Grunch-

I think the answer is ATC.

His minimum calling hand should be Tx, he has to have a ten more than 33% of the time for the push to be -EV.

I dont like this kind of play at all, why even take the risk I say wait for a better spot.

[mackthefork]

Are you kidding lol, I've seen unknowns call with AK AQ 22+ all kinds here, and this one had something better than that in all likelyhood.

He said it was an unknown, not a calling station.

By the AQ+22+ flush draw,straight draw calling range logic your push range should be something like a 7x or better for value. I don't really buy that, though.

Doing this with 88 is probably +ev.

[C4LL4W4Y]

i'd say 88 or AXdd

I'm trying to figure out how this is profitable, since as a beginner it seems intuitively a bad play to push without having a good hand. I think that this becomes a profitable play because of fold equity right?

When the other play folds you win $11.05 when they have a ten and call you lose $51.10. Are those pot sizes right? I wasn't including the all-in bet for the pot that you win, but I was including all of the money you bet for the pot if you lost. So thats about 1:5. So you need to win this pot more than around 83% of the time. Is that right? I apologize if I'm just completely off.

[huhwhatyousay?]

The EV of this is
(100-x)%[P(51.10)-22.15] + x%(11.05), where P is our pot equity when called, and x is the percentage of times villain folds. We don't always lose when we are called unless we are drawing dead vs. villain's calling range.

its probably easier to just not put crazy moves on unknowns than to calculate equity versus a range of players and subsequent ranges of hands and responses.
