some info about the villain wouldnt hurt, agree!
ofc it could be a good exploitive play against certain types of opponents.
so if villains cbets too much and folds to much against check raise his range at the river looks like maybe 8x, 99+, some turned combo draws + some FDs he didnt fold.
i'd imagine that a riverbet shows some profit, but wouldn't consider it as a vbet.
c/c river could be an option against the right type of opponent
but now considering your (percieved)range and not the type of villain described above:
with just 88 bbs and a 3x open raise do you flat a ton of suited connectors in that spot?
and what about like 77-TT(JJ) and 8x, do you c/r the flop with these holdings?
