I also was thinking about this one... But why resign and not keep playing the ko? (no large ko threats, I assume?)

shapenaji got it right, he must have some experience :bow:

edit: A2 was played as a ko threat risking the loss of the H10 group. If a bot plays such move it is better to count your liberties trice!
