history: Villain was playing wildly drunk earlier in the night, 4-bet shoving 55 pre over the tightest player at the table (who had AA). Hero had felted him earlier when he led out with a straight in a limped pot and villain check-raised all-in with top pair; I had won a decent sized pot earlier against him by making a fairly tough call when rivering a set on a board that had 4 to broadway. my sense was that he was sobering up and starting to play tighter but he was also chasing money.
Three limpers at 8-handed table, hero is on the button with and raises to $10.
2 call.
Flop is:
Two checks, Hero bets $18, 1 call from EP, 1 fold.
Hero has $650 and EP has $450ish.
Turn:
EP checks, Hero bets $45, EP calls.
River:
Hero bets $100, Villain raises to $275
Is this an easy call because he's repping so few combos of hands, or is it tougher because by the river my hand has to look exactly like an 8 and he can't exactly be value-raising too many worse combos.... he knows I would probably lead a monster on the flop from the straight hand and also knows I have called him down on a scary board before.
