.... Is it a Convention for Mate Puzzles of this kind to Start with Check? Sorry if this a naïve question, I’m a beginner and not so familiar with puzzles yet. With every move being a check, it is probably generally easier to solve the puzzle because of the limited numbers of possible checks from most positions, but it seems a little unrealistic.
No, not all mate puzzles will start with checks.
I’ve been playing Zen Chess lately. Anyway, my question doesn’t relate to the game itself, but to conventions for puzzles of the check-in-X-move(/s) type. Obviously, if X=1, then the first move must be check with checkmate. But in all the puzzles in the game I’ve solved thus far where X=2, 3 or 4, all the moves leading up to the mate are also checks. I guess there will more real situations where one will have mate in X (where X>1) without every move being a check (?) (below is a puzzle I made, where black will have mate in 2 moves (regardless of who's turn it is), but cannot deliver check in the 1st move), so I wondered why there were no puzzles of this type.
