- This log file is a snapshot of the big logfile.
- In the big logfile I analyzed all positions at 3600 seconds.
- To save some time I used the 2 option as second parameter in the test method.
In this way Crafty stops analyzing if a solution is found 2 times after each
other at different ply's.
- My hardware is Dual 800Mhz with 512Mb RAM.
It seems to be Crafty has found a different solution at ECM.1259.
The score in that position is 2.69.
- Maybe it's a good idea to analyze this position with a few people for a day.
Send me a mail and I we can discust about what's usefull analyze.
- If someone wants to help me with that then send me a mail.
