Dieter ... congratulations on your result and thanks for the nice recount of
your happenings in Paderborn, enjoyed reading it! More programmers should do
this (maybe they have, haven't read everything yet).

Your endgame with P.Conners reminded me somewhat of the Mate-in-48-Rb6 position
of some weeks ago ... I was convinced you were going to win this :), with your
agressive EGTB handling ... but alas, if this was too deep even for Yace ... I'm
glad my program wasn't in Paderborn ;)

Groetjes,
Paul
