Start to reward quick decision making in poker?

I agree with this. Similar to chess where blitz = speed chess is the most fun to play and the most entertaining to watch.

Sure, we all appreciate those moments when players have all the time in the world to tank and come up with great plays but it would be cool to see which players could excel in this more intuitive and raw form of poker.

How to do it? In cash games it could be for example that the ones who are tanking longer, pay bigger share of the rake.

I think many of the amateurs have very good raw instincts for the game and they could do better in these and enjoy them more.
