    White to mate in 3 moves.


    Bear in mind, black can check your king in certain variations which forces you to lose a move. That's all the help i will give you!

    Surely Kb4 is the 1st move!

    I followed that path for a while. If you're looking for me to give you a hint though, think again! The combination is counter intuitive, give me a variation and i'll try and tell you the refutation. There are in fact two ways to solve this, as black has a couple of defenses to the opening move.

    After Rd1 the best white has is mate in 4, which is incorrect as the puzzle wants mate in 3.

    How about 1 Na7 threatens 2 Rh6++ so blacks defenses are Rh8 and Rd2.

    If 1...Rh8 then Kb4 and Ra1++ is unstoppable.
    If 1...Rd2 then Kb4 and black has to choose which mate to defend against between Ra1++ and Rh6++. Either way, he can't defend both.

    OK, now tell me what I missed, because I'm sure I missed something.

    FWIW, there is also Rd6.

    Question about this type of puzzle--If mate in 3 is required, then is mate in 2 acceptable?

    For instance, if:

    1.g6 Ra8
    2.Rh5#

    Does black "win" because he forced the checkmate to occur in 2 moves rather than the required 3 moves?

    No, the mate has to be in 3.

    When the stipulation is mate in 3 it means that there is no mate in 2 against best defence.

    You are right. I feel normal again. The best I can do then is mate in 4, but a monkey can find a mate in 4 in this position.

    If mate in two is okay.... ..how about

    1. Nf5 Rd7 otherwise 2.Rh7#, or if Rh8 then Re7, etc.
    2. Re5 threatening mate on either the first rank or h file?

    1. Nf5 Rd7 2. Re5 Re7! and there needs to be at least 2 more moves to mate.

    leisurelysloth indeed!

    1. Nf5 Rd7 2. Rd5! and now black must choose. Built on leisurelysloth's idea.

    EDIT- Dang, still doesn't work because of 2. Rd6!!

    that was easy.
