Flop bet

[Coelacanth]

Very good live 40 game. Blinds are decent, everyone else is some form of bad, mostly tending towards loose passive with a maniac or two sprinkled in. UTG limps. I limp next in with K[img]/images/graemlins/heart.gif[/img]T[img]/images/graemlins/heart.gif[/img]. Everyone else limps. 9 handed to the flop of Q[img]/images/graemlins/club.gif[/img]Q[img]/images/graemlins/heart.gif[/img]9[img]/images/graemlins/spade.gif[/img], and I bet. A winning player was watching this hand and said he never bets this flop, I admit I didn't give it a huge amount of thought at the time but I'm inclined to bet this very often. He disagrees, but we play pretty differently (I splash around a fair bit more than he does). Family pots are vanishingly rare in this game, so it's not a situation that comes up a lot. Anyways, what's your preferred flop line and why?
