Game 4 - Sozin 6. Bc4
Wheels in motionThe game is annotated in detail below:
After a successful fight back in game 3, going into this round, the score stood at 2-1 to Spassky. Fischer needed to get to 12.5 points to take the title from Spassky. A 12-12 would have ensured the Russian kept the title. In short, Fischer needed to keep winning.
The Fischer-Sozin attack, so named with Bobby's surname due to the ubiquity of use in his games. 6. Bc4 is a very uncompromising stance against the 2...d6 and 5...Nc6 Classical Sicilian set-up.
White develops his minor pieces to very good squares quickly and sets to undermine black's defence quickly, often through a series of sacrifices or using the f4-f5 lever.
Black's position is very solid however and white must always be on his guard against the slow but solid counterplay. If black gets into an ending, the additional central pawn (after 2...cxd4), can often mean Black has a minute but enduring plus.
What can we learn from this game?
- Good development is important but so is a solid defence
- Isolated pawns are rarely a huge asset
- Opposite colour bishops increase the drawing chances significantly
Good development is important but so is a solid defenceSpassky, playing in line with well established theory combined calm defensive pawn moves with a slow and steady development of his minor pieces. After 6. Bc4 e6, black has taken away the potential of the bishop hitting f7, as well as the d5 square against annoying knight jumps.
Spassky also used some nice wing attacks with a6-b5 and the h5 thrust to undermine some of Bobby's control and created some good counterplay
Isolated pawns are rarely a huge assetAfter Fischer's 14. e5, it is actually white who is more hemmed in - the bishop on b3 needs a lot to change before it can become strong and the bishop on d4 is a big pawn defending the lonely e5. Perhaps 14. f5 was better to undermine e6, though after 14...e5 black has little to fear.
The e5 also became an annoying weakness which Fischer eventually had to give up to save his king. Note the activity of the b7 bishop also once the a8-h1 diagonal is opened up.
Opposite colour bishops increase the drawing chances significantlyThe game feels like two stories - in the first part, black had to hold off a decent attack from white relying on a strong pawn structure to keep white's pieces at bay.
After the 14.e5 thrust, it was black with more initiative. In the highest level, players often mitigate risk by exchanging and going into an opposite colour bishop ending which is notoriously drawish! The final position is a dead draw. Neither side can hope to force through a pawn, since their opponent's bishop will cover the advanced squares.
Note how white keeps his pawns on light squares and black on dark squares, so the opposition has a much harder time getting to them!
This made the score 1.5-2.5. Spassky held his lead but the last two games had been 1.5-0.5 to Fischer - had the tide started to turn?
