    ...does White need at least to checkmate Black if

    a. White may only moves his knights?
    b. Both may only move their knights?

    Just came up with this one, so I don't know the solution either yet 🙄

    Okay a. was too easy and it's even better ifBlack has to checkmate White because then there will be no waiting move:
    1. e3 Nc6 2. g3 Ne5 3. Ne3 Nf3 mate
    White would need 4 moves to mate like that.

    Part b. is more difficult though, but should be possible also 🙂

    edit: I found mate in 9 so far.

    Well, he moved some pawns, so I'm guessing it's not a valid solution.

    The solution with the pawn moves is for part a.
    For part b. I found 9 moves.
    1. Nf3 Nf6 2. Nh4 Nh5 3. Nf5 Nc6 4. Nxe7 Nb8 5, Nf5 Nc6 6. Nxg7+ Nxg7 7. Nc3 Ne7 8. Nd5 Ngf5 9. Nf6 mate

    very nice indeed! don't think i can beat that 🙄

    can you think of similar one like this? i was thinking of "both may only move knights and bishops and the mate has to be with bishop" but it turned out to be too easy.

    Very nice. Looks like the Knight Award goes to Thud unless someone can find a solution in 5 🙂

    It's also possible to kill the Bishop and mate in 5.5 moves.

    There is no way to improve that 😉 Four moves to capture the queen and two to mate 😉
    Anyway, an interesting question is if you require both side to alternate moves with certain pieces what is the shortest mate? For instance, both sides move pawn, then knight, then bishop, then again pawn, knight, followed by bishop, and so on.

    Sounds fun. I guess in your example it's too easy though. White plays 1. e4 2. Nf3 3. Bc4 4. any pawn 5. Ng5 6. Bxf7 mate
    Black can play anything on the queenswing in the meantime 🙂

    Yeah, but you started with white playing e3. It's white that's the one who has to only move knights, right? 😕 I'm sure I'm confused.
