Now I can't speak for everyone else, but I am definitly on of the ppl that you speak of raising pot preflop. I have to say that yes sometimes I am attempting to steal; although as part of my playing style I also use this technique to antiginuise someone else into pushing. It really depends on who is still in the hand, how they play, my position, and stack size. I do use this method of raising preflop quite a bit. I believe it puts forth a strong hand strength without having to triple the bb which when you are close to being a shortstack or in the early portions of a tourney or even playing out of position is a great way of not overbetting your stack into bankruptcy. What I have learned is that playing inconsitently works fine for me(thats just me). I think it kind of goes hand in hand with my method of betting someones exact stack amount when bluffing
them out of a hand. =]. Please feel free to explain why you would think this is not a good idea as I am always willing to learn.
