    I am curious how everyone is getting 18 moves. I am getting 17.

    Help.

    Once the BR is next to the WK I do not see how to dislodge it or to allow the WR to take it with check. Any clues? (other than it should take 17/18 moves and end with a rook check)

    There is a way to escape the checks. It requires a good imagination to see it, though.

    9.Kg2 with 10.Rh5 to follow. Playing it on move 8 makes no difference.

    It might well be true, but things aren't that easy I remember... what about 9. ... Rg8.

    Aha - that indeed does force white to expend an extra move.

    I've lost count of how many times I've posted this problem and no one has ever found this variation.

    Can White win?
    I set this up on a board and couldn't figure it out. After I came back to it an hour or so later, I had a revelation... I thought to myself: man, if only that white rook was on a3 and not a2...

    ...I'm such an idiot.

    (Yes, I set it up wrong.)

    Thanks to the new hidden text® feature, I can give the solution:

    [Do not mouse-over the blue tablet if you are still solving...]

    1. e3! Rxe3+ 2. c3! Rxc3+ 3. Ka2 Ra3+ 4. Kb1 Ra1+ 5. Kc2 Rc1+ 6. Kd3 Rc3+ 7. Ke2 Re3+ 8. Kf1 Re8!
    8...Re1+ 9.Kg2 Rg1+ 10.Kf3 Rxg3+ is one move faster for white
    9. g4!
    Not 9.Kg2? Rg8 10.g4 Rxg4+ 11.Kf3 Rf4+! with checks along the 4th rank
