The reason to 3-bet the turn is that there are plenty of hands that can pay you off, despite the fact that you cripple the deck on the flop. I know on the flop it feels like you need to give them a chance to bluff at it, but that's a great turn card, and you should put the pedal to the metal here.

Note that the turn Qs allows hands like JT to and spade draws to now feel they can call a 3rd bet. And of course, with a terrible player in the hand calling, you should 3-bet simply to maximize value against this player.

See, the thing is, there's no way you can gain by continuing the deception here. Anyone good enough to fold a made hand to your 3-bet but call a river bet would have already realized that you have them crushed and folded. However, a player with a straight or flush draw may very well call a turn 3-bet but not a river bet.

So... 3-bet the turn to get 4 big bets instead of 3 out of the calling station, while giving the LAG a chance to go crazy with a draw / bluff / or the miracle 77. You're way past the point where deception can gain you anything.

good luck.
