Why not fold the turn? You're getting 3:1 odds with only 6 clean outs. As for the river fold, I think it's the right move. What hands could he have that you're beating? His behavior is not consistent with a slowplayed AA, KK, Ax, etc. Maybe a set, but why would he checkraise when the flush draw completes? I put him on a flush and fold.

Bad card I think. I'm gonna call here though, because I think his line says A9, A5, K9, or something like that. I think calling is okay because BTN doesn't have enough behind to repop, and he is the one that I am worried about here.

I check behind a lot. Too many people call with any A.

Turn I fold, you're drawing too thin. It's unlikely, but possible your T isn't even good (although it may be AT which you could then stack).

I don't mind river bet, but easy fold. Everyonce in awhile you'll fold best hand, but not the ~20% you need
