Ok. I own fritz 11 with a lota opening books and chess engines. That costed me some moola. If you want free chess  Gui like fritz to help you play (Cheating NOT recemended) there is one called arena. http://www.playwitharena.com/

GO to arena downloads. and download arena setup (18.4 mg) it's arena with an opening book, a database of games (Or 3) and a bunch of chess engines. The best chess engine by far is rybka 2.2n2 Which is the latest free rybka. rybka 2.2n2 is only beat by the later versions of rybka so use it for any serious anaylisis. Dragon is also preety good.

This can help you with getting MUCH better.

I agree to an extent. When I analyze my own games I often use the chessbase GUI's option to have Rybka 2.2n(or Rybka 3 if you own it) kibitz. Rybka finds stronger moves however the way Fritz puts numerical analysis into plain english is indispensable to someone(like myself) of a weaker rating looking for concepts in their games over numerical positional analysis.
