I just sat down so I have no specific read, but this table was going crazy before I sat down.

Edit to make the title a little more descriptive.

I did bet, and my opponent flat called. River was the , he checked and I checked behind. He showed X. Grrrr.

how did you check behind if he was last to act?

are you just saying river went check-check?

also, that guy's a total wussy.
