That is insane, having analysis doing dice games. What are you analyzing there? Good decisions are the ways to make Dice games your game ( dont take it literally). I think you are getting confused with this two words, decision and analyzing.
Haha I don't even get it there's nothing to be analyzed when it comes to dice games. Probably he is having hard time on what part of the game he should do analysis. And in color game, it's actually a game of luck so there's no need to apply analysis for it. Well if that is what he is doing, as long as he is earning good amount there, go for it.
