[Sully]

My first impression was that you absolutely have to bet this river, but the more I think about it, a check and call can't be that bad.

It gives a worse hand a chance to bluff at the pot, and it is an easy fold if the BB reraises. Your hand is good here plenty often enough to call a bet, and by checking and calling, you give your opponents a chance to lose an extra bet if they are behind.
