Pocket deuces aren't good at all for this. You're either a huge dog, or a slight favorite. I'd rather be pushing something like 78 and hope that I have 2 live cards.

I see this sort of quote all the time, but 22 is a much better hand than 87s in a shove-fest. For instance, you have roughly 45% and 37% equity, respectively, versus top 25% (when called).

Against a randomn hand then, according to Jasbo:
22 is 50.3% and 87s is 47.9%.

However, people do not normally call with randomn hands.

If they call with any ace or any pair then, according to Eastbay:
22 is 42.9% and 87s is 40.1%.

If they call with any ace, except A6o to A2o, any pair and KQs, KJs, KTs and QJs then, according to Eastbay:

22 is 40.5% and 87s is 37.7%.

I think this confirms that:
a) 22 is normally slightly better than 87s.
b) your opponents' calling ranges are more important to your chances of winning if called.

But remember that if there is a 50% chance they will all fold, your overall winning chances are better than calling all-in with AA!
