While
is huge, I'd like to tenuki, so I find 
questionable. The direction of play of 
seems off too, I think approaching from the bottom is better, as this group is too weak. I think W gets the lead, but 
seems like a serious mistake, the shape is just too bad, and B ends up wiping out W's centre influence and replacing it with B potential, and I don't know what to think any more afterwards.But the highlight for me is the fighting over last few kos, and then move 260. A complicated, but critical sequence in a 0.5 point game. It looks like a small cute endgame problem, but it took me a while to unpick the maze of variations.
I had thought for a while that B seemed to have made a mistake at move 263 in not ending the ko, perhaps B could have won by 1.5 point, but eventually found the correct line (I think!), and found that B did make a mistake, B should have won by 0.5 point.
