Go up one level in this thread


Bob,

Did you add to the Xboard protocol some?  Some of the commands are
things I didn't recognize, like

(To the engine)
>level MOVES1 TIME1 MOVES2 TIME2
>  Set time controls.  This is a more traditional type of time control with
>  a first time control (MOVES1 in TIME1 minutes, then MOVES2 in TIME2 minutes
>  repeated until the game ends.

and

(From the engine)
>time N
>  This is used to tell the interface how much time your engine has left
>  on its clock, typically right after making a move.  This will be turned
>  into an "otim N" command and sent to the other engine  so that it can
>  adjust its value for your remaining time.

All in all, I like this protocol very much.  I was thinking for some time
that perhaps the ICS interface protocol might be the best solution as
this naturally gives us access to a 'judge' - a FICS server running on
third machine.  But that would require TCP/IP to work and would demand the
use of a third machine.  Your solution seems simpler and provides upward
compatibility with ICS servers though the xboard/winboard/robofics interface.
