[quote}I don't recall his exact words. But I understood him to mean that he was going to call any raise that I was going to make.

You're obligated anyway, but if you want to avoid this, call out your exact bet amount/

BTW to all viewers; if his opponent says "I'm calling whatever it is," is he now obligated to call any bet???

So he can't raise at that point? He may only call?
