He's an alpha geek and one of the best poker players out there today. His book is good reading, his Ivy league education intriguing. Matt Matros personal website and blog. He gives great tips and is a super nice guy.
I have to also say Daniel Negreanu because he knows what his opponents have without ever seeing their hand and that is unbelievable. His opponents are always in shock when he pulls this on them.
I would say Daniel Negreanu not because he's Canadian but because of his ability to read the other players at the table and use that information to his advantage. However he has not been playing at the level he use to since getting married. It's only a matter of time before he will be back on top of his game again.. I also think that Mike the Mouth one of the top players right now. even though you want to see him lose or blow up. He is one of those players that you love or hate. If you look at what he has done the past 4 years, you would have to say that he is in the top ten of poker players.
