Lyde: This problem should just end after N11 - there is nothing left to do... I also think A4 might be a mistake by the opponent as one can play B13 and I don't see a variation as good as the game anymore? For the same reason I would never play E13 with the timing of the "correct" variation here, instead playing it later...
Sadaharu: Changed the problem entirely as I realised white has a good move to win the game
