First of all I'd like to say what a great site!
I've been playing a couple of months now and this site probably has the best community forum out there.

My first question is how do people play when they flop the nuts?

For example, suppose you have AK and the flop comes AAK and are first to act with one other player.
Obviously you are hoping your opponent has the other A or a K so you check. If they bet back at you do you simply call or raise?
Personally I call but not straight away as I believe the opponent will smell "Trap". Instead I think for a few seconds then call. Do you think this can make a difference?

How do other people play this? Sorry if this seems like an obvious play but I suppose some people could play it differently.
