Well any call virtually guarantees that you're a 2-1 underdog at best, with a decent chance that you're more like a 3.5-1 underdog. As such, there's no difference between pushing 56s and 23o here. You still have plenty of fold equity if you fold utg, the bb, and the sb in the next 2 hands, so I don't think pushing here is good at all. Say you were in late position, and the opportunity came to steal the blinds, it'd be worth it likely, but as UTG you have to dodge too many mine fields to make pushing profitable.

Edit: I just realized it is 6 handed. Even still UTG here is MP, and you probably want to be in the CO or Button to push.
