Game 1: Engine 1 starts, lets say 1.h3 from it's book (even if the GUI chose that move from the engine 1 book) Game 2: Engine 2 starts 1.h3 - even if that move isn't in it's book. An extreme example, but illustrating my point, that Engine 2 book never gets to "Start". >I don't understand what you mean at all.

This isn't obvious (I know this is not what you >meant, just an observation).

Yes, it would be interesting to learn what these people, with lots of experience (unlike me who played only a couple of Blitz matches when my H732 was new) do about books, book settings etc. I just checked some SSDF posts, & they do not have reversed openings. I didn't expect they would as I believe they always use two computers. Thanks Mike Tina Long > > >Regards, >M.Scheidl
