Is pushing 3 barrels the key to win money?

[insyder19]

I really wonder and should try it. Like I often notice that if I have an overpair and I raise flop and get called, bet turn and get called, finally bet river and most fold. I am sure sometimes they are on a draw but sometimes fold their top or middle pair.

I wonder if the key in poker often is the will to push even AK high all the way without a fear as long as not reraised. I often hear that the good players are not afraid to get called with AK high as long as they make money by making the opponents fold in the long run.

I also think that I am almost always convinced that someone has an overpair if he keeps pushing all the streets long.

SO is agression the key to win? Because the most are scared to call too much with just one pair?
