This was an exhibition match at the Arimaa Online Festival on October 30, 2010.
The idea is this: The world number 1 and the world number 2 provide commentary on their own game ("Think Out Loud") while the other player makes his move.
It's a unique opportunity to gain insights into the minds of champions. Beginner or veteran, all can increase their understanding of Arimaa strategy by watching this video. Enjoy!
For more information on the strategic concepts mentioned by the players see the Arimaa wikibook: http://en.wikibooks.org/wiki/Arimaa
