Henrik Juel: Here the extra joke is that the (dummy) pawn can move (2020-04-14)
James Malcom: The newly born black pawn is not a dummy pawn, in my opinion. Unlike the dummy, it still has the right to move foward in principal. Since it is new and has never moved, it sill has the right to make a double-step if allowed, as in Horde Chess (https://lichess.org/variant/horde). (2020-04-14)
Henrik Juel: I see your point, James (2020-04-15)
James Malcom: Seems that Gerd might have missed including pawns promoting to opposite color pawns the new update. I'll email him tomorrow morning. With accordance to the rules, they have 4 first moves as a 7th rank pawn does. (2020-05-03)
Gerd Wilts: Promotions to pawns are now also supported. (2020-05-03)
James Malcom: Many thanks Gerd! (2020-05-03)
A.Buchanan: I had missed these 6 miniatures: they are terrific! Can I ask to replace Sg8 in this one with L so that it's not giving check in the starting position. I guess it's kind of crass though economical to replace with pawn! (2020-10-13)
A.Buchanan: Dummy pawns can in principle move imho: it's just that they're usually blocked by the edge of the board. If one was teleported somewhere else on the board by some mechanism, then they would just start moving. So completely different kind of animal from a dummy, which genuinely cannot move :D (2020-10-13)

Supersession of P1380851

Superseded by P1380851

The 2018 FIDE laws state: "3.7.2 on its first move the pawn may move as in 3.7.1 or alternatively it may advance two squares along the same file, provided that both squares are unoccupied."

Hence Black's newborn 8th rank pawn, which has never been moved before, reserves the right to commence a double-step on its first move, and likewise White receives the right to capture it en passant as they do with a 7th rank pawn.
Henrik Juel: This un-dummy-pawn is like a pawn created on c8 by the Einstein condition
The retroplay looks wrong, what about 1... d8-d6!? 2.d7-d8=sB!? c6xYb5 (2020-04-30)
James Malcom: That makes much more sense Henrik. I have edited it accordingly. (2020-04-30)
A.Buchanan: You don't like Adrian's (: haha? What about :) then? In heraldic terms, it would be described as "regardant". See 270 on https://www.heraldica.org/cgi-bin/atlas.pl?12. I don't know the word for "non-regardant", which is the default direction for the head, e.g. most of the others on that page.
We could replace wBa6a7 with wSa6, but alas having the 3rd knight is non-thematic & distracting. The other thing I would've liked to do is empty b2 so the promotion is forced to be to D. Such a tiny problem should have precision promotion. Needs more thinking. (2020-05-01)
James Malcom: UPDATE: The position has been edited to have one less piece and a precise queen promotion. (2020-10-12)
A.Buchanan: There is dialogue here which is now orphaned by a change of diagram with new matrix. Suggest we revert to the older diagram and mark it superseded by a new PDB entry here (2020-10-12)
James Malcom: I agree-it is now done. (2020-10-12)

A.Buchanan: Curious that retro a7-a8=sT discomforts the animation still - maybe you should report to Gerd? (I trouble him with enough stuff already - don't want to be the only one emailing him! :-) (2020-05-11)

James Malcom: This problem was only half-finished before I fell asleep. It’s fixed now. (2020-05-11)
A.Buchanan: Great! You could save another piece I think -sLg6, -sBf7, + sDf7. This also removes the obtrusive promotion (2020-05-11)
James Malcom: Yes, that is true. Position edited. (2020-05-11)
James Malcom: I see nothing wrong with fiddling if it improves economy. (2020-05-11)
A.Buchanan: If promotion to Bl unit is allowed, can’t Bl just have played e8xd7+ or g8xh7+? Can replace bPd7 with bR but eliminating bPh7 is more complicated. Need +wPh7 +bPg6h6. And also bRb7 to prevent discovered check by bPc8 prior to e7-e8=bK. I think that’s watertight now! :-) (2020-10-13)
A.Buchanan: The issue is that there are two or three levels of Bl promotion joke: this problem relies on the "basic" joke where black officers can be created. But where's the line to stop us promoting to Bl pawn or king? If we go that far, then a position like this 2kr3K/1r1r1qrR/7p/8/8/8/8/8 is required. Oh dear: sorry to have brought it up :( (2020-10-13)

play all play one stop play next play all
https://chess.stackexchange.com/a/29992/15543
A.Buchanan: Hi James, couple of nits about old Bosma:
(1) From the 1985 Laws: "Article 5. THE MOVES OF THE PIECES The King (a) Except when cast[l]ing, the king moves to any adjoining square that is not attacked by an opponent's piece." This is separate from Article 9. CHECK 9.1 "The king is In check when the square it occupies is attacked by one or two of the opponent's pieces; in this case the latter is or are said to be "checking the king.' 9.2 Check must be parried by the [move] immediately following." This point may have been an assumption in earlier compositions, as e.g. it prevents kings from being adjacent.
(2) And again from Article 5. "(f) Castling is prevented for the time being - (i) if the king's original square or the square which the king must cross over or that which it is to occupy is attacked by an opponent's piece," Does this prevent your 1.0-0?
What do you think? (2020-11-08)
James Malcom: Ah, why did I but never bother to look at the castling rules!

Well I see nothing against adjacent kings, and seeing about how the "loophole" was about was not explicitly stated couldn't be done, I see it as allowed, and thus what to watch out for in cooks.

The rule on castling says "piece," not pieces. So, quite simply, castling in, out (P1381498), and through (P1381499) check is allowed in my view. (2020-11-09)
James Malcom: Furthermore, if a king is "attacked," they are in check, plain and simple. So, since a triple check/ attack is not defined as a danger to the king, the king may go to any such square, including the acts of catling and adjacent kings.

Also, going by the law itself, and not the Bosma conditions, the king may be captured, but it does nothing and that side can never be checkmated, while Bosma Chess itself allows no king capture. But since the effect is the same, allowing for my jokes to be C+ by Winchloe if the program agrees. Maybe try out my castlings in it? (2020-11-09)
James Malcom: And indeed Andrew has tested my castling problems now-all are C+? (2020-11-14)
James Malcom: Typo-!, not ?. (2020-11-14)

A rather... complicated "joke."
A.Buchanan: If one allows promotion to sB (and there seems no reason to disallow it since promotion to pawn, king and foreign units are allowed) then the problem is cooked. There is no universally agreed notion of how a pawn can move if it starts on the first rank. Does it get a double hop, and if so on which rank? But the problem is unsound in any case. (2022-02-10)
James Malcom: That is if, yes. But I don't think this problem ought to be left as is: a demonstration of the levels of absurdity and tomfoolery old rules used to allow. Promotion to a piece of another color and dummies were loopholes, yes, but promotion to a black pawn was never included, not even implicitly. All pawns are pieces, but not all pieces are pawns.
