So I've been pretty spewy/lagtard the whole session , prob raising about 40-50% of hands , which obv isn't a good thing but I'm drunk and having fun , it worked out and i got payed off big on a few hands.
Villian has been playing a lot of pots with me.
Seems pretty loose passive preflop but bets a lot post flop?
What do i do on this river?
Villian has been @ the table since i joined. Vs a weak/tight player earlier who bet weak on the flop/turn i check/raised AI on the river with a busted fd and he folded and i showed only to hopefully set up something in the upcoming hands. Next hand i flopped the goods vs weak/tight and played it the same and took his stack , so Villian in this hand is aware im playing spewy and bluffing and what not.
Do i flat his re raise or shove?
