It's almost always a mistake. By limping, you allow in too many weak hands that can outflop AA. Yes you probably saw examples where it made money. But that is because AA is the strongest starting hand, not because the player limped with it. In fact, the player likely gave up some expected value by limping instead of raising.

@DapPoker I should have clarified an important detail. I am strictly talking MTT strategy. Not cash. It has resounding success vs LAG and Pfish types. 1st to act after a limp, call pre, gives a masterful check raise option post flop to a standard C bet, and the villain may size up due to the disguised strength of the limper. I'm going to try it 3 times. I'll update results.

@joebutters75 it does create a check raise oppurtunity after flop. But just about the same amount of money would be in the pot from limping with AA and also inviting other players in. Seems like the risk is not worth the reward. Your opponent has to hit the flop to continue putting in money after a c-bet followed by a check raise. AA does not come around enough to limp ever except if it's folded around to your button or blind. Good luck though curious of your outcome next 3.

@dmbfan ONLY in those hyper aggressive games where I am sure someone is raising I will -limp with AA. Where I play there is crazy action at say the 5-5 1500 buy-in. Some guys open early position 7X BB and get 6 callers. When that is happening regularly I limp sometimes. Pot is 210 and make it 750 to go.

Never limp with Ace's but don't shove either. You should have a standard raise amount and do that.

First, a sample size of three hands is statistically the same as a sample size of zero hands. If it makes you feel comfortable with your strategy choice, there is some value to that, I suppose. Just know that it is not scientific or conclusive.

But there is a larger point that wasn’t discussed previously, but which should be considered. And that is what limping AA does to your overall strategy. If you are going to limp AA in EP, you have to also limp other hands in EP as well. Otherwise, observant opponents will be cautious when you suddenly decide to limp. So now we have to limp a range of hands. And that range, for the same reason, can’t be all monster hands. You would probably need to include some of the mediocre stuff you typically see limped. Now, if you want to continue thinking about protecting your range, you can’t just fold the crap and re-raise the monsters when somebody bumps it up after your limp. Now you have to establish some frequency for just calling with your aces, and also for re-raising your 87s.

The point is that developing a winning strategy around limping aces might well mean that you have to sacrifice EV in other places in order to spring your ace trap once in a while. And to my earlier point, that is something you can’t know from a three-hand trial.

For me, I agree with the previous poster who said that I should have a standard raise, and do that with all of the hands I deem worthy of opening from a certain position.

I never open limp, so nobody is going to confuse my AA with 22. But there is more value anyway in them confusing my 22 with AA.
