Proclomation to all CM8 fans Reply to John Merlino, Albert Silver and all other CM8 fans: All of you have in some or other way right. I do not claim that my settings [CM8_Utzinger] are the best ever possible. In the meantime I have stopped testing them. Below the latest results: RESULTS CM8_Utzinger with kostick.obk Standings per 1st May 2001 Settings Style: A/D=-10; SoP=100; Ra=0; MDS=99; SS=8; CoD=0, TT=64, P=on Positional: MP=0, CoC=110; Mob=125; KS=150; PP=110; PW=100 Material: own Q=9.2; opp Q=9; own R=5.2; opp R=5; own B=3.2; opp B=3; K=3; P=1 Download address for kostick.obk = http://members.aol.com/br5an/cmtourn.zip CM8_Utzinger (time control 40/40) - vs AnMon 5.10 [8.5-1.5] score 85 % - vs Chess Tiger 13 [6-4] score 60 % - vs Chess Tiger 14 [3-7] score 30 % - vs Fritz6b [5.5-4.5] score 55 % - vs Gambit Tiger 1.0 [8-2] score 80 % - vs Gambit Tiger 2.0 [3.5-6.5] score 35 % - vs Gandalf 4.32h [5.5-4.5] score 55 % - vs Hiarcs 7.32 [9-1] score 90 % - vs Junior6a [6-4] score 60 % - vs LG2000v3 [2.5-0.5] score 83 % - vs Nimzo 7.32 [5.5-4.5] score 55 % - vs Shredder 4.0 [5-5] score 50 % - vs Shredder 5.0 [1.5-8.5] score 15 % - vs Yace 0.99 [8-5] score 61 % - vs Zchess 2.22 [7-3] score 70 % Total 146 games, 84.5-61.5 in favour of CM8_Utzinger, Score 58 % Also have I tested other settings, for example the CM_8555. The results obtained so far are as follows: RESULTS CM_8555 with andy.obk Standings per 1st May 2001 Settings CM_8555 (Andreas Stauche) Style: A/D=-5; SoP=100; Ra=0; MDS=99; SS=12; CoD=0, TT=64, P=on Positional: MP=5, CoC=100; Mob=103; KS=170; PP=100; PW=125 Material: Q=10; R=5.5; B=3.5; K=3.3; P=1 Download address for andy.obk = none / CM_8555 (time control 40/40) - vs Chess Tiger 14.0 [2.5-7.5] score 25 % - vs Gambit Tiger 1.0 [5-5] score 50 % - vs Gambit Tiger 2.0 [4-6] score 40 % - vs Gandalf 4.32h [3.5-6.5] score 35 % - vs Hiarcs 7.32 [5.5-4.5] score 55 % - vs Shredder 5 [1-4] score 20 % - vs Yace 0.99 [7.5-2.5] score 75 % - Zchess 2.22 [8.5-1.5] socre 85 % Total 75 games / 37.5-37.5 equality / score 50 % Though these results are in no way bad it looks as if Shredder5 is the most unpleasant opponent for any Chessmaster version. So I am going to concentrate on other [improved]settings that will put much more resistance to the computer world champion. You will have noticed that I do never play CM8_default vs CM8_Utzinger or similar matches between the various CM8_personalities. It is my deepest conviction that such trials are more or less a waste of time. At first I have made this too but soon recognized that whatever settings are used vs other top programs, the supposed best CM8_setting at a given time control had [like CM8_default] not much chances against Junior6a or most other top programs. Furthermore I have investigated about 150 test positions with six CM8_settings [CM8 default, and 5 others, no Chessmaster.CMP already defined in CM8] only to see that they all were close together. In any case: with these tests it was simply not possible to define the best CM8_setting. And funny, Chessmaster_8000 default took second/third place in these tests, the same CM8 which does not succeed in the expected manner against other top programs. All these tests and trials confirmed to me that it is somewhat useless to find the top CM8_setting by let different CM8_personalities playing each other. And frankly spoken, who in the chess world is interested in knowing that [let's say as an example] the CM8_Titan [nothing against you Graham!] wins most of the time against any other Chessmaster 8000 personality. Such a statement does not bring anything if the same CM8_personality does not obtain fairly good results [total at least 50 %] against other top programs like ChessTiger14, Crafty, Fritz6, GambitTiger2, Gandalf432h, Hiarcs732, Nimzo732, Shredder5 and so on. Therefore my honest wish to all CM8-fans: start testing your settings exclusively against other top programs and if possible do not play Blitz games. As in the real chess world, nobody cares much about who is the world champion at Blitz. And do not forget to publish your results and your settings. I am quite sure: Chessmaster 8000 is a good program and someone will find a setting that makes the CM8 very strong, even compared with the high level of the best chess programs in the world. And finally, it is already now clear to me that the CM8_Utzinger settings can be improved, there must be something even better. I would encourage all of you to participate knowing that all this is a very time consuming matter. You can't expect that other people are doing your work if your CM8_personality has played two good games against another program. You need a lot of games against different programs and if possible two computers in order to make best use of the autoplayer. But the time is well invested, then ... perhaps, who knows, the best CM8_setting may be yours!! Kind regards Kurt [E-mails, results, games are welcome]
