Not the best spot in the world but I think you have to go broke here.
I don't know too much about how the pokerstars 1-2 game plays, but in the games I play his flop bet means draw or vulnerable made hand a lot.
I raise and call a shove here.

The only thing making me a bit reluctant to put my money in is the fact that he is 24/18. Been better against a 24/22 but whatever.
