Black gets the centre, the bishop pair and a pawn for the exchange, you say. But the game is not over yet. If black cannot exploit these advantages, it is going to lose. I have seen several games in which one side sacrificed an exchange and apparently had enough compensation. But the compensation disappeared and only a lost position remained. Your suggestion may still be the best for black but I am not convinced. Regards, Gábor
