yet another tough spot here..
opp is 52/16 and is very passive except on the river where he had 14 AF with a frequency of 56% !!
this lead me to believe that I am ahead here 50% or more when he bets the river due to str8/flush draws etc and potentially pure bluffs as he was maniacish on the river.

my question is, against this type of player do you like a check-call more, and if he was a different player would you prefer a bet-fold in this spot to get calls from hands like A9, 9T, TT, JJ etc if they limp those.
