play all play one stop play next play all
A.Buchanan: Why not sBh3 on h2, removing sTh2? (2020-10-21)
Arnold Beine: Then there is a solution in b) without joke: 1.Kf1 Ga8 2.bxa8=L#. (2020-10-21)
A.Buchanan: Thanks Arnold - I had a blind spot there, but knew there had to be a reason. In a), 1. a8=sG! also wins but not so quickly. More interestingly, I think b) 1. Kf1 Ga8 2. b8=Q! Gc8 3. Qxc8! wins the pawn or 2. ... Rg7 3. Gxa8+! R~ 4. Qb7++! Maybe someone can check this indeed win for White. (2020-10-22)
Arnold Beine: There is no need for checking 2.b8=Q!??, because Q-promotions are not allowed in Grashopper Chess. (2020-10-23)
A.Buchanan: Thanks so now we’ve found an explanation of why it is defined to be grasshopper chess! A lot of time and effort can be saved in chess composition if the default format is “no-cook chess” - a fairy format in which all unintended solutions and defences are by definition illegal! :) (2020-10-24)
