At first, you strenuously try to move faster in order to reach a certain increased limit for heavy moves in the game
I myself occasionally try to watch Al Fein's streams, and I can't last more than 10 minutes — watching him spend 10-20 seconds deciding whether to take a pile to the right or below is just dreadfully tedious. And then he complains that +30 seconds isn't enough for him.
Honestly, it's easier to just take a pile diagonally, and use the saved time later for more important decisions.
