Ein sehr circetypischer (hinsichtlich der Spiegelung) Mechanismus mit UW/Blockwechsel. Eine prima Aufgabe (EB)!
MR: Die Dualvermeidung beim Block e(d)3 sowie der sUmwandlungs- und der wFunktionswechsel sind brilliant miteinander verwoben. Leider bleibt der Mattzug von der ganzen Spiegelfechterei unbeeindruckt.

In the foreplan White decoys an uncaptured black Rook on to the square of origin of wSb1. Consequently in the forward play there is no longer a double check but only a single check by wK that Black has to parry with De1# (2022-05-19)
