Subject: Null move R=2 vs Null move R=2/3

Following recent discussions re: using R=2 for null move vs. using R=2 near the
tips, and R=3 nearer the root, I ran a little test.

Here's the results of running Francesca R=2 vs Francesca R=2/3 (running for 12
hours, playing blitz, on my little Celeron 500 machine).

Francesca R=2 : 48.2 %
Francesca R=2/3 : 51.8 %

109 games were played.

A small sample, but as I alluded to in earlier postings, R=2/3 might be
*slightly* better for Francesca. Loads more games would be needed to verify this
with any certainty, of course..
