xela: Black can't avoid the ko, because white has the throw-in at W8, putting white+circle to work. (I find this a useful heuristic in solving problems: "what is the purpose of that stone? Is there a variation in which it's important?" I'm not sure whether this is a good way of thinking when it comes to playing real games.)
