JJs in SB; facing weird line; Squeeze Size?

I think you should top up to 100bb and always play with 100bb stack
Your squeeze is not too small. That is to 15bb and I think even 13bb would be enough.
OTF I think calling is not an option because of the remaining stack sizes. Fold or shove.
CO is a short stacker and looks recreational so maybe he can do this with stupid hands.

I think the problem is that 1) you don't have a full stack 2) you squeeze quite big and 3) you cbet the flop quite big on this board ... These lead to you being committed.
You have to call only 16bb more and then you would end up in a huge pot having less than 30 bb left.
To call profitably OTF you have to win only 10% of the time.

I think CO could have TT, Ah9h or some flush draws. And those sets ofc. But even then we have 2 outs. The more I think about this, the more it starts to look like a shove to me.

Problem on the flop is as well that the shover is raising for less than the original bet and then you can only call. If you bet half pot you don’t have this problem, but I don’t think folding flop is an option on a wet board like this.

1) I think your squeeze size is fine. You are OOP and it's multiway so squeezing potsize is fine imo.
2) Calling is not an option. This is a fold or shove, and because your cbet was quite large (normal is 50% pot in a multiway 3bet pot) and you didnt start with a full stack, I think this is a mandatory shove.

Bet smaller otf so you don't commit the short stack as well as yourself

The size of your flop bet commits you. Betting this size and folding is definetly a mistake. The proper way to handle this situation would be to bet smaller on the flop. Then, it's more read dependent, but I'd be more likely to call and give my stack to the queens, specially if I'm playing sub 100bb. I'd say nh, reload and move on.

Considering a smaller flop bet, MP1 calls, CO shoves, then you reshove, MP1 might be folding his queens as well, considering that he beats only JJ and that there is more combos that beat him. Similar approach when you shove, since MP1 should have more combos that you beat.

Whatch out for your bet sizes to leave you some room for folding if you don't intend to snap call the shove. Here you didn't have much room.
