I didn't mean your opponent. You gave this position to demonstrate that humans are not always superior to computers in positional understanding. It obviously depends on the strength of the human player. A Beginner for example is certainly much worse. Your opponent wasn´t strong enough to evaluate this position correctly, but I don't think many >2000 players evaluate such a position as better for black. White has the pair of bishops, black has a weak pawn on d5 and a pretty bad bishop. The only hope for black is to set up a blockade.
