Download my victory over Fritz 8 at a hash size of 800 MB here, to load it into your Fritz game console. (Download the .zip file and put the game2.pgn file in a location you can find. Then go to File in Fritz8 and then to Open and Database. When Database loads, go to Open again and find the game2.pgn file. Click on it and it will open in the Database; then load the game). Happy analyzing!
