Solution text from the 2/1899 issue: "A clever rendering of this "triple idea." It will be seen that Black cannot play simply 2.R-Q sq on account of 3. Q x Q ch."

James Malcom: I found this most excellent early Valladao while ago, but only today did I finally find it again. This is the second one that I've found, i.e. P1380523

Is this the second oldest known Valladao after the 1867 P1360420 found by Keym?

The mainline should be C+, with the "legitimate" ep key, but with many dualed sidelines. (2020-10-14)

Henrik Juel: Adding wSe7 would help (2020-10-14)
James Malcom: Henrik, Mario-many thanks!-has now fixed the position. I had missed the wSe7 when entering! (2020-10-14)

'ASD': "Diese Aufgabe war eine der ersten, die der jugendliche Komponist veröffentlichte. Wenn sie auch noch nicht ganz so ausgefeilt ist, wie man es heute bei modernen Zweizügern findet, so ist das Stück doch immerhin für den Anfang als sehr gut zu bezeichnen."
