Anyone who gambles on animals as a sport are not only not intelligent, their inconsiderate asshole who seemingly fine on watching a beautiful horse whos all hocked up run a race, risking injury that OFTEN ends in death. It's sick and cruel and show a major lack of intelligence in my mind.  Sorry as an animal advocate I can't not speak out


As for the other stuff..heck yes it make a big difference Intelligence is needed in games like Poker, Roulette and especially blackjack.  My father was the most intelligent person I'd ever known.  He loved to gamble, but he was very smart about it.  I can't tell you how many blackjack books he read.  He would hate playing with one of my uncles because he was a terrible plyer and would mess up the game.  He's certainly not as smart as my father way.  It matter.
