To those who requested it. If interested, please email me at mfbyrne@msn.com.
Some test results with final version - to be released tonight - (some of these
problems are easy by design - if I screw an easy problem - than I made major
mistake).
WAC141 - is the only disappointment - although it sees the Qxf4 move right away
- it doesn;t see mate for almost two minutes.
CCC001 and CCC005 are very tough for standard Crafty 17.14
