Why did TwixtBot waste time with |32.s733.t8? Did it think it was losing at that time?

That's a good question. I don't really know. It certainly didn't think it was losing. It does like to play out forcing sequences like that, sort of a horizon effect of sorts I suppose -- if it sees playing down below gets it to +0.600 but that punting for a couple of turns by wasting time with losing ladders or whatever gets it to +0.610 it likes that. I suspect adding a proper transposition table will help somewhat with that.

|32.s7 was a forcing move, so this does not hurt its position. Even Alpha Go Zero will make such moves.
The fact that the bot doesn't even seem to be trying with its White moves indicates to me that it thinks the whole thing is pretty hopeless. It evaluates the position after |31.o13 32.l16 as +0.873.
