.SH TIME CONTROLS
.PP
If one argument is given, it is the search time per move in
[minutes:]seconds.
So
-.B gnuchess 30
+.B gnuchess4 30
will generate one move every 30 seconds, while
-.B gnuchess 5:00
+.B gnuchess4 5:00
will generate one move every 5 minutes.
If two or more arguments are given, they will be used to set tournament
time controls with the first argument of each pair being the number of moves and the second
being the total clock time in minutes[:seconds]. Thus, entering
-.B gnuchess 60 5
+.B gnuchess4 60 5
will set
the clocks for 5 minutes (300 seconds) for the first 60 moves,
and
-.B gnuchess 30 3:30
