MD: 'Zweimal Anti-Lewman mit Mustermatts.
Leider gibt es in Lösung a) Duale:
… 2. exd5 Ld3#
1. ... Lg4 2. exd5 Le2#
und zwei Nebenlösungen:
1. Tg4 Lxg4 2. Lb3 Le2#
1. exd5 Lg4 2. Lb3 Le2#
Leider haben wir das zu spät bemerkt; auch die verfügbare Technik war damals noch nicht so weit, schade.'.
SCHRECKE: Die Zwillingsbildung für b) lautet: sK nach d5
Mattzug in b) ist 2. ... Le4# (2021-08-23)
Henrik Juel: ... and part b is C+ Popeye 4.61 (2021-08-23)
