Subject: Good Test Position, the "ply 16 rook sac"

This position turns out to be an excellent comparitor ofd chessmaster versions.
My puter is 733 Piii, not overclocked with 512 meg of ram. Tested cm55 and cm6k
using cm default but with select 10, and ttables set to 30. results:
cm55 found mate in 14 at 33 min 45 seconds < about 20 sec into ply 13> and at 20
seconds into ply 13, cm6k still found m n 16 at 58 minutes and 45 seconds.
  My play formula on cm55 found it in 31 min and 30 seconds. Am sure other
programs could see it faster, if anyone does any comparitive tests on their
system, would be interested in the results.  IF cm8000 is as efficient as cm55,
and has 12 ply selectivity, it could maybe see it in 10 minutes or so i think.
  This position seems to be another that begs the question : what is a ply : ?
