Hello. Here is a hand from today. Do you lay this down?

Party Poker $25 NL

I am in MP and raise to $2.50 w/
I get 4 callers. The SB BB MP and button.

The flop is

The BB bets $3 into the $10 pot and MP re-raises to $15.

It's to me and I have about $23 left. What do you do?

Push all-in. Not much else you can do with these stack sizes.

As usual I agree with MG, with no reraise preflop its doubtfull someone has a bigger set than you. The situation that really screws you is if one of them has AQ and the other has k/10 which is a possibilty, that said its party, my guess is BB is on a flush draw and MP is playin AQ.
