|Staugaard castling:||This is a fairy kind of castling, originating in a loophole in the Laws of Chess spotted by the Danish composer Conrad Staugaard in 1907. A promoted rook can be regarded as never having moved. This allows for vertical castling with wKe1 & wRe8 to wKe3 & wRe2 (or analogously for Black). (from Die Schwalbe)|
Some more words about the invention by Andrew Buchanan (a copy from No.1615):
Conrad Staugaard (see the biography) invented the condition later termed Pam-Krabbe. He seems to have been a funny and kind figure: like a Danish Lewis Carroll, but a socially-aware entrepreneur. He deserves to be commemorated with his condition, which is how WinChloe and PDB already identify it. Recently discussed on PDB.

Solution: (click to show/hide)
White castling in a solution, black castling in the other one.
Some justification for the solutions :
Orthodox counting, 13 white moves are apparent (white Rook h1 was
captured on f6 and replaced by a Phenix Rook e2 promoted on e8).
Disappearance of Pawns d2, d7 has to be explained.
With white castling, white extra move can be used to capture bPd7.
Without white castling, bPd7 must promote to disappear.
Probably the definitive presentation of this castling idea!
There is an error in the animation: The 10th move of the first solution plays the Bd7 to b4, instead of Bf8-b4.
The animation is outstanding!
I did not find a way to go next move with the keyboard.
Also at move 6 of the first solution the black king becomes a rook (it does not disturb to see what happens!)
a very nice problem!
The both corrections to the animation are done! Thank you, Kostas, Jacques! (for the animation I’ve made long English notation to replace the short French one, but missed one French R for K 🙂 )
Julia, an easy trick for translating a solution : paste the text in winchloe in the area of a diagram’s solution then in the item “solution” you have “translation” you choose the two languages (exemple from french to english) …and it is done!
Jacques, this doesn’t change the french characters (ç and é) for the c and e files, due to which the animation doesn’t work. You then have to do a “find and replace” twice, which is available in the same translation menu.
You are right, it is just slightly longer, anyhow, I am going to ask this from Christian! (who knows, perhaps he’ll accept to change that?)
and after all, for the animation I need to have departure squares! Replacing ç and é would be much easier than adding all departure squares for long solutions. Maybe something to ask from Christian as well? 🙂
So… perhaps there is nothing to ask from Christian!
you go to “options for solving” there you inactivate “short notation” and also inactivate “e->é ; c->ç”
and now to options
All that of course only if WinChloe knows the fairy rules of the problem!
Thanks for pointing this out, Jacques!
I remember having used these options earlier, to convert the lengthy solutions of some of my problems to Py2Web friendly text. They are under “Solving options” and now I was looking for them under “Preferences”.
