40/80 half kill hand

[rogue]

Just moved to the main game, so no reads yet.

Hero is the SB with A9o.

EP posts a $60 kill blind. MP calls, button calls, hero calls, BB calls.

Flop: AJ8. (don't remember suits) Hero bets, 2 folds, MP calls, button calls.

Turn: 7. Hero bets, MP raises, button thinks for a long time and calls, Hero ?????
