and a useless stack when you check-fold
I disagree because I've come back to win tourneys on numerous occasions with even shorter stacks.
I'd call preflop and I'd check call the flop. If the flop checks through I shove the turn.
Folding preflop? That would likely make it correct for the cutoff and button to raise very wide, which only means less realized expectation for hero here.
Unless the small blind has 45k or something ridiculous, I think co made a sizing error preflop, which is probably shove or fold territory with 15 big blinds.
