I actually think it's a closer decision than people might think. What range of hands would you put the EP and CO on? Keep in mind that my read is very subjective and doesn't absolutely dismiss the possibility of a big hand for either.

you need 26.5% equity to break even

equity (%) win (%) tie (%)
UTG: 35.6176 % 31.27% 04.34% { 99+, AQs+, AQo+ }
Button: 35.8667 % 31.00% 04.87% { TT+, AQs+, AQo+ }
Hero: 28.5157 % 21.38% 07.14% { AKo }

if we remove only AA from CO's range above based on your read, we get...

equity (%) win (%) tie (%)
UTG: 36.7924 % 32.21% 04.58% { 99+, AQs+, AQo+ }
Button: 33.3064 % 28.18% 05.13% { KK-TT, AQs+, AQo+ }
Hero: 29.9012 % 22.38% 07.53% { AKo }

are these fair ranges for both players?
