Agreed ! A very impressive move !  -:)

The last problem is probably due to the auto232 connection; the old DOS auto232
had synchronization problems - sometimes even in the middle of the game: either
side had sent a move which had never been received by the other side.

I had observed these effects occasionally.

A unmotivated loss on time could also be due to this problem. If this is right,
then it's definitely NOT a problem of the engine. IMHO, these games should not
have been evaluated.
