What will be new?
Fritz 18 chess release date?

Thank you but I still don't understand why they sell it without the gui of chessbase
they sell it with the GUI. otherwise you can't use it

Gabilevi5: Because then they don't have to share the profit with ChessBase, that's obvious. It is assumed that the buyer already has some custom interface where he can easily install the engine. It's so much more profitable, believe me. With ChessBase you get an engine, an interface and a lot of unnecessary ballast (a mediocre library, a database of games and some lessons) and you also only get three installations, if one of the three computers crashes you are out of luck after reinstallation - the only plus is the playchess entry, but they cut that down to just half a year 10 years ago.

You get also a glimpse of the Fritz 18 experience by playing Fritz Online:

Last good Fritz is 11/Deep Rybka 3. Whitout Ribbon.
I have Fritz6 and Fritz16. And most of time using Fritz6 due to it's simple user friendly interface.
For my needs I do not see any advantage of 16th comparing to 6th one.

CB already removed F17 from shop, it means 18th version is about to come. They must have good reason for removing old versions from shop. I would rather prefer to buy F10, for example, than F17 if available so.

a) Fritz 6 does not support UCI engines. Only WB engines can be run there, but they often crashed anyway. Fritz 8 was the first to support the UCI format, but it didn't work quite right and you had to update the uci.dll library on Chessbase. They deleted the old stuff there though, so you'd have to search the site archives. In version 9 it was no longer a problem.
b) I have the original installers of versions 8,10,11,12... I haven't installed the first one for a long time, so it's not sure if the drive will still read it. But only single, not Deep. You would have to find the serial somewhere... And again, there's the hassle with updates, since they deleted them at ChessBase. I had the feeling at the time that they were releasing it with errors on purpose, so that during updates they would have some chance to detect possible pirates, When we in the Czech Republic say "German company", we take it as a sign of quality. But in ChessBase there is probably not a very good output control when each version eventually needs maybe 20 updates. Another Czech half-joke is "Because I know what kind of engineer I am, I'm afraid to go to the doctor". Maybe even ChessBase programmers should be afraid of that.
Dragon Komodo is just the program itself with support for the UCI standard. Theoretically it can be used in a DOS window, but you can run it in any interface that supports the UCI standard - Chessbase from Fritz 8 onwards, Arena, Aquarium, Shredder, old Lokasoft and many others. If you don't have any and don't want to buy any commercial ones, try Arena for playing and SCID for database purposes. There may be some free ones that are better, but I use Fish 3 (Fritz 11) from ChessBase and have no reason to change.
