Tweak dynamic contempt (the birthday patch) Make dynamic contempt weight factor dependent on static contempt so that higher static contempt implies less dynamic contempt and vice versa. For default contempt 24 this is a non-functional change. But tests with contempt 0 shows an elo gain. Also today is my birthday so i have already give to myself a gift with this patch :-)! Further proceedings: in the past we checked for default contempt that it doesn't regress against contempt 0. Now that the later is stronger and the former is the same strength this should be rechecked. Perhaps the default contempt have to be lowered. It would be interesting to get some idea of the impact of this patch outside of the 0-24 contempt range.
