An alternative would be to have the two interface programs manage the clocks. But it is easier for the engines, which are "in the game" since clocks have to be adjusted at time control boundaries... this is a debatable solution.. > >All in all, I like this protocol very much.

If this is implemented, then any of the above can be used to also play on the server, and then the server can be the ultimate arbiter between the two programs... and since the ICS code is free, we *could* grab that, scale it back, and make an automated test program that would do just this for us... > - Dan
