Hi,
Last Friday (7th January 2005) I started PM on a material-only search from the
starting position. This was in response to a request from Duncan Roberts:

On Saturday 8th, I posted a progress report:

I was hopeful that PM would finish 35 plies over the weekend, but it didn't
happen. When I got up this morning, there had been no progress since Saturday
afternoon and I didn't want to leave my PC on all day. PM had had 43 hours since
it finished ply 34, but although it was still burning CPU time, there was no
more output. The last I heard from PM was:

I'm posting this output purely for completeness. The node counts overflowed on
ply 31 and the PVs are probably pretty nonsensical.
