Yes, the bettor is supposed to show his hand first. In live games though it's very common for either player to just anounce his hand. It's a generally accepted practice and makes the game more light hearted, which is what you want. It's also common for the bettor to just say "I missed" which basically means he has nothing.

Just show your hand and take it down, if the loose player starts to think he's going to have to show his crap hand more often he's going to tighten up, not what you want!
