River:(11.25BB) 9 [img]/images/graemlins/spade.gif[/img]
Hero checks, Villain bets, Hero is at least counterfied and folds?

villain seemed to be raising light (preflop), makes alot of action at this table (the table was like 35/17/0.9) and showed down the good ones.
i just wanna check if i played this one right.
defending with A8s is correct. i dont reraise b/c he will cap with a very huge range.
flop: this flop could easily missed him, my hand is vulnerable --> CR. he 3 bets me and i call to reevaluate on the turn.
turn: no draw came in and i improved to 2 pair --> easy CR, right? after he 3bets me i want to show this down cheaply and call.
river: my two pair gets counterfied and the FD arrived easy fold?
