[MLG]

you are assuming that 3-betting wins the pot. It doesnt,it wins it against hands you are beating and bad draws, and wins a bigger about 50% of the time against good draws (since he will push and you will have to call) and loses a bigger pot the small % of the time he has a bigger made hand. There's nothing wrong with winning a nice sized pot, but betting here prevents you from winning a bigger pot the times you have the best hand, it prevents you from increasing the chances you win a nice pot when you are about even money, and it prevents you from saving chips in the off chance you are behind. The negatives clearly outweigh the positive of winning this pot now (the times your bet actually wins the pot).
