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

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 ...

Re: AlphaZero No Castling Chess

I see the stalemate endings/insufficient material vs bare king/perpetual check draws as a fallback or safety net for the daring player who sacs material while trying to win (the old "playing with a draw in hand" strategy), not as a way to force 'weaseling-out' draws, which to me would seem to be a ...

Re: AlphaZero No Castling Chess

I think Chess should have sharper games overall with a lower draw rate. I just thought about this variant the other day: If the game ends in draw, the first player that checked the other during the game is awarded a win. There we go, no more draws and no more hitting our heads against the wall figu...

Of course, he didn't play poorly. He got 2nd place.
Of course nothing wrong with 2nd place, even for Carlsen. But he lost to So by 5 to 1 (using normal scoring), which is why it looks so bad for him. (I didn't intend the pun, but noticed it after writing it!).
