I flirted unsuccessfully with the two ideas in Game-Tree Pruning by Bjornsson
and Marslands (Information Sciences Vol 122(1) pp23-41), but have not tried
MultiProbCut.

I downloaded Bruno's paper, but when I tried to extract it got only multiple
copies of page 1.    Can anyone suggest a fix?

The paper I downloaded was chessmpc.ps.gz   When I decompress it (using gzip -d)
and open it with KGhostView I seem to get 11 pages but they are page 1.
