I bet the turn if the turn is the 2 [img]/images/graemlins/club.gif[/img], but I'm not sure if everyone agrees.

Betting the turn when the 9 pairs is a risky proposition. A solid player will just fold his draw most of the time when you bet, but you'll get him bluff very often when he misses the river and you checked behind on the turn. And when he doesn't fold the draw, he probably gets aggressive and forces you to make a tough decision.

This way, it's not even certain betting the turn is best if he does have a draw. Add in the times he has you beat and the times he has a made hand that will fold to a turn bet but call a river bet after the turn got checked through, and checking should be clearly superior.
