Deep Fritz 12 v's Fritz 13

HI,

I have Deep Fritz 12 and Fritz 13. How different are the engines? If possible I'd like to run the Deep Fritz 12 engine under Fritz 13 GUI, but I'm unsure if I'd lose out on any new features.

Thanks

fritz 13 is updated with better moves and more imporoved blunder checks

You can use both engines with any GUI. Go in Fritz 13, in the engine window, you can click on Fritz 13 and you'll get a list of engines. Chose the one you want. If it says, in Fritz 13, that the engine is not activated, go in the installation directory and double click on ChessBaseAdminTool.exe (the one that's in the same directory as Fritz 13, DeepFritz 12 should be there, activate it.
