C[The rest of the board is jigo. Obviously this is an even position.
Black to play. White can make jigo by mirror go, but is required *not* to mirror on the first move only. (E. g., if Black plays at H15 White cannot reply at M15. White can mirror later.) So if Black makes the best move, White cannot make the best response and Black can win by getting the last play.]
