Pincer was bad in top left probably.
Trying to make a ponnuki also maybe bad because I spent 3 (And then 4) moves in the same corner? Sure, I wanted to see how effective it would be but...
Also, W150 at T11 wasn't a move I considered until after I decided not to capture!
Black t8 was bad because it made his atari, which he didn't do, sente.
L5 and E8 are how badly I give up points when I think I'm ahead. For L5 I was thinking there was some aji with the cut next to the left, but then I could just decide to give up two stones?
The pincer in TL was bad.
