I needn't use the debug command in Winboard, I could have simply set the logging
option on, which I did not do as I had stopped testing the previous beta
version. The logging is on while testing a new version.  Thus, one could get all
the info needed from the log... BTW, I can see no 1...Rc8 planned for Black in
your transcript!
