Re: AlphaZero No Castling Chess

I have an even simpler modification, but with a scoring modification in addition. Only Black is not allowed to castle and the Draws are adjudicated as Black wins. You have an even simpler modification? That is my NBC-Armageddon openings idea . Not yours. I released it in August 2019, with 4 opening...

Re: AlphaZero No Castling Chess

Wait a minute, no draws? I thought this version eliminated draws by stalemate, bare king, and rep, but not fifty move rule. Surely there should be some fifty move rule draws in forty games? Unless the engine was just forfeiting players for repeating, rather than forcing them to play moves that did ...

Re: AlphaZero No Castling Chess

Thanks for opening suites too! These are from normal human and computer games? I guess the openings will be somewhat different if one side doesn't castle, maybe I will build with Lc0 and Komodo some short opening suites which are played for this variant. ? IM_4moves and SuperGM_4moves are filtered ...

Re: AlphaZero No Castling Chess

Thanks, 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. I mean, the eval has to be changed due to such adjudication rule...

Re: AlphaZero No Castling Chess

The PGN end looks like that: 48. Rc3+ {-4.56/19 1.3} Kf2 {+5.97/19 0.6} {XBoard adjudication: repetition draw} 1/2-1/2 @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/Adjuca...

Re: AlphaZero No Castling Chess

But I think there are much better ways to tiebreak that are more in the spirit of chess. Ideally making repetition illegal, stalemate a win for the stalemating side, and bare king a loss, with Black winning fifty move rule draws, could work, but I think it would still favor Black too much. The firs...

Re: AlphaZero No Castling Chess

Hold on, back when the queen was made powerful in chess, wasn't that a radical change that made the game completely different? Yet it was adopted, so why do people want to keep the nature of chess unchanged? Why are people hesitant to add rules that destroy the nature of chess, if that was done in ...
