BB is a 66/19, 3/6 fold to CB, 33 hands

So OTF and OTT he's got a lot of 3's in his range, 22-QQ probably, 45, some hands like A2, K2, and I'm sure there's a bunch of random overcard floats in there, some of which hit OTT like AT KT etc.

His sizing OTR makes me think he hit something? Like 66, 45, 22, 33, 3x. Can we ever consider calling here or are we pretty well dead? Can he show up with bluffs here or random 6x hands?

Thanks

The thing you need to understand hand reading wise is that he probably doesn't have many bluffs when he calls 233. Many of his calls are ace highs that are perfectly content to check the turn. For this reason I think I'd bet small on the turn with 77 for protection and value. Checking doesn't make a lot of sense in terms of setting up profitable situations for the hand given our assessment of his range (it being mostly SD value hands and few bluffs other than 54/65). So long story short I'd probably bet about 16-18 on the turn and follow it up with another bet of around the same size (18-20 prob) on decent rivers. This will get the most value and protection vs 2x/Ax/draws.

The other thing about checking the turn is that it doesn't make a lot of sense unless your plan is to c/f (because as I've reiterated, he has few bluffing hands). All that said, I think the turn is played OK, I'd call such a small bet also. It just would have sucked if he potted it or something.

On the river I'd fold I think. yeah this dude seems crazy but 54 got there, 65/64 has no reason to bluff. He'll have plenty of Tx/3x. The only likely bluffs for him are A4/A5, so you'll need to see a lot of random spaz KJ hands to be able to call a 3/4 pot all in here.

I don't think that he is bluffing. I think that he hit ten on the turn. Maybe he has AT suited, or TT, but I am more than sure that he has AT, because if he has TT he will re-raise the flop.
