[Merlinius]

Your reasoning is very bad. If you raise preflop and the flop comes A73, everybody who calls a 1/2 potsize bet will also call a 3/4 potsize bet. you think you are able to make them call with weaker hands if you vary your betsizing but this thinking is very flawed. of course, this might work sometimes but it is too important to bet the flop big in all the other cases when your opponents have a hand. assuming, you will bet the turn and river as well the money that went in the pot on the flop will be returned to you doubled or tripled so that this makes up for the very few times your opponents fold on the flop when they would have called a smaller bet.

btw., a lot of players do pick up on this read.
