Yes, I do have the latest upgrade (7,0,0,2)as listed in the properties window when right clicking onto the Fritz 7 engine from the Chessbase engines folder and then selecting the version tab...(For those who are not familiar with checking the version that way) I do not know how reliable engine tournaments are when run on one computer either. Supposedly, Permanent Brain should be turned off, otherwise processing time will be divided. Some engines HOG more processing time than others. However, I firmly believe that Permanent Brain is a necessary part of some programs. Taking that away to give each engine full use of the processing time may affect some programs in a negative way. I have personally found when running an engine tournament, using Deep Junior 6 vs Junior 6 or Fritz 6 on a single processor, with Permanent Brain turned on, (which by the way runs a bit slower than Junior 6 if run on a single processor) that Deep Junior 6 wins most games if Permanent Brain is turned on. Deep Junior 6 is a processing time HOG. When Permanent Brain is turned off the results are quite different. I have not found any drastic increase in playing strength between Fritz 7 and Deep Fritz or Fritz 6. Engine tournaments between Fritz 6 and Fritz 6 Old showed a big difference. The older Fritz 6 service packs required you to type in the URL given to you from an email sent to you from Chessbase, and then downloading that service pack, and then entering a PASSWORD that was given to you for Fritz 6. The same was true for Junior 6, different service pack and different password, but there was no Junior 6 and Junior 6 Old. Only the upgraded version would appear. Why don't the new service packs show the engines as Old and then the newer versions? Whether it be Fritz 6a or Fritz 6e? In the beginning it was Fritz 6 and Fritz 6 Old after the service pack. Then you could make comparisons with one computer. Now the upgrade just goes through. Of course you could always keep the old version in a different folder, have the Fritz 6 programs loaded into TWO different folders so they can each have their own engine folder to choose from, and then run games with TWO separate interfaces with a split screen and manually enter the moves back and forth, with the Permanent Brain feature turned off. That can prove to be very time consuming though. However, most of us are addicted to this game or computers of both, so doing this may not be a problem for many of us. Any other responses on Fritz7 vs Fritz 6 and Deep Fritz would be greatly appreciated. I do not know how Deep Fritz on a Dual Precessor fairs against Fritz 7 on a single processor. Any responses on that would be greatly appreciated as well.
