The calling station who folds to a c-bet on an ace-high board doesn't have an ace. File that away. He'll keep calling on every other board texture.

Why they do it

Calling stations fold when even they know they're beat. An ace-high board when they don't have an ace is one of those times. The rest of the time - paired boards, low boards, flush draw boards - they're calling because they always call. But ace-high is their kryptonite.

The adjustment

C-bet ace-high boards against calling stations without hesitation. It's one of the few spots where they fold consistently. Every other texture - fire for value.

What it's worth

Knowing which specific boards get folds from a calling station is precision exploitation. This one spot alone adds consistent uncontested pots throughout the session.
