Need some guidance on this big slick suited hand

[Gronk]

I'm playing .5/1 on party. I get A /images/graemlins/club.gifK /images/graemlins/club.gif in EP. folded to me and I raise. 3 callers to the flop.

5 /images/graemlins/club.gif8 /images/graemlins/heart.gif4 /images/graemlins/club.gif. Checked to me and I bet. 1 fold and 2 calls.

Turn is K /images/graemlins/diamond.gif. My money card. Checked to me and I bet, LP raises, did he hit the king too? I've got top top and the nut flush draw. EP calls all-in, I reraise. LP caps and I call.

River is 4 /images/graemlins/diamond.gif. I check, EP bets and I call.

I appreciate all comments on this hand as I'm not sure if I played it correctly or not.

.5/1 hands go in micro.

I think it's probably relatively close between reraising and calling sweat it. I wouldn't sweat it, but without a read I'd probably call.
