To sacrifice or not to sacrifice?!
19.01.2010 – A complicated position arose during time trouble in Tomashevsky (2708) vs Fier (2653). The pawn structure leaves us in no doubt: it was a King's Indian. The sacrifice 35...Bxg4 is on the cards, but calculating through all the consequences accurately is hardly possible. What does your intuition tell you?
A) The sacrifice is unsound. Black does not get sufficient compensation.
B) The sacrifice is playable. The position remains balanced.
C) 35...Bxg4 decides the game in Black's favour.
The solution is here, but first ponder over it with a larger version of the diagram.
