After Hikaru Nakamura's recent comments about Garry Kasparov and the nature of their work together, it's not exactly earthshaking news to discover that they have ended their professional relationship.
That's too bad for Nakamura, I think, but if he uses what he learned from Kasparov and puts in the work - at chess rather than poker or online bullet and blitz - he can vindicate his decision. And it's good news for the next talented young player with a sponsor or money to burn. Will Fabiano Caruana or Anish Giri be next?
