Party $6: I flopped a set. Now what?

[jskinn04]

When pondering the question at the bottom, don't forget to consider my squeaky tight image and the relatively small size of the preflop pot.

First time preflop raiser had made a raise. I hadn't played a hand to this point.

I just called preflop fearing a big pair or a flip with AK.

I flopped the nuts and I decided to c/r. I thought that c/r-ing could trap a bet from the other caller and that the original raiser might want to go broke if he had AA or KK. I c/r-ed so big to shut a possible flush draw.

I'm not going to say whether or not I doubled up. In retrospect, I think that in the long run, it'll be easier to double all the way up by leading for about 60% of the pot. The downside of leading is that both other people may fold and trapping a c-bet might be lost. The upside is that AA and KK probably won't be able to avoid going broke.

Tell me how you'd play this hand.
