One player types in komi #. A message is sent to both players informing them of the value that player wanted. The second player types in komi #, where # is the same value. The server then changes the value of the komi, for the game.
# is an integral value for the komi. # is allowed to be negative. 0.5 is automatically added to the komi, after both players agree on a value.
After a handicap move, the komi is set to 0.5. Otherwise the default is 5.5.
