All in Preflop with AK...

[badblood44]

There is something to this, especially in race situations.

If you hit your A or K on the flop against the opposition's pair, the flop is an action killer and you win a small pot. If the flop is rags, you most likely need to fold your hand losing a small pot.

If you include the fold equity that pushing with AK grants you, then I think you gain EV with this move in many situations. Basically the fold equity you have puts you ahead in any race.

In scenarios where your M is large-ish, your EV is diminished, and in fact can be negative on such a move. You need to weigh the pot size you are trying to steal against the odds of your opponent holding KK or AA.
