If you could point to one thing that all good poker players have in common, it would be a firm grasp on the mathematics involved in poker. No matter the player, no matter the situation, a good player always has an idea of the pot size, the bet relative to the pot, the bet relative to his stack and his opponents, and much, much more. There are a lot of pros who say they aren't good at math, I think Helmuth is one of those. However, they might not have a degree in math like Chris Ferguson, but they still incorporated math heavily into their decision. In my opinion, math is the basis for any type of poker game. Although there is a lot that goes into the game of poker, I think math is the most significant part of that equation....
