I think the turn is a clear check/raise, I mean what hands beat u, AK and KK he caps w/ preflop in that situation, so A5 and A6, 55 and 66 are ahead of u on the turn, if it's a passive villian I bet out the turn in fear that he may not bet for the checkraise.... w/ that being said since u did not, the river is hands down a call, the raiser is betting w/ so many hands in this situation that u beat, he's betting w/ everything from pp QQ all the way down to 22, he's betting w/ A5, A6, this is a clear call.... against certain opponents who r passive calling stations I would bet out this river and fold to a 3 bet, but since we do not have a read I think we get more out of checking and letting him do the betting for us where he might bluff at it where as he would have folded to a donk bet
