I decided to run this throuh Pokerstove to see if it looks like +eV to push here. Basically I considerd the 3 villains' calling range to be 99+, some aces, high broadway:

equity (%) win (%) tie (%)
Hand 1: 33.6660 % 31.43% 02.23% { Ah5s }
Hand 2: 66.3340 % 64.10% 02.23% { 99+, A8s+, KJs+, ATo+, KQo }

So we're a 2-1 dog to any callers. These constitue 10% of possible random hands. So you can estimate each villain as 10% likely to call. There are some small odds of more than one caller, and BB's range is probably broader. But for simplicty, let's just say those two factors cancel each other out.

Accrding to my caclulations, pushing here is +t91 eV:

if button calls: (0.033*1040 - 0.067*1040)
if SB calls: +(0.033*1600 - 0.067*1600)
if BB calls: +(0.033*865 - 0.067*865+0)
if no one calls: +(.7*300)

Questions:
1) Did I do the math right?
2) Do the calling ranges seem about right?
3) If so does this mean an automatic push in this situation? Are there any other considerations besides eV?
4) How do you factor in bubble/ITM considerations? Do I need another tool for that?
