First of all a big thanks to both of you. Sorry that it was too late for me at 3
a.m. in Germany. I hope that the demonstration showed something to the CC
programmers. I wanted the event because I am sure some people are a bit
surprised how easy such endings are if the solution is known. And to GM the
solution surely is known. But apparently not to programs. Which is just another
proof for their status below GM. As to the mention of Bob, who sees a difference
in the existing rest of time, I am sure that such endings are piece of cake for
a GM, because R endings are the most difficult but also the most frequent and
therefore they have been trained. It's the same with all puzzles, the moment you
know the key, the rest is something of experience and technique. And 8 minutes,
that is more than enough for GM. Of course the proposal Ricardo gave is
worthwhile. Anyway. We see what all should still be done in CC and we should all
have much fun in future. I wished that such demonstrations could be held on a
weekly base.
