Re: [computer-go] Protocol B

Hi David,

But can't an offending program simply do it's offending before the agreement 
phase?   All it requires is to refuse to pass.    

I don't accept the notion that the protocol encourages ugly behavior, it's a 
separate issue in my opinion.

Don't forget that to offend after the protocol has been triggered, requires a 
program to make the initial pass move which triggers the protocol, which by 
itself indicates that a program is willing to stop the game.   There is no 
reason for a program to trigger the protocol just so that it can start 
behaving badly when it could just as easily do this anyway.
