Obviously a bad move for white. But how can black take the best advantage of it?

Hint: show I played Be2 to get the rook, but that’s not a good move. More material can be won.

Solution: show Threaten a fork on e2 with the knight. The white knight can cover the spot for a while, but the black a and b pawns can chase the white bishop for a bit before they threaten that knight.

Solution: show Fork the queen and the bishop. Either the queen gives up defending the bishop, or it tries to defend it. In the latter case, use the bishops.

So I chased his knight around for a bit, until he decided to interrupt the chase with a tempo.

Solution: show Move the king away. Then black has two problems: The knight that is still attacked, and a trappable bishop. Black can only save one.
