I'm going to have to watch this through to the end... However... Even I could beat a few Grand Masters if I played all 9 gaes at the same time...
The concept would be thus (though this dude is trying to mystify it), you split up the gaes playing some white...some black...
Game one play Black - Playing Grandmaster A
Game 2 play white... - Playing Grandmaster B
Let Grandmaster A make his first move as White, then you make that your first move in Game 2...
When Grandmaster B counters you in Game 2, you let that be your Black Move back in game 1...
You could make it look a little more complicated playing 9 guys... because you could pair off 1 and 6, 2 and 4, 3 and 9, actually play againt 5 (yeah he'll kill you) so on...
Basically the GrandMasters play each other... Chances are good some will actually beat the others...
Ugh... and now I watch
