Try "The Week In Chess", there is a pgn downloadable file for each round and an "all" database. Its at http://www.chesscenter.com/twic/twic.html
the Chess Olympiad games

I would probably wait a week or so for Mark Crowther (TWIC editor) to make sure the gamescores are valid. There have been some issues with the pgn files at the olympiad website. I know it was causing him headaches early on.
I would like to play through all the chess Olympiad games that were played this year, but I am not sure where to find them. Can anyone tell me? I am not looking for mere collections of some of the games such as on chessgames.com, but the entire set of recorded games. PLEASE HELP ME!
