The Bolero idea isn’t entirely new: a Querquisite moves and captures like the piece on whose column it stands (so a QQ on e-column moves/captures like a king, a QQ on a-column moves/captures like a rook, etc).

Dear Joost,
I think the difference between Querquisite and Bolero is big enough and clear because of: a) Bolero is a fairy condition but not a piece; b) In Bolero, only the moves without captures depend on the vertical location. a). There is an even greater difference between Querquisite and Bolero inverse, of course, either in the two Bolero kinds in which we have RI.
Here is an example showing the huge difference between the piece Querquisite and Bolero: P.A.Petkov (original): White: Kh5, Sh4, Bb2, Pd3, Pd6, Locust a6 (6); Black: Kf4, Pb4,Pe3,Pf3,Pg3,Ph3 (6)
#2v Bolero (6+6) (C+ WinChloe 3,45)
Locust a6
Solution: 1.d7? (zz) – 1…g2 2.LOd6#, 1…f2 2.LOf6#, 1…e2 2.LOh6# (1…b3 2.LOa4#) but 1…h2!; 1.LOa5! (zz) – 1…g2 2.LOe5#, 1…f2 2.LOf5#, 1…e2 2.LOg5#. (1…h2 2.Sh3#!, 1…b3.LOa4#). You could never realize such content, for example, using a white Querquisite on a6 square!
It is quite normal that there is some similarity in the rules between the various fairy conditions or pieces. For example, it is well known that all kinds of conditions of the big “Circe – family” at the first sight are somewhat similar because in them there is shifting of the captured piece on some other square on the board. But we do not say that Circe Parrain isn`t entirely new because exists the classical Circe! And so on, and so on…

In 1411 wK is necessary. Without him, we have 1.Sg5 Qd4 2.Sh7 Qh8#
