In Super System, Doyle says...

[TexRef]

I think that what he is saying is that if he has won a hand, or a few hands in a row, he is going to keep putting the pressure on and come on in the next hand. There is some validity to this, I think... Sometimes when you are winning several hands in a row players do not want to play with you because you are taking down pot after pot and they do not want to be the next victim.

On the flip side, there are going to be some players that play back at you because you have won several in a row... It's up to you to identify this and back off when it happens.

Not sure if it's a rush or what, but sometimes things do just seem to fall your way... When you bluff everyone folds, when they call you have a monster, etc.
