Yet another hand from the 2+2 SNG

[heyrocker]

Everyone who was watching probably knows what hand this is.

4 left, 200/400/50. Stacks are 2620 (dcj311), 4572 (me), 6560 (thomastem), 13248 (wayabvpar). I'm in the BB, looking down at Ah 3s. Folded to thomas in the SB, he raises to 1200. I reraise him to 2400, suspecting a steal (anyone push it in here?) He calls. Flop comes Qs As 4s. Thomas pushes all in, he has me covered by about 2000 or so at this point, he could get called and lose and still pull it off with some luck. I have two choices. Go all in or fold.

Thoughts?
