The guy I was heads up with was VPIP 40%+ and he was bluff raising on every street.
I can't believe I couldn't get anything out of him. He probably was scared because I've never checked before!
Anyway, when I knew I wasn't going to showdown I scrambled to click the "automuck" button off and had it done with about 5 seconds to spare. The damn program never gave me the option to show!!!!!!!
It's alright though. No one believed me at the table so I posted here and spammed the hell out of the site for the next few hands.
Good for you.
