KK in the SB

PP - $0.50/$1. I get red KK in the small blind. MP, cutoff, and button call. I raise. (I considered checking. Any thoughts?) BB and all the rest call. Flop comes Td 7s 7c. I bet, BB and button call. Turn: 3s. I bet, figuring I'm going to keep firing until someone, say with a 7, raises. Only button calls. River brings the Ks, giving me the boat and leaving a 3 flush on the board. I bet, praying button hit his flush draw and will raise so I can reraise, but he just calls. I show my kings, and he mucks. (Turns out he did make his flush with Ts Qs). Was I too aggressive in continuing to bet? Should I have gone for a checkraise on the flop? Any comments greatly appreciated.


Thanks,


Matt
