Both dozer and sarbox both have good points.

Like dozer said, it's hard to play Ax sooted like we do 22 - 77 because there's ZERO deception when we hit our hand. It's almost impossible to get paid off big enough when we do hit to make it worth limp/calling or flatting.

I play 'em like Sarbox generally suggests. I'm RAISING from the BTN if I decide to play A3s after 2 limpers. It's a perfect blind/limp stealing hand with some value when you hit it. It's a terrible hand to play for value (like we do with small pp's that can hit sets). What do you with A3s on a rainbow A95 flop? It's easy to lose a big pot, and hard win anything but a small one.
