A simple way to use a chess engine to improve is to play against a human at a time control where you can really think about your moves and take notes about all the variations you considered, then analyze the game with Fritz to see what you missed (for the moves played and the moves not played!). Fritz is superb at tactics but only so-so at openings, endgames, or positional play. Identify your mistakes and focus your studies in those areas.
A more common way to use a chess engine and gain nothing from it is to play quickly without thinking, fire up Fritz, then say "Oh yeah, that was my blunder!" and move on.
"When inputting a game ... what is the easiest way to do it?"
In any chess.com game (except live chess) click on the "Moves" tab and you should see a "Save as PGN" option which is quite handy! :)
I am trying to use Fritz 10 to help my chess. Particularly to analyze games. I find the manual that comes with the disc to be of little help and the interface hard to deal with. Can any experienced players let me know how they use Fritz and any links to good info on how to get the most out of the program.
Two things in particular I could use help with. When inputting a game for the engine to analyze what is the easiest way to do it? I end up starting a new game, dragging the pieces to replicate the game I just played. Of course the engine wants to make its own moves and I endlessly take back and force moves to get in the correct data. Is there a way to download the .pgn file from chess.com and just load into Fritz and let it do its thing?
