I'd play same way, hoping to fold out some 6x OTR.

I think 3-betting this hand should be considered since we have more opportunity to make nutted hands; and when deep stacked this is what we want. However BB doesn't appear to be a regular since he's not full stacked so I would lean towards calling in this case.

As played I think a lot of villain's range will be Ax heavy OTT so I'd be less inclined to bluff the ace and more inclined to bluff cards like a heart, 2, or 8.

I would make sizing little bit smaller. $0.45 or $0.50. Otherwise wp.

I'd just give up ott, I think that weaker people tend to cbet these flops too often, esp with their giveups. And starting a 2 street bluff vs an nl10 unknown with 6 dirty outs to fold out a pair seems to be too ambitious to me, esp since so huge part of his range now also has a draw.

Once we bet the turn, I guess that we need to bet the river too, but its not a fistpump, he has alot of Ax in his rnage and he is calling with a lot weaker pair some percentage of the time too.

I'd give up on otr. I think our value range kind of goes out the window on this card. That coupled with him hitting it a far amount as well.

I would also give up on the river. He has a lot of Ax that just hit and is never folding. I do barrel any other card though.
