Really, you are saying that because of the opposite color bishops in the position. Yet, let me ask you then, what can Black do? Black is down a pawn, and White has a passed pawn on the Queenside, that is why the +1.xx evaluation. So the position is not equal, the assessment is correct, because White can break the pin of f2 easily, and if Black attempts to advance the Kingside pawns, it gets in big trouble, it exposes the King to White pieces. Remember there's enough material on board to mate, Queen, Rook and Bishop. So what you are saying is not correct, because Black needs a good plan, and I cannot see any for Black. Of course, if the Queens are exchanged then the evaluation would be different. Then perhaps, equality would be more correct of assessment. As long as the Queens are on board there's always trouble.
