Exactly, I can not understand the move 46...g2? from the GM at all. I think that much weaker players (who are maybe not able to get into such a position) would play Bxg4 quickly. If white sacrifices the piece he has still the bad bishop at e2, is a piece down and has no immediate threats. >I do not think that engines do not have a clue here. I didn´t say all engines do not have a clue. Fruit obviously has better evaluation for this position.
