:-) . But this is an interesting point to discuss IMHO before cct-5 starts - all
the suggestions made so far wouldn't address this problem at all and maybe it is
not possible. It is impossible to know _why_ a disconnection happens at ICC. It
could have been simply coincidence ..

Another theoretical example to not stick to your game too much. Let's say you
have set up your engine with a subset of the 5 men tablebases only and your
engine has no special knowledge on how to deal with this situation . Game
reaches KRPKR which you have but you don't have the promotion sets . Your engine
advances the pawn to seventh rank and you suddenly realize it will never promote
.. - it would require good sportsmanship to not hit the disconnection button "by
accident", wouldn't it?
