YES I have Fritz 12 which retails for about $50.00 and if I knew what I did now I would've stuck with Fritz 10. Any stronger engines are irrelevant to players in your class (or mine) but you can add the following FREE engines: Stockfish, Houdini & Firebird; Houdini is a stronger engine than Fritz's.
You got a great deal!
I went to Target today for errands and noticed Fritz Grandmaster 11 for 10 dollars, I was thinking about buying Fritz for game analysis and whatever other features I could figure out, so I basically impulse bought this since it was just $10 even though I didn't research it.
I'm guessing it obviously isn't as strong an engine as the more expensive Fritz on the chessbase website, but I'm wondering if for a beginner player like me this will be good enough for awhile or is it lacking alot of useful features or strength? Doesn't seem to be alot of information about it online.
