Matt?
a) orthodox
b) Loch Ness Chess
a) Yes
b) Perhaps not, on the grounds that after Black's KxQ White's recapture KxK will allow his own king to be eaten by the monster and this is surely only a draw? But White needn't recapture, he can withdraw his king by say Kg5 and let the monster do his work for him. So again the answer is yes.

Loch Ness Chess: Die lange schwarze Diagonale a1-h8 repräsentiert jenes dunkle und mysteriöse Loch Ness, und wenn ein Stein, der auf dieser Diagonalen steht, nicht mehr beobachtet ist, taucht das Ungeheuer auf und verschlingt den Stein mit Haut und Haaren. Also: Verliert ein Stein, der auf der Diagonalen a1-h8 steht, alle Beobachtungen, verschwindet er vom Brett.

A.Buchanan: @Alfred: good enough for me (2021-05-02)
A.Buchanan: JDB confirms personally: "Yes, though I had long forgotten it. The good Loch Ness Monster probllem is the last one on the same page of Variant Chess 56 (accessible on www.jsbeasley.co.uk or on George Jelliss's excellent site www.mayhematics.com, look for page 36). You may also be interested in item 6.10 in my little vanity-book 51 Flights of Chess Fancy, also accessible on www.jsbeasley.co.uk." (2021-05-02)

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)
