A9 on the button!!

I usually don't play A9o!! Either in that case:
PokerStars No-Limit Hold'em, $0.02 BB (5 handed) Hand History Converter Tool from FlopTurnRiver.com (Format: FlopTurnRiver)

MP ($2.65)
Hero ($2.59)
SB ($1.51)
BB ($0.61)
UTG ($5.46)

Preflop: Hero is Button with A, 9.
2 folds, Hero raises to $0.07, 1 fold, BB calls $0.05.

Flop: ($0.15) T, 2, 2 (2 players)
BB checks, Hero bets $0.08, BB folds.

Final Pot: $0.23

How do U play Ax with or without position and, wich Ax U play with it's suited??
Thank You for help!

Opening A9 from the button is pretty automatic
