is almost ready for the Holiday season ... New: 1. 19.07 Crafty Code compiled with /DDETECTDRAW option - IMO , this the fastest solving Crafty ever on the WAC 300 - all 300 positions in 10 seconds on my slow dual 1.7 Ghz 2. Two new personalities - Tal and Botvinnik. With the addtion of these 2 personalities, there are now 28 different personalities, including the default Crafty "standard". 3. Now you when you select a personality, you will receive feedback that the personality is selected. Also, typing "krafty" at the command line will also provide which personality you are engaged with. 4. Modifcation of personality settings to vary the usage of time by personality. For example, the "Fischer" will move faster than the slower, deep thinking "Botvinnik'. 5. All of the previous SE enhancements, including the "delay move" feature that is used whe you are playing a "dumb down personality" it will not move instaneously, but will take the normal time as dictated by the level you have selected. 6. "standard" crafty is usually the strongest and I see no reason why this would be different here based on the WAC300 test results - your mileage may vary. Here are some test results of WAC 300 with different personalities at 10 seconds per move, (unoptimized) Crafty 19.7 SE, dual 1.7 Ghz, mt=2, win2k: Personality Correct Total Nodes Searched --------------------------------------------------------------- 1. standard 300/300 93.9M 2. gm 300/300 96.4M 3. philidor 299/300 93.6M 4. nimzovitch 299/300 98.7M 5. capabalanca 299/300 101.4M 6. byrne 299/300 102.3M 7. fischer 299/300 103.5M 8. stein 299/300 106.6M 9. tal 298/300 108.1M 10. petrosian 297/300 117.3M 11. botvinik 297/300 125.3M 12. expert 252/300 23.4M 14. player 196/300 4.7M 15. fish 30/300 .2M It's not quite ready, as I am currently downloading Intel C++ compiler v 8.0 , that may compile a faster executable. E-mail me with the word "include", if you are new to Crafty SE, All previous users that opted-in will be automactically sent the latest and greatest. Do NOT send me an email if you have previuosly opted in - that will just slow down the process ad I have to manually delete the duplicates. I will post again on CCC, when the final version, optimized Crafty 19.7 is released Happy Holidays! Michael Byrne mailto:mfbyrne_pa@msn.com
