No. I'll check #8 for it is the 2nd tournament game. Blitz and rapid are not important for me. But of course I'll give the result of #8 too as it is finished. >Next, recently I have posted the differences between R9 and R10. >Did you miss this? Do you mean the few solution results ? In this case it is not significant if a key move is found in 5 or 30 sec, at least in tourney. >The statistic showed a similar result when I compared R6 with R7, >R7 with R8 and R8 with R9. 10-15% different moves per version. >Now you can argue about this percentage. Too low? Too high? 10-15% would be OK for me. >Personally I think this 10-15% is a fine number. If you for example >get a number of 30% different moves you may strongly wonder how good(?!) >your previous version was :-) This question is always interesting. :-) But of course I'd be proud of how good the actual version is. :-) >I like to keep the good moves Rebel played and to do something about >the bad moves. Feel free to disagree with my opinion on this 30%. Surely >I can produce a R10 which plays 30-40% different moves and still plays >good chess but I assume people want the best Rebel available so they >get the best Rebel as I (as the author) can produce and judge this. I think best comparison will be further tournament games. I'd say if R9 plays over 95% the moves R10 plays strength is not the point to buy Rebel10, but... >Last item, I am a little bit surprised by the question(s).
