In one of these videos, he showed the RCostigan-SShankland game from the Philadelphia-San Francisco match. In the position after Black's 30th move, there are eight pieces (no kings, no pawns) all on the g-file. Greg claimed that he had never seen anything like that before in a chess game, and challenged viewers to prove him wrong.
Check and mate, Mr. Commissioner.
I found 24 games that had such a set up on the c-file or f-file. In my video response, also posted on chessvideos.tv, I show how I used the position search dialog box to find these games, and show two of the positions (one from Linares 1991, and the other from a famous USCL player!).
Unfortunately, there's an annoying low hum from the microphone, which you'll have to endure. It was my fourth take doing the video (the first time I messed up the search, the second time the audio didn't record, the third time I had to give first aid to a banged up kid), and I didn't want to do it again!
So, without further ado, here's my response. I hope you enjoy it!
UPDATE: The video got munched in the upload. I'll try and re-upload it tomorrow. Until then, here are the positions.
UPDATE TWO: One more, in response to Shankland's comments, that occurred on a "random" file, after move 30 -- past all the opening theory.
