Will,

I would always play Axs from any position if the game is sufficiently loose and passive. If there are a lot of preflop raises, or if there are only 2-4 people seeing flops, you can lay it down in EP.

Yes, you're playing it primarily for flush value (it only makes one straight). If you flop top pair with no draws, either bet out or go for a check raise if you think you'll get a bet out of late position. A lot of times your hand will hold up. If there's a ton of aggression, you can fold TPNK pretty safely.

In summation, like a lot of things, the answer is "it depends." Post a specific A2s hand to get some more detailed criticism.

Hope this was helpful,
