   Just wondering: how does it look like?  How can you do any dispute
   negotiation over GTP if it is designed so that engines have no direct
   control over what is happening whatsoever?

I'm glad you asked.

The KGS protocol DOES in fact allow some limited control.   

But first of all, let me mention that "final_status dead" and
"kgs-genmove_cleanup" IS a real disagreement resolution protocol.   

Your program has a measure of control for a few reasons:

 1. You can report a false number of dead stones.

 2. You have a choice of either ignoring the kgs-genmove_cleanup
    protocol or accepting it.

Point 2 may not seem important, but having a choice is at least as
good as having NO choice and gives you some control.

For instance, ignoring kgs-genmove_cleanup give the program the
ability to pass a decision to the tournament organizers.  I thinks
it's possible to make this work to the advantage of the program.  I'm
thinking in terms of seki detection or at least human assisted help in
this regard.  So it may be possible for the program to manipulate the
tournament organizers into resolving seki, when a mistake could be
fatal to the program.

But the fact that the protocol is optional should be able to be used
even more to your advantage.  I think for my program, it's better to
let the tournament organizer make the tough decisions but I'm still
thinking about this.
