I'm a tight player and in EP I usually don't limp in with less than ATs, however I'm confused that SSH advocates limping in with A2s. Are we playing this mainly for flush/straight value? Since a majority of the time an Ace hit the boards you will be outkicked or worse.

So how would we play this when we hit the ace? What do we do when we hit the ace with a flush draw NOT of our suit is on the board. (Assume there are 3-4 other players in the hand and 2 of them are rocks while the other two are calling stations.)
