Think the C-Bet sizing is fine, but as it can be taken as weak, has to be factored in when deciding whether to call.
This was my point...which is why I would bet more...you could be folding to queens here...
So what you are saying is that you bet more so that he knows you have kings and will fold queens.
IMO this is bad on so many levels.
Better to keep your C-bet size consistent. And by keeping it smaller (1/2 to 2/3 pot) you get some advantages.
You will still get folds in most of the instances where a larger bet size would have got a fold.
You will get away cheaper when you have nothing - although you have to accept sometimes he may repop you with a worse nothing.
You are more likely to get repopped lighter when you have something.
As long as you understand how your bet may be perceived, and how this widens your oppos range, you can use this to your benefit.
The only qualifier I would make is that I am a mainly cash player, and don't really do STT's, but I can't imagine it makes a huge difference in this instance.
