|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:
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.

Fake castling :
From the diagram, it looks as if white has just castled.
In fact, it is a fake castling and black has previously castled!
Some justification for the solution :
Orthodox counting, a minimum of 12 black moves are apparent :
Ke8-h4=4 +Qd8-a3 (for b2×a3)=2 +c1=Q-c2=6.
But h~-h4+ K×h4 implies too many white moves (for wRh1 to reach e2, not through h3).
Same, d7×c2-c1=Q implies too many white moves (white has to capture missing bLc8 and bPe7).
So, instead of a minimal number of 12 black moves, an effective
number of 14 othodox black moves is reached, 1 too many...
