almost 200 bbs to start the hand, is this river a standard bet/fold? given all our straight blockers and our clubs blocking almost all possible lower flushes it feels like we can't really get herocalled here much at all whereas a hand like AA/KK that c/c'ed a pretty dry looking flop and turned clubs makes a lot of sense. if he got to the river with AA and the nut blocker its a pretty good spot to check shove as well.

checking back a backdoor flush in a 3 bet pot feels really nitty but is valuebetting going to get called by worse often enough to make up for the times we have to bet/fold? the fact that he checked the river instead of leading might weight his range more towards not having a flush though.

Isn't it a little unlikely he have the flush draw, since he called on the flop, maybe some SD is a lot more likely, and you have 3 flush cards.

Maybe do one of those small bets to induce, not sure if they work in plo lol. Or make the bed a size you think a J high flush or a nut straight will do a hero call. And depending on the villain, you prolly fold if showed on.

Just throwing out ideas lol

without knowing more about the villain i'd chk back the river based on holding the 7c and 8c ... if he was c/c with a low flush he's highly likely to have either the 7c or 8c in his hand since those are cards that have straight draws as well. since he can't have those, if he's got a flush it's a strong one so i chk back. now ... if we know villain is like not tricky or trappy and plays his big hands fast then we can bomb this river comfortably
