Endgame Problem 32

kb: I was watching a high dan game on KGS and it turned out to be very close: B+0.5. I will give the endgame diagrams in /ActualGame, but I backed the game up to the start of the yose. This was a fighting game and the start of the yose stage turned out to be very latein the game.

White to play. What is the best result - is there a winning way for White? He was certainly the underdog. (Boy, that Generate from SGF feature is very handy.)

By the way, this was a 15-second byoyomi blitz game.

White to play
