I mean, the eval has to be changed due to such adjudication rules, otherwise it will play dumb, unrepresentative games. I don't have time to look at the code, games and PGNs, just left it play 40 games at 2:1 time odds, to see the sensitivity of the game to strength.Laskos wrote: ↑Fri Dec 06, 2019 2:34 pmThanks, seems to work now. Will check for some properties, interesting. Does the engine know something how to play it, or it plays as usual, only discovering that it lost/won at the last move? I have no time looking at PGNs and games.MTaktikos wrote: ↑Fri Dec 06, 2019 1:10 pm@Laskos
Looks like the incorrect adjucation comes not from the engine SFLarry, but is an Xboard adjucation by the GUI
Please try the following:
1) In Winboard's menu Options/Adjucations uncheck the points, where Winboard adjucates itself insufficient material, trivial draws,
and verifies engine claims
2) In Winboard Options/General uncheck the "test legality" by Winboard
3) Chose New variant/larry
4) In Edit/Paste position from clipboard copy-paste the position
4b1NK/3pPp1N/3P1PpP/6Pk/6p1/6p1/6P1/8 w - - 0 1
(in this position, Black ist the side that has by Zugzwang to make the first repetition
5.) Chose Mode/Analysis mode. SFLarry should (correctly) anounce a mate
