i use a pretty standard range of big cards in position eg no QJo raising UTG even in 6max but i will raise with sooted connectors etc like JTs in any position so that im mixing it up.

Opps figure it out soon enough and start getting outta pots without a monster or become calling stations which soots me just fine.
Thats why c-betting is supposed towork.
If your preflop range is transparent i.e only AJ/AQ/AK etc then your c-bets will be also.
Also too many just go right out and bet, for example with hands like AA on xxxrag flop. If you varied how you play here by c/ring etc then your c-betting again becomes less transparent, effectivly you can get away with a few c/r ace high bluffs if its known youll c/r AA on rag flops.
We can sit and argue the math all day but if your range is wholly predictable as is your betting patterns with certain hands then so will be ur c-bets and how they are perceived post flop.
