UB $5.50 - Non-Results-Oriented Push Check

Math, please. This cannot possibly be correct. TT is 3:1 over any 2. The bubble is over.

To quote Tigerite, ITM is like a mini-bubble.

If Hero folds, stack sizes look like this:
6420
3030
5520 (Hero) (34.77%)

If Hero calls and wins, stack sizes are
3030
11940 (Hero) (45.95%)

Hero needs to win 75.67% of hands when he "calls the all-in" to break-even. Calling a push of any two with TT doesn't get him there. Is my math off?

I think it is. Check mine and see if it makes sense.

You're ignoring the fact that hero has 20% of the prize pool if he calls and loses. It's a bit complicated here b/c hero has villain covered by 100 chips (and the chip amount adds to 14970), but let's use the OP's numbers.

Possible results:

Hero folds: 34.77% of prize pool, as you calculated.
Hero calls and wins: 45.95% of the prize pool, as you calculated.
Hero calls and loses: (V-11640),(SB-3030),(H-100), Hero has 20.47% of the prize pool. I'm rounding this to 20% for sanity purposes

Hero's total equity from calling is (%win)*(.4595) + (%lose)*(.2).

Since %lose = (1-%win), for calling to break-even,

.3477 = (W)*(.4595) + (1-W)*(.2)
.3477 = (.4595)W -.2W + .2
.1477 = (.2595)W
.5692 = W

So, hero has to win 57% of the time when he calls. If Villain is pushing any 2, we're talking about something like the top 20%: 55+,A7o+,A3s+,KTo+,K8s+,QJo,QTs+ that we need to call. Of course, we need a bit more hand than this, b/c V's not pushing any 2, but we need a bit less than that b/c V will fold to our push fairly often here. Going the other way, unless V is raise/calling all in with about his top 17% (66+,A5s+,K9s+,Q9s+,JTs,ATo+,KTo+,QTo+), we have the necessary equity here. Hopefully this bit of handwaving suffices b/c I think it's pretty clear that if the 57% number is correct, then TT is plenty of hand here.
