In a game of "Sort of Almost Chess", the variant from Mr. Betza that replaces one of the queens with a Marshall (the Rook+Knight compound, also known as the Chancellor, or the Empress in Fairy Chess circles), this surfaced as a possible endgame that was narrowly avoided by a slightly controversial promotion by Black. The Marshall and Queen are represented in the diagram as Knight and Bishop, respectively (given that they can both move as rooks).
[Date "2018.06.26"] [Round "-"] [White "NN"] [Black "James"] [Result "?"] [FEN "7B/8/6K1/8/8/1k6/6P1/n7 w - - 0 1"]
Given that Black's to move, I'm wondering if it's possible for either side to get a win from this position. A Black Queen (the promotion that actually took place instead of this position) is a forced win for Black with careful play, and Marshall vs. Marshall is almost certainly a draw, but the similar yet different power of the pieces here makes it a complex problem.
