Flop comes 2 [img]/images/graemlins/heart.gif[/img]3 [img]/images/graemlins/heart.gif[/img]K [img]/images/graemlins/club.gif[/img]. He checks, I bet 60 and he CRes to 190. If you flat call, what do you do if turn is a blank, like J [img]/images/graemlins/diamond.gif[/img] and he checks. And he bets pot.
