Emergency Board 10 - Update

MY opponent from Thursday emailed me last night to reveal his sealed move as being one of the two possible moves that lead to a forced mate.
I have therefore resigned the game (after checking, with his permission naturally, that he had correctly sealed the move).
My updated Battersea statistics make grim reading
