My onlu read was that he had won a few pots w/o SD, and that he was fairly aggro. I figured he had been stealing a little, and figured that he could float. I wasn't really thrilled, but tank called. Thoughts?

tbh i feel like it would be optimistic to think that the villain would float a 3way limp pot OOP. i think it's more likely that he slowplayed a strong hand postflop than him bluffing because of his line of just calling twice and betting 80% on the river.

usually in these stakes unless you've seen him make a 80% bet bluff on the river in this similar spot i would insta mucked. fwiw you're basically bluffcatching in this spot however if you think he's capable of betting a busted FD or truly just stealing with nothing i would w/e call but again you need solid evidence to make this read.

also, on the Jc turn why did you decide to bet? what worst hands do you think are calling you in this spot and what hands are you making fold? imo this puts you in a tough spot by betting because like you said since villain is fairly aggro he could easily get you off your 10s because there are a lot of horrible river cards for us. i think it would have been better to check/call and re-evaluate on the river rather than bet turn and then check river.
