Preflop KK, blinds 15-30 about 4 limpers so he raises to 325 total and he gets one caller.
The flop comes k
His opponent only had like 500 left and he checked so now it's to my friend with his trip Kings.
What would have been better here? Check, bet half the pot or put him all in.
My thinking was well it's a pretty connected board(straight possibility and flush draw) and this guy did try to see a cheap flop before. The guy only had like 500 left so there's no point in only betting half the pot because if he's going to call 250 he's going to be playing for all his chips. My friend put him all in for the rest of his chips and the guy folded, what do you think he should hav done?
