50nl: AQ river decision

[crunchi]

Villain is 31/10 over 80 hands, no other reads.

Pre-flop was an accident.

I think flop and turn play was standard value bets.

On the river I put villain on Ax, Tx or busted draw so i decided to check rather than bet and planned to call a small-mid sized bet. Once he bets big i think we can narrow his range down to Tx or busted draws, however i'm not sure how often he has the draw here, so i fold. Thoughts?
