No.322 by Pierre Tritten – Non-standard use of Poseidon with an exotic fairy condition! (JV)


Poseidon (PO): The Marine King is named “Poseidon”. The Poseidon moves like a King when not capturing, and captures adjacent pieces like a Locust.

Locust (L): moves on Q-lines but only by capturing an enemy unit, arriving on the square immediately beyond that unit, which must be vacant.

Anti-circe couscous: When a piece captures (including King), it must come back to the captured unit rebirth square – if this square is occupied, the capture is forbidden. A Pawn capturing on its promotion rank promotes before it is reborn.

    Nice idea.

    hm…. I thought when a black square bishop (or a rook on black square) is captured, the reappearance square should be black. 🙁

      Good remark!
      Poseidon captures on a white square a piece set on a black square. Difficult to say what’s the best color square for a rebirth…

      • As far as I remember, once upon a time Popeye and WinChloe have treated rebirth squares for locust-like-capturing pieces differently. One of them based on the arrival square of capture, the other based on the square where the captured piece stood. One of them (I think WinChloe) then added option to test the other type.

    In my opinion in such a mechanism the rebirth squares looks more natural if they are in colour of the capturing square, but I still not tested how it is programmed.
    By the way – Julia, I am wonder why you are included the definition of Locust above the problem, because here is not such a piece…

    • JuliaJulia says:

      I mention Locust’s definition as I use Locust piece in the definition of Marine pieces. Of course, I could re-write their definitions, explaining how the captures works for them without mentioning Locust. But I believed that for most visitors of the site it is easier to understand Marine pieces when they’re explained as a mix of some orthodox piece (known for all!) + Locust (explained in the articles by P.A.Petkov and shown in original problems here many times).

      Another thing about this problem: can anyone solve it with Popeye? Seems like this condition doesn’t work there.. or?

    I cannot find this condition in the list of conditions supported by Popeye.
