Hello all. This is my first post to TwoPlusTwo. I hope I am posting this on the right board, please let me know if I have done this in error. I was hoping to get a line check on a spot in a $40 live tournament ($10 bounties). It is a pretty loose game in general, with several players overlimping.

Important to note:
This hand occurred at the last hand of rebuys - if a player were to bust out during this hand, they had the option to rebuy and do a $10 add-on which would put them at 25k chips.

Hero is UTG+2 with 22k chips at 400/800 blinds (27.5BB)
The HJ has announced that they are going all-in to double up or rebuy!

The Action:
UTG Limps, no read on this guy, stack is roughly starting @ 25k
UTG+1 Limps, loose passive player, stack is 20k
UTG+2 (Hero) Limps with A6
HJ (loose passive) moves all-in for 4500
Folds around to UTG, who flat calls
UTG+1 folds
Hero???

Analysis:
In this spot, I decided to move all in for about 16k more. I thought that HJ could certainly be shoving ATC based on my read of her play and the fact that she seemed ready to rebuy. The UTG limp call seems pretty strong, but he only flat called her shove instead of iso shoving so I thought I had some fold equity there. I was trying to isolate the HJ shove and hunt her $10 bounty and figured that similarly, I would just rebuy and add-on if I busted.

What do you think of my line preflop? I feel like my limp is fine in that spot considering she had announced her action out of turn. Do I fold, flat, or jam once the UTG player flat calls? I don't think folding is very good since I limped to call the HJ shove. Maybe flatting is better to just see a flop with an empty side pot? Should I have just folded pre?

if HJ has announced that they're going all in no matter what then just ship it over the limps, esp with bounties in play and stating that you're gonna rebuy anyways.

+1. Shove it in the 1st place if your intention is to call the HJ shove anyway.
