I composed this problem almost together with the next one, they were intended for my long article about Patrol chess in Pat a Mat, but lack of space made it impossible to include them both. Plenty of dual avoidance, promotion forces choice of white play as black can be able to defend double check by capture of common patrolling piece.

Personal rating: B.

Juraj Lörinc, 325 Pat a Mat 24 - April 1999, 3rd HM Pat a Mat 1998-1999, Notes: 940 Sent: 238, fairy h#2 can be found here.

Third example of my idea of double-check mate with active pin, first two examples were F1603 The Problemist March 1996 and 1st Prize JT Brown 50 C 19.11.1996 - B. Well, I recently discovered that my other original idea of reciprocal batteries isn't so original as I expected. Now I also tend to doubt that this doublecheck mate with active pin isn't original too... but who can say it precisely without an evidence? :-)

Echo diagonal-orthogonal. Somehow I only corrected the position of Romanian duo. I think it was done in e-mail communication with Vlaicu Crisan and in fact I didn't know they are going to give my name over the diagram...

Don't let yourself fool by the description of the moves. There is no Lacny cycle here as the mates are played by different equihoppers. A change scheme isn't new, but strange property of Symmetry Circe allowed change of set of squares available for white equihoppers.

"An ultra-super-Zagorujko!" said the judge Bas de Haas. Well, I admit I was inspired by older problem by Reto Aschwanden, but I used Circe Parrain for moving directly checking piece (not hurdle) and to the only square (not two). On the other hand, I allowed more keymoves, thus getting really very rich changed play.

Personal rating: A.
