Sacrifice of the Season!?

 

Peter Tart

 

Welcome to the unsound!? world of Camberley Chess Club’s most infamous gambiteer. Those readers looking for an interesting positional game involving long term strategic plans, stop now. It’s tactics all the way, who cares about long term structural pawn weaknesses when the game will be finished within 30 moves!

 

In keeping with my style, lets get stuck into the game.

 

White: Tart, P (131)

Black: Foster, J (158)

Berks Div 2, Camberley C v Newbury, 2nd Nov 04

 

1.  e4                e6

2.  d4                d5

3.  c4!?

 

 

White goes all out with the Diemer-Duhm gambit, not recommended for those of a nervous disposition, just another day at the office for me! Whilst this may appear to be a crazy idea, a score of 7.5/9 with this opening tells its own story, and the loss wasn’t down to the opening either! Don’t get me wrong it is crazy, but it also puts two fingers up at the French Defence player and drags them kicking and screaming out of the comfort of their opening theory. On one occasion my opponent was so shocked they took 30 minutes to make another move!

 

3.  ...                dxe4

4.  Nc3              Bb4

5.  f3?!

 

Interesting, but not whites best continuation, usually white plays Qa4+. It had been a while since I’d played this variation since most players opt for Nf6 instead. White is now hoping for Bxc3, exf3 or Nf6 to transpose back into the main line.

 

5.                  c5!

 

Black doesn’t oblige, and correctly strikes at the centre.

 

6.  a3                cxd4 =

 

This is not the best way of swapping the minor pieces, exchanging with Bxc3+ instead leaves black with an edge. With the chosen move black obviously envisages an advantage once the queens come off due to an extra pawn and superior pawn structure.

 

7.  axb4            dxc3

8.  Qxd8+         Kxd8

9.  bxc3            exf3

10. Nxf3

 

 

10.  ...               f6

 

Maybe Nd7 is marginally better, but this temporarily blocks in the bishop. It comes down to what development plan black chooses to execute. Black may also be worried about the potential of the white knight attacking f7.

 

11.  Be3

 

White develops another piece while threatening to regain the pawn, which would leave white at a slight advantage due to his greater development and space. This fact forces black into yet another pawn move.

 

11.  ...               a6

12.  Bd3

 

Yet more development, this along with whites greater space give just enough compensation for the pawn according to Fritz. Question is which colour would you rather have over the board?

 

12.  ...               e5

 

Yet another pawn move! Paradoxically this is the best move, according to Fritz, and is consistent with black's development plan when playing f6. By now most average club players would probably be getting a bit nervous about blacks lack of development.

 

13.  O-O            Be6

 

 

 

Black stays consistent with the plan of developing the bishop before the queen's knight. White now pulls the rabbit from the hat!

 

14.  Ng5!!

 

Black is forced into a choice he doesn't want to make; move the bishop to safety and drop a rook after Nf7+, defend the bishop with Kd7 (15. Be4 Bxc4 16. Bxb7 fxg5 17. Rfd1+ Kc7 18. Bxa8 Nf6 [+1.9]), or accept the sacrifice.

 

The only other alternative that leaves white better is Nxe5, but this doesn't force black into accepting the sacrifice (14… Kc8 15. Rae1 Ne7 16. Bb6 [+1.2]). While white is better, this line allows black to develop his pieces with the hope of some play. With Ng5 this isn't the case as we shall see.

 

14.  ...               fxg5

15.  Rf8+

 

When considering if to play 14. Ng5, you may be surprised to find that I didn't actually analyse specific lines here, but instead tried to answer the following two questions:

1. How is black going to develop his pieces?

2. What is blacks overall plan?

 

I spent 20 minutes analysing the position that would occur after Rf8+, trying to find half decent answers to these questions, and since I couldn't then I thought it must be worth a try! Take a look yourself and see if you can come up with any reasonable answers. It’s quite tricky, isn’t it? The rook on f8 is a monster, pinning both knights to both rooks!! It’s amazing how one piece has immobilised the vast majority of blacks army.

 

15.  ...               Ke7

 

Fritz rates Kc7 (16. Bxg5 b6 17. Rd1 Bg4 18. Bd8+ Kb7 19. Be4+ Nc6 20. Rd6 Rxd8 21. Rdxd8 Kc7 22. Rxg8 [+1.5])  marginally better than Ke7, but black still has the same development issues.

 

16.  Bc5+          Kd7

 

17.  b5

 

By playing b5 [+2.0] white tightens the net around the black king, cutting off c6 as a flight square. Rd1 and Be2 in either order maybe a slightly better continuation [+2.2] but there's nothing in it. White has a plethora of good moves while black is struggling to find any moves, good or bad!

 

17.  ...               h5?

 

Desperation time, black plans to free the kingside rook via h6, but it's to late to help the situation. Bg4 trying to prevent the rook from going to d1 is the best of a bad bunch!

 

18.  Be4!

 

White clears the d-file and threatens Rd1+ with devastating results. 18. Rd1 is almost as good, black is now at the praying stage. If white plays a couple of inaccurate moves then blacks extra piece may just win through, but of course we're all to good to let that happen!? Black is so hopeless now that the best line Fritz can suggest is to sacrifice both rooks! (18... Nf6 19. Rd1+ Bd5 20. Bf5+ Kc7 21. Rxh8 Nbd7 22. Rxa8 Nxc5 23. bxa6 Nxa6 24. cxd5 Kd6 [+6.2])

 

18.  ...               Bxc4

 

The end is nigh.

 

19.  Rd1+           1-0

 

Black resigns, and as they say all moves lead to mate, or is that roads to Rome. Anyway, 19... Kc7 20. b6#, 19… Ke6 20. Bf5#, 19... Bd5 20. Bf5+ Kc7 21. Rc8#, 19... Bd3 20. Rxd3+ Kc7 21. b6# or 20... Ke6 Bf5#.

 

Personally I like the b6# lines, there's something about delivering mate with a pawn that's satisfying. Every chess players ‘Top 10 things to do before I die‘ should include mating with a pawn, not literally of course!

 

When your team mates ask the eternal question 'Did you win?' and you can reply 'Yes, I mated him with a pawn!'. Now that's something we'd all like the opportunity to say, and I almost got the chance.

 

Sacrifice of the Season Challenge

 

To all club members, let’s see if anyone can come up with a better sacrifice in a match this season.

 

The only entry criteria are:

1. It must work over the board!

2. In hindsight it must be sound.

 

Many a time I’ve heard play say ‘I played a lovely sacrifice, but I lost. I’m sure it was winning. I just couldn’t find the continuation’, well that’s a fat lot of good! Obviously, while 2 is less important than 1, it’s always better to know you played a sound sacrifice.
