Pokerstove equations:

Player 1: JTo/JTs 39.5 Equity
Player 2: 22+, A2o+, K9o+, QTo+, JTo+ 60.5 Equity


Player 1: A2-7o/s 44.0
Player 2: Same range as last time 56.0


Even with A2o/s against this range, you have a 42% equity against this range. Now on a very short stack 42% equity is pretty good when you need to double up. This is why a lot of people go all-in when they look at just the lone ace.

On a side note, if you ever find yourself on a very small stack and see one card and it's an ace, don't bother looking at the other card. For 2 reasons:

One, because if people want to play against you, they either A. want to gamble or B. have a bigger ace or a pocket pair.

Two, You really don't give off any tells on whether or not if you have a big ace or not. It's just as likely for you to hold AK as it is A2.
