OK ... I should probably know this BUT I don't. So I'll ask the experts. Situation is 25NL and FR.

How to play overcards? Say, for example, you get A J in MP and choose to limp (I know this will elicit comments about limping but however you get there is what I am trying to convey). Maybe there's 1 - 2 players already in and perhaps 2 more callers will complete preflop.

Flop comes as something like 3, 7, 10 rainbow. If the first 1 - 2 players check, should I be betting 1/2 pot with my overcards? If I check, and one of the following players raises 1/2 pot, do I call?

I have seen situations (and done them myself) where I might have limped in the above hand with A 10 (or K 10 / Q 10 from the BB), and I will toss out a 1/2 PSB and usually get folds from there.
