A8s in CO-What would you do, 2?

[reecelights]

Stars $5/.50, About 4 hours in.

12th hand at table, sucked out my first one there to double up, but haven't played a hand since. Villian has defended his blind once and lost, stolen once, and doubled up two hands ago with QQ.

Comments on all streets appreciated.
