Mar 11, 2019 at 2:15 comment added Gareth McCaughan Incidentally, although that extra knight seems to have been a mistake, there's something later in the story that fits very well with it. The king's son is a knight, and at the end the king sends his son "along with two other knights" to arrest the traitor. But maybe they're a different kind of knight since by the third diagram only one black knight remains on the board.

Mar 11, 2019 at 2:13 comment added Gareth McCaughan If the extra knight is an anomaly, here are some more just in case they're mistakes. (1) Second diagram has four white knights and a white bishop that can't have come from its home square, implying at least three pawn promotions, but only two white pawns missing. (2) Second diagram has a white pawn on c2 that wasn't there in the first diagram.
Mar 11, 2019 at 2:10 comment added Brandon_J Kinda....kinda hard to mesh these things together IMO. Any possibility of removing that third knight with a story edit, or at least explaining that he is an anomaly? Obviously one is harder than the other, so I won't push it.
Mar 11, 2019 at 1:57 comment added Brandon_J @GarethMcCaughan here is how to do the built-in thing. I think it works for FEN and PGN.
Mar 11, 2019 at 1:54 comment added Gareth McCaughan ... that could just as well (in-story) be a deliberate trick to confuse white, rather than indicating any malfeasance within the black camp. Etc.
Mar 11, 2019 at 1:54 comment added Gareth McCaughan E.g., the sort of thing I want to be able to say is "look, in this position you can tell that black's last move was X, but that means that such-and-such a piece could have done Y to protect the black king but didn't, so that piece is the traitor". But if we don't know by what rules the game is actually being played, that sort of reasoning can't work. We could try to make the rule-violations themselves be the evidence of treachery, but if e.g. we decide that one of the black knights in the first diagram is a bishop in disguise then [...continues]
Mar 11, 2019 at 1:49 comment added Gareth McCaughan This sort of puzzle seems hard to make any progress on, because plainly we aren't dealing with an actually-possible chess game, played by the normal rules, which somehow tallies with the events in the story (because there are impossible things in the diagrams); but if the chess game isn't being played by the normal rules then it seems like anything could be happening and it's hard to see how to draw any actual conclusions.
Mar 11, 2019 at 1:48 comment added Gareth McCaughan Also not making any sense at first glance: in the first position W has "obviously" made at least one pawn capture (maybe two for pawn-promotion reasons) but black still has 16 pieces.
Mar 11, 2019 at 1:44 comment added Gareth McCaughan So, is it deliberate that the first diagram has three black knights even though all eight black pawns are still on the board? I mean, obviously it might be -- it's unclear what sort of metaphorical shenanigans might be going on -- but it seems rather odd.
Mar 11, 2019 at 1:43 comment added Gareth McCaughan Damn, is there a built-in SE FEN viewer? I didn't know, so I just copied-and-pasted the images from the site the OP linked to. I bet the SE ones are nicer-looking. Oh well, never mind.

add diagrams
Mar 11, 2019 at 1:39 comment added Brandon_J Maybe try showing the chess positions using images or the built-in stackexchange FEN viewer. I think maybe people don't feel like clicking the links.
