Bodog 7.50

I hated this hand. Third hand of the tourny; first hand was played at another table; second hand I get AA UTG and raise to 4 BBs, get two callers, bet K-high flop, everyone folds and I show. Neither of the two villains were in previous pot. All stacks ~1500. BLinds 5/10.

CO raises to t25
Button calls
SB folds
Hero calls in BB with K[img]/images/graemlins/club.gif[/img]6[img]/images/graemlins/club.gif[/img] (What do you think?)

Hero??

If you bet, what do you do if you get raised? What do you do on various rivers if you're called?

Who folds preflop?
