    A friend gave me this position, saying there was a mate in two. Probably I'm just a doofus, but I dont see any mate in two, and am thinking it is not possible. Your thoughts?

    I'm afraid your friend is right.

    1.Rd6!! - a spectacular shot. The threat is simply 2.Re6#.
    1...d4 2.Qxc5
    1...Bxd6 2.Qg7
    1...Nxd6 2.Qxe7
    1...Kxd6 2.Qb8
    Imagine the look you'd get from an opponent if you actually got to play a move like 1.Rd6!! in a real game!

    Ah, another something you would never look for.

    I know! I would have done something like taking the knight, which seems like a good enough move for me.

    1. Rh6!! appeared to me like 1. Rh6[what in hell is he doing??????]??

    I wish I had the mind to look for things like that...

    The trick is watching out for troublesome Black King flights. If he is allowed to go to f6, White will not be able to set up a mate.

    So, the key move must stop him from going there. And that's the main point. Since zugzwang isn't possible [how on earth does 1...d4 damage Black's position?], then we need a move that

    a) stops ...Kf6
    b) threatens mate next move

    After this realization, finding 1.Rd6!! is straightforward.
