How do GUIs detect mate scores if there is no fixed format?
Do they look at the score and guess the mate range like this:
0.. 9000: normal
9001..10000: mate is 10000, mate in one move is 9999 and 9998, ...
10001..15000: normal
15001..16000: mate is 16000, mate in one move is 15999 and 15998, ...
16001..16384: mate is 16384, mate in one move is 16383 and 16382, ...
16385..31000: normal
31001..32000: mate is 32000, mate in one move is 31999 and 31998, ...
32001..32767: mate is 32767, mate in one move is 32766 and 32765, ...
Or even string output of the engines:
M0: is mate
M1: is mate in one move or ply
M2: is mate in one move or mate in two plies?
...
other?
And negative values mirrored. (-M1?)
What if the GUI sees a score of 16380 and later a score of 20000
and then 32760?
Are there definitions in the Winboard protocol or in the UCI
protocoll? Are there differences?
