrate along the g-file: 26...Qf8 27.Rhg1 Ne8 28.Rg8 Qe7 29.Qe3 a5 30.Bd4 Kc7 31.Bxf6 Qxf6 32.R1g7.

analysis diagram








 27.Bxd8 Kxd8 28.Rhg1 Kc7

This slip frees up the Rook, but drops the Knight.

29.Rxg7 Rf8 30.Qh5 Kb6 Black resigned

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
