Here's an example of a potential river c/r bluff

Example:

200nl 100bb stacks

You call in the sb vs button open from meh reg villain (20/16/2.5)

Flop (6bb pot)

You c/c 5bb's

Turn :Jh: (16bb)

You check, he checks back

River :As: (16bb)

You check, Villain bets 12bb, you c/r to 40bb



This is a decent spot for a c/r bluff. It's possible he might have Ax here or even a slow played Jx type hand, so leading isn't ideal. He might just peel off one bet. But he will probably bet all his air/bluffs on the river A scare card, as well as his value Ax hands.

Villain rarely has a flush here, his best hand is probably some two pair like A2 but more likely AQ type stuff. Hero's hand also really doesn't look like air, esp. after the turn heart peels, so c/r bluff is very credible here.
