    The stipulation is h=2 2.2.1.1
    The set play is not interesting as it only repeats the actual, so I didn’t mention it.
    With 2.2.1.1, the full solution is:
    1.KRc2 Kd5 2.KRc6 Kxc6=
    1… Kd3 2.KRc2 Kxc2=
    1. KRc6 Kd5 2.KRc6 Kxc6=
    1… Kd3 2.KRc2 Kxc2=

    KR is a cunning fellow. But in my opinion (which I can not verify through WinChloe) the problem is cooked, such as.: 1. … Kf3 2.KRg2 Kxg2 or = 1 … Kf5 2.KRg6 Kxg6 =

  3. JuliaJulia says:

    Have got a new version of Py2Web from Dmitri Turevski, allowing to show the move to the own square. Now 1.KRc6-c6 works in animation! Thanks a lot to Dmitri!

  4. Georgy EvseevGeorgy Evseev says:

    On main page the piece is mentioned as Kangaroo-Lion, not as Kangaroo-Rose, so the description looks puzzling.

  5. Kjell Widlert says:

    Using the same hurdle twice in the same move – very amusing idea! I am still smiling.

    • Georgy EvseevGeorgy Evseev says:

      BTW, is Rose-hopper not enough?
      I have not tried to computer-test it, but it looks like this kind of hopper still can only oscillate between c2 and c6.

      Or is it also possible to use something like Kangaroo2016-Rose (the piece which has to jump over 2016 pieces before stopping)?

      • shankar ram says:

        Georgy,
        Rose-hopper allows cooks/duals!
        And yes, a Rose-Kangaroooo.. would also work! (jumps over oooo.. pieces ;-))

        • Laco Packa says:

          You’re kidding, but something rational in it can be found. For example, Kangaroo3-Lion and a circle with two hurdles. In the position wKLe8 – bPc7, c3 may move Lion only to b5, then in the second move to any empty square of its circle (except b5).

  6. Nikola Predrag says:

    -…”Rose-hopper allows cooks/duals!”…-

    Popeye doesn’t allow null-moves so I can’t test it, but what about:
    bRose-hopper (c6) and wFers (e4) or with wKe4 but wPb4/bPb5?

  7. shankar ram says:

    Nikola,
    – Rose Hopper c6, Fers e4 is sound!
    – Rose Hopper c6, WKe4, WPb4, BPb5 still has duals/cooks. Position of Ps makes no difference

  8. Nikola Predrag says:

    Thanks!
    Well, yes, bPb5 removes the cooks when Rose-hopper plays from c2 to f5 (using wKe3/d4 as a hurdle). But it may move from c6 to f3 over wKd4/e5 and then loose a hurdle.
    So, wPb3,bPb4,bPb5 should at least remove the cooks with Rose-hopper playing to f5/f3.

    In principle, the nature of Rose-Kangarooooo (which needs 2 or more hurdles) is used only for cook-stopping on a “small board” 8×8. Adding one file left to a-file would allow KRc2 to play to f5 over wKe3 twice (or more times).

    The intended solutions require no more than a Rose-hopper.

    Laco’s Kangaroo3-Lion offers interesting possibilities.
