According to the German ChessBase site: http://www.chessbase.de/ Fritz12 is now available. As we didn't get any recension copy we expect the program to still don't fully understand the rules of chess. The question is now, does it also play Wagner in the background in addition to Beethoven, Bach and Rachmaninov ?
What we can tell you for sure is that with the Fritz 13 interface the menue will be twice as wide, they will once again improve the Alpha-Beta Algorithm and also modern composers wil be included as background music. With version 20 the board will be 2x2 cm all the place will be used by menues ...

Is the 290 draw rule been fixed ?
Does the engine still play with pawns on 1st and 8th rank ?
Does it stil play with multiple kings ?
Do the ChessBase admins still ban/mute people for having the Arena logo in the profile ?
Does the database stil contain high qulaity games with 1-3 moves ?
Does the database still contain games from the future ?
Just a few reasons not to buy it...
The real question is when will be the adapter released that allows you to play the Fritz engines within the Arena GUI ? Or when will Frans Morsch finnaly release the Fritz engine as UCI ?
