Upgrading Fritz?

I have a copy of Fritz 9 and would like to upgrade to Fritz 12- I can't seem to find out whether I need to buy the new version at full price or whether there is an updrade price. If I can upgrade from Fritz 9, can someone please post the link?

Thank You!

I don't believe that ChessBase does upgrades on Fritz. You want a new one, you buy it. If it still works the same, you get a year's membership at PlayChess with any of their major products. But I still have Fritz 8, so I really don't know for sure.

You cannot upgrade from Fritz 9 to 11, so I'm certain that you cannot upgrade to twelve.

Yes, from what I hear, the chief advantage to F12 over any other engine would be the training features and positional evaluation help.

True, someone seeking the ultimate truth for a particularly chess move might want the fastest multiprocessor engine - which is perhaps not Fritz. But that would be a niche use of the tool for the vast majority of players, in my view.

I have sworn off chess purchases of late, but I might reconsider and upgrade my tool set.

Best you can do is risk a torrent, but those things are REAL shifty.  I don't recommend that lol.  Most other chess software companies offer a discount for previous version owners, but Chessbase, as far as I know, does not.  As they say, "It's good to be king".

 LOL, I still use Fritz 8 too.  But it inexplicably analyzes at a tiny fraction of its usual speed sometimes.  Some sort of memory issue with running it under XP I guess.  Plus, I'm sure they have improved the interface, so I'm thinking of upgrading.   

I've noticed a considerable difference in analysis between Hiarcs 12 and 10, and the gap between Fritz 8 and Fritz 12 should be even more significant, especially because Fritz now has much better positional understanding.

Even so, these differences do not manifest themselves all the time. They are evident in certain complex positions. For instance, Fritz 8 and Hiarcs 9 fail the "Shirov Test." Current versions of these engines solve it.
