You found the starting move but the conclusion is quite wrong - there is a whole lot more in this problem ; )

Nice jts! : ) Under the Stones is for itself (in my opinion) an often missed Tesuji but to find it and think the group is dead only to realize there's a Ko in the position really makes this problem a nice but nasty little one : D By the way, the problem is from "The Art of Capturing Stones" and there it is labelled that Black is dead.
