White's F6 looks like it might cause trouble? How to win from here? (0.5 Komi, no prisoners)
Rules are Japanese (I think some variations change who wins under chinese rules whatever starting value of komi is given.)
I'd appreciate as much feedback as possible, thanks.
(Update - big thanks to alpha for pointing out my line for white was wrong. I've fixed the starting position.)
