I am against a passive guy OOP.I had a notice that this guy once slowplayed KK (call pf and c/c postflop).
WTS 34,W$SD 61,3bet pf 3.So my questions are :

1)Should i conti flop and then give up ?
2)should i not bet that big on turn ? I don 't think this guy would reraise me unless he had a monster.
3)is it a value bet on turn ? i had gutshot also.
4)is it a value bet on river ? or i should play c/c or even c/f ?

Thanks !
