Reg who sat me. This is the first hand of the match so I wasn't sure if he was good yet.

I defend this. It's a lose defend but I'm under the assumption he is going to be 3betting me pretty wide.

I check call this flop. I could also check raise but I think it's better for my whole range if I float here.

When the J pairs and he checks to me I think he could have Ax, 22-88 (if he 3bets these), 9x, even Jx if he is trying to trap me. He could also have overpairs too. I guess what I'm trying to get at is just because he checks here it doesn't necessarily cap his range.

I bet $19 setting up stacks for a river shove. Perhaps $22 would have been a better bet size. What do you guys think about my turn sizing?

I don't think 9x is folding and A high might even decide to look me up here. I have showdown value vs. his underpairs and lose everything else. Is this spot a trivial barrel off vs. an unknown reg?

Thanks!
