According to latest Chessmaster (The King 3.33) after the blunder 12...Qxe5
white is already better :

Instead, TheKing suggest 12...Nb4 with black advantage :

conclusion : positions with trapped knight who took rook in the corner are hard
to master, most of amateur engine will blunber in such position.
