I don't have Fritz at all, but from my past experience it is better to analyze by yourself without the computer, and than analyze with the computer.
-Shows how you think, and can help correct this
-Shows how you analyze, and how you can avoid making the mistake.
-Of course, it shows you the blunders, inaccuracies, etc made by you and your opponent.
Sorry I wasn't able to help with the technical stuff.
lol.....I have the Fritz package cos I play on playchess.com
Yes I think I will start to use chess.com computer analysed games.
Cheers for the replies.....
The ONLY way to improve is analysing all your games , won, lost or drawn, as extensively as possible, WITHOUT ANY ENGINE AID.
Only after you have analysed them by yourself and made a few conclusions (right or wrong, does not matter at that stage) you can consult a master, or an engine for proofing of your ideas.
In fritz 12 there is a menu called "analysis".You choose this menu,then the option "full analysis" and a window with options opens.You choose the time you want for the analysis and wait until the game is analysed.After that you can save the game with the annotation.
