Who is ahead here? VERY subtle positional advantage. Black to move - position after 31 fxg5 .... (is this perfectly even?) This is the position in game one of Kasparov-Deep Blue. Kasparov went on to win the game. Engine analysis is even but Daniel King (from his book Kasparov vs Deeper Blue) notes that "Kasparov is down a rook for a bishop, but for the moment Black's rooks have little to say. The real pride of White's position is the bishop on b2" [d] 3rr1k1/1p1n4/1qp4p/5PP1/pP2p3/P3N1P1/1BP1b1B1/R1Q4K b - - 0 1 What do your engines say?
