If you have a 'read' CO folds a lot to c-bets I'd fire a barrel.

I'm checking A LOT in these spots though, and firing A LOT in HU situations.

I did c-bet because I noted SB had a 75% folds to cbet, but after the hand I noticed it was only after 38 hands.

In retrospect, I'm thinking this is a check behind.
