My rationale for betting the turn is this:

If I am beaten with a straight or flush on the turn, my bet will almost certainly be raised. In that case, I can safely fold. If my bet is simply called, then it's fairly safe to assume that I have the best hand, and I am up against flush draws/straight draws/TPTK/etc. There are some problems with this strategy - if one of my opponents has exactly QJ or Q8, I probably trap myself with my betting. QQ, JJ, or 88 may or may not raise my turn bet depending on the player and the nature of the turn card, so there might be trouble there. In general, though, the turn bet lets me know where I'm at. I certainly don't like check/folding; there are twelve bets in the pot and any number of inferior hands can bet even a completely unimproved turn.

Anyone else have any thoughts on this hand?
