Henrik Juel: The problem was reprinted in Die Schwalbe to commemorate the author's death a century earlier; here the dual after 4... Tb5 was not mentioned (but the immaterial promotion mate dual was...) (2017-02-14)
Dieter Berlin: Die sog. Verteidigung 4. ... Tb5? wird in keiner Quelle genannt oder moniert.
