The "worsen" is interesting. Did you come up with it yourself?

If you're talking about the piece name.

I actually was thinking about the move.

It's Jörg Knappen's.

Nice! Also logical. It's not in this game, of course (unless I'm missing something); do you have a link to where it is?


HaruN Y wrote on Sun, Feb 11, 2024 05:31 PM UTC in reply to Bob Greenwade from 05:16 PM:

It's not in this game but is mentioned on this page. I included it as a piece that can only be obtained through promotions in my interactive diagram because it just felt right. Also pressing restart will shuffle the pieces since I'm not a fan of the starting position on this page.

Ah, I see it now -- the last paragraph under Notes.

Thanks! :)

HaruN Y rediscovered the 135-degree-rose recently and named it "Worsen"

I don't like this name, I suggest "Rose of Jericho" instead.

I intentionally gave it a name that sounds like a verb here for a pun.

Can you provide a movement diagram for that?

By chosing a direction for the first turn you create a chiral piece, and a quite messy one of its kind since it mixes wide and narrow moves. The only other rotationally symmetric nightriders are the two possible "half quintessences" by chosing lateral (3L) or diagonal (3D) continuations only. I still have them in my mind to stage them in some game to be designed.

Of course, there are also potential combination pieces, the Boa used by problemists is only one of them.
