I was just looking at software. A review (on ebay) suggested that Fritz 10 (or 11) is much better than Chessmaster because the core engine is better as is the training stuff. They said that Chessmaster was more for beginners while Fritz gets into advanced stuff.
However, Fritz 10 only has about 200 training puzzles, whereas Chess.com's tactics trainer has 34,900. Unless Fritz does some pretty amazing teaching, you'll learn more on this website.
I have a number of questions I hope you folks can answer.
1. Why would I go from the tactics trainer to chessmaster?
2. Which version of chessmaster should I buy?
3. Will the recommended version of chessmaster run under windows vista on a laptop?
4. Why should I get chessmaster?
Well I guess that enough to get me started. Thanks for your help.
