Not even sure if check folding is a consideration vs a passive player , do passive players play draws like this on the flop or turn ? and do they shove worse hands on the river when such obvious draws came in ? I think its really likely to be full houses on the river if hes passive and played it this way then jams river.

In game i don't think i can ever make a fold here getting 3/1 even more if btn calls , likely two of you have a flush and one has a full house id wager C/o has the full house. I think you played it fine all the way to the river , then i'm stumped wanting to fold the nut flush getting insane odds. Hows the btn got 6 buy ins aswell ? as he gambled it up or been showing up with the nutts each time ?

Is CO bad enough to play an over pair this way? I know some fish are passive postflop but they go crazy with over pairs. We have $6 behind, I don't mind making it $2 here (as a shove looks like flush or better) and fold if CO comes over the top given your read that they are passive. Yes we are getting sick odds, but if he is really as passive as you think, I can make a exploit-able fold.

Much prefer x/c to leading. Btn can have a worse flush a lot and co will have Over pairs a lot.

I've tried this a couple of times now and this is what I got - eventually. See what you think guys.

Flop: 'Passive postflop' CO bets into 3 and gets two callers. What can we put them on? Not fl dr or str dr, they'd call those not bet them, so 2P, overpair, set.
Turn: Damn if he doesn't bet into us again and pretty big to, that's still 2P, set or overpair, the latter is unlikely given player style, possible but unlikely.

River: I can't see me bet/calling or donk -shoving this river, it's bad. We have the option of putting CO on a str - and as stated that's unlikely or a fh.

I tried to find flushes that they'd do this with and couldn't find one, except maybe, maybe the Ax of ...oh wait we have that and we have the 7c so that cuts straights out a lot to. adn CO wont bet those on flop and turn much.

If I was on the ball I could chk/f this if CO shoves river, if not I call it off like micor station I am wondering how I got here lol.

Chk river for me either way, definitely no bet.
