That's ChestUCI (special mate mode), of course. Normal Chest has no chance, here. >>Jouni > >I am at a loss. Any hints? Without asking Chest, my warmware sees the zugzwang theme here: If white could pass (do null move) black were forced to move the g pawn. Do this 3 times, and we get a6 bxa6 and its over soon. Unfortunately I count more than 31 moves for this complete manoeuvre, so I appear to miss something. Cheers, Heiner
