Chessboard: Used once

... by Nakamura and some kid named Carlsen.

The pieces are not mentioned but let us assume they are included.

What would be your highest bid?

I think a Luke McShane board is worth more today

@ trysts 

This board is signed. Nakamura is pretty famous and that Carlsen character used to be rated 1200 and has improved to 2826. He might turn out to be pretty good.

  If I had the major money to burn on a signed chessboard by the H-Bomb and that Magnus kid , believe me I would and I would put it away in a bank vault until I was old and grey and I needed the money. That board will be worth a lot someday and it's good that the money that is made from that is going to a charity of the players' choice  . There still is some good left in the world and rightfully so some of it should come from the chess world.
