[Sir Winalot]

In this special hand I would pot the flop because it makes my turn shove a little less than the pot (assuming they both call), but by betting 1.6 our turn shove would be a slight overbet. But it's not that important here as IMO the money is going in anyway vs stations.

But to answer your Q, no. I vary my c-bets from 3/4-pot to pot. What I consider when deciding the size is usually how drawy the flop is. If the flop is drawy I make a potsized bet most of the time. If it's dry then there's on draws to punish, and I lose less money to bigger made hands by betting closer to 3/4-pot more often (though I make psb's on dry flops too and vice versa). There are also other situational and read dependent factors I consider but the drawyness is usually the most important to me.
