This game was played last January during the Iranian national championships. Black's opening move makes a clear statement he is not especially interested in a draw. At least not until a lot of blood has been spilled. This position shows Black's 9th move - it is a very aggressive counter directed against White's bishop at c4. Black has several tactical problems: he has a backward d pawn and his black-squared bishop has no scope. One of his knights is undeveloped as well. The focus of the battle is the d5 square.

If White continues Bishop takes Bishop, Black will recapture with his f pawn, and then Black will be able to advance his d pawn and open up lines for his remaining bishop. Black is directly questioning White's 8th move. White chooses to maintain tension by moving his bishop to b3.
