fold, UTG+1 raises to 2 BB, fold, MP+1 calls 2 BB, fold, fold, fold, Hero ?

No info on villains, I assume UTG+1 opens semi-wide since it's a freeroll (as I said no info ), MP+1 calling range is obviosly huge. I'm never flat calling here OOP and with 15BB.
I think this is a standard, tight fold with no info? Or is this obvious reshove seeing that there is almost half our stack in the pot already?

If you shove they will call AJ+, any pair and in some rare cases with KQs or KJs
You are behind this range so far.

Flat call, play poker. You can check/jam good boards with fold equity and equity when called

Shoving isn't bad here but with the pot odds you can call in this spot and hopefully get a good multiway pot.

I'd jam in a freeroll cos they turn up with any old rubbish (with the caveat of folding if you're on the bubble)
