Someone who understands EV, finally. Are you a poker player as well? Most people have no idea, yet such a basic concept that can make numbers and gambling so much easier. Good luck to you, although I don't play parlays.. With too many teams variance can be a bitch, but 235 days to try and beat it, so good luck.
A lot of poker players don't actually understand EV, they just use it as a buzz word. Bill Chen definitely has an understanding of it though
