user7693: I was just looking for the best move in the position (White to move).
And I thought that capturing the bishop in green square would be the best as it controls 
the open a8-h1 diagonal ,but the engine preferred the bishop in red square with an advantage over 2 points in its evaluation,
I am unable to see the reason (tactical or strategic)
 for this behavior.  


user291: 1.Bxb2 and you're up a rook for a pawn.
1.Qxd1 Bxe5 and you're only up the exchange (rook vs bishop) for a pawn.
