| Sep 18, 2023 at 17:58 | comment | added | Hauke Reddmann | @loopywalt: Ah, your first example in the partial answer is exactly that what I couldn't construct and thus was unsure if it was possible at all (and thus called the problem fiendish). The belief state was flipping all the time, instinct said yes, logic said no, I should trust my instinct more :-) | |

| Sep 18, 2023 at 8:45 | comment | added | Hauke Reddmann | I wasn't aware of 121794. It becomes a duplicate "in spirit" as soon as you prove that if you move a pawn, K and R always can castle artificially by the K crawling out. (And @loopywalt - rook on a1 going to d1 jumps over b1 occupied by wB. Verbotttten!) | |

| Sep 18, 2023 at 7:07 | comment | added | Benjamin Wang | Ah, but one of the chess960 castling rules state that "all the squares between the king's initial and final squares (including the final square), and all the squares between the castling rook's initial and final squares (including the final square), must be vacant except for the king and castling rook". Perhaps a different idea might work? | |
