White has taken the hanging bishop, and material balance has been restored. After the dust settles, white has a knight and bishop (and the bishop pair) for a rook and two pawns.

Now, black must see to the protection of the weak f pawn and counter white's active light squared bishop. The move here is 14...Be6. This contains white's bishop, giving it nowhere to go without being taken. If white plays poorly, black may be able to trap the bishop as well. Other moves allow white's bishop to occupy the a2-g8 diagonal first.
