River play?

Bet/fold or bet/call? I guess it's a pretty trivial question, but is he raising a hand I can beat?

good play, with the four-to-a-straight out there, he's only raising a hand that can probably beat it. Unless he's a complete 'tard, I'm putting him on at least a straight. Its possible he's raising with three 8's here, but given his prior action I'd say TJs or pocket pair that setted up.

looks good to me, i certainly wouldn't want to call a capped river, so leave it at 2 bets.

If he has JTs, wouldn't he have capped the turn?

Wow that card sucks. I might find a check/call here. Looks like a split, he got there or he's a tard. Got read?
