[gahtan-syarif]

make fc consistent with fide and uscf rules as well as with cutechess

fix #410

[gahtan-syarif]

+ grep 'Finished game'
+ sort -n -k 3
+ diff ./cutechess-cli-out.finished ./fastchess-out.finished
35c35
< Finished game 35 (sf_1 vs sf_2): 1/2-1/2 {Draw by adjudication}
---
> Finished game 35 (sf_1 vs sf_2): 1/2-1/2 {Draw by insufficient mating material}

how do i access the pgn for this?

edit: nvm found it

[gahtan-syarif]

done 👍

Btw finding all the situations in which only one side has no legal set of moves for checkmate is quite complex, so i decided to take the cutechess route of doing it by adjudicating as draws when the opponent only has a lone king: cutechess/cutechess#717

mh does cutechess have the same termination strings? i find this weird tbh, maybe it should be behind a "strict fide" feature but i don't care too much about that as of now because it's not the main focus

[gahtan-syarif]

Yeah cutechess has the same termination strings

mh.. i don't really like this, fc is primarily to test engines, we don't need 100% fide compliance, if we did then the first illegal move should be ignored and the engine asked to make another move and only lose on the second move. Making the engine lose in 100% of the cases is more consistent imo
