Villain wasn't overly loose or tight but seemed to have a good understanding of tourney concepts... I really felt like his range was close to any two because we had just gotten ITM and he obv had a short stack... and the table had been aggro pre, very few spots to push if you were short... but even if he had any two my hand isn't really in great shape and if I lose this pot it puts me into push/ fold mode...

so I was pretty unsure what I should be doing here... I think a fold doesn't hurt obviously but maybe this is a spot to pick up some chips
