I typed this out, then the weirdest thing happened, and it's gone.
Anyway, here is a little what would you do question, in two parts.
First off, after our tourney game on Friday, 5 of us wanted to play some more so we started a little short handed tourney. T15k in chips, 25/50 blinds, top two pay.
In the first level, someone was already busted. It wasn't a really aggressive game or anything, although it seems like it. One guys had AKs and another had A9. The flop was A9x with two hearts, and it was a bet, raise, re-raise all in, call, with both players trying to protect their hand from the flush.
So, we are now at the second level. Here's the situation:
Hero is OTB with roughly 16k
SB sitting with 13ish
BB with about 15-16ish
and UTG with 30ish (this player is aggressive with the chip lead, and lucky us, he has us all 2-1 this early)
Hero is dealt

and limps in after UTG limps. SB limps in also, and BB checks the option.
Flop:
SB bets 500
BB calls the 500
UTG raises to 4500
What do you do here? Next is what I did, and the second question.
I decided I wanted to raise, try and push out the SB and BB, and get heads up with UTG. I counted out some chips, and decided not to push it all in, but to keep myself a few thousand incase all hell broke loose in the hand.
I raised to 12k
SB moved all in
BB called his all in
UTG re-raised all in
Now, what do you do?
