question abt fairy chess pieces

Pretty sure theres some positions that it's impossible from with an optimal opponent, even on an empty bar with just you king+archbishop and their king, but ik there are plenty that it's possible from.

I don’t think Checkmate is possible with a Knight, a King and a camel, even if that’s possible then it’s too tricky and unpractical
It’s possible
(The white knight on e7 is a camel)
Is that forcible?
Actually, no (because knights and camels can only make even cycles)

What are “even cycles”?

Dave McCooey solved most of these checkmate problems about 30 years ago.
See here: https://www.chessvariants.com/misc.dir/endgames.html
For example, you can force checkmate with KNW (W = Wazir, moves like a rook, but just one square) but 80% of the positions of KNF (F = Ferz, moves like a bishop, but just one square) are draws
Also, there are analysis of K+piece vs K+piece, for example a King and Amazon (Queen+Knight) wins K+Q in about 50% of the position, but lose in about 20% of them (!!!)
is it possible to force mate with only a king and archbishop (bishop+knight)? just wondering
