304. Three-Toed Box Turtle. As (semi-)promised, here's the mirror counterpart to the Three-Toed Sloth from a week and a half ago. It shares the same history, except for the extra step of making it as a mirror. (And a special salute to HaruNY for the name.)

To recap: This piece moves one step directly forward, or diagonally backward and to the left; or leaps two spaces diagonally forward and to the left, or backward and to the right; or leaps two spaces forward and one to the right; or makes one or two leaps of two spaces directly forward. (fWblFfD2rfNflbrA)

This isn't necessarily the end of it, either; the fun thing about completely asymmetrical moves like this, as well as the Blue Gecko and related pieces,* is that mirroring and rotating allows for up to eight members of the move family -- sixteen, if you allow for turns of 45° as well as 90°.

Aside from an unwanted rendering artifact or two, this came out somewhat better than I expected. It's the same size as the Three-Toed Sloth piece, and thus much smaller than the full-fledged Turtle, and is pretty easily distinctive.

*Besides the Blue Gecko, I've created the Purple Finch as a left-to-right mirror, and Adrian King's original Jupiter game has a near-match front-to-back in the White Fox (if I were to use it in a game, I'd make a full front-to-back mirror of the Blue Gecko).

...the regular Turtle (the move for which I still need to edit).

Dang it, now I can't remembeer what I need to edit it into (from Q4AD).

When I was kid I watched much TV and consequently thought that bell peppers are spicy, because they’re peppers. Until I tried.

Now I’m almost a vegetarian for several years, and I often eat salads with it.


Bob Greenwade wrote on Thu, May 16 06:27 PM UTC in reply to Aurelian Florea from 06:05 PM:

Well, the bell pepper kinda does, at that.

(Green ones and red ones taste pretty nice on pizza or in salads, too.)

No, it is because it looks like a heart!

This is funny!

Hopefully not for how bad it is. ;)

303. Bell Pepper. I had been going to do something else today, but then I got a pizza last night and realized that there were two vegetables on that pizza that weren't represented yet in the Pizza Kings, Food Fight, or elsewhere. What I'm giving today is the Bell Pepper.*

Like many (I think about half, just as a guess) pieces named for food, the Bell Pepper's move roughly draws an outline of the food itself. It steps one space backward, or leaps two spaces forward to sideways; or leaps (1,2) in any backward direction; or leaps (1,3) or (2,3) in any forward direction. (bWfsDbhNfhCfhZ)

I'm undecided as to whether I should put this into the Food Fight variant; maybe if someone were to point out how one of the pieces is overwhelmingly strong or uselessly weak. (The game's probably fine as it is, though.)

And of course the model is just as vague of an approximation of the actual fruit as the move diagram.

which means that my Zip is 11th both in your wall and in its home game

and I write this text while using the 11th line of our underground, which was the shortest when I started to learn the metro scheme several years ago, but now it’s the longest circle line in the world


Bob Greenwade wrote on Thu, May 16 01:38 PM UTC in reply to Lev Grigoriev from 07:10 AM:

You'll also find two listed as #12. I need to edit the entries from Pirate to Zip and subtract one from each number.


Lev Grigoriev wrote on Thu, May 16 07:10 AM UTC:

BTW, I listed the earliest comments on your page and didn’t found PotD #4


Bob Greenwade wrote on Wed, May 15 11:16 PM UTC:

Now the one for today...

302. Yadj / Bishop's Dog. This is a piece that initially made as part of the Tifinagh set, only to find that there was already a piece elsewhere with the exact same move. I couldn't come up with a better move for the Yadj (ⴵ) than three spaces diagonally, so I left it as-is. (B3)

The other version of this piece, the Bishop's Dog, is one that I found in Adrian King's Jupiter, though I understand that its actual first appearance was in another of his games, Typhoon.

Whichever model is preferred, I think they'd be interesting not just in their respective home games, but as part of a CwDA set.


Bob Greenwade wrote on Wed, May 15 08:42 PM UTC in reply to Lev Grigoriev from 04:30 PM:

I corrected the XBetza as indicated.

And I'm pleased that the model triggered a positive response. It's what I was aiming for.


Lev Grigoriev wrote on Wed, May 15 04:30 PM UTC in reply to Bob Greenwade from 03:33 PM:Good ★★★★

I wasn't sure I could get an effective model for this, but I thought I'd give it a shot. I think the result is of a decent caliber.

Yeah, the model is effective and turn-able. Caliber is kinda acceptable.

I'm not sure I got all the letters in the right order in the last section, but I've no doubt someone will chime in if I messed it up.

It’ll be fW4bWsmWsmpafabcduW. It’s the first time when I fix XBetza because I know where my Shieldholder with such a technic is coded, and taken that code (though then added d to make it push all pieces)

Generally such a technic of pushing is like switching bullets in revolver:

(Yesterday's PotD; I had a very full and tiring day.)

301. Bullet. This piece of Lev's is one that I've categorized as "technically a spear," though its truncated forward move makes it more of a Shogi-like piece. It slides normally up to four spaces forward, or steps one space backward. It also can move without capture one space sideways, though if the space is occupied and the next one over is not then it can push the occupying piece into the unoccupied one beyond. (fW4bWsmWsmpafabcduW)

On a particularly large board (at least 16 rows), this might even be usable as a Pawn.

I wasn't sure I could get an effective model for this, but I thought I'd give it a shot. I think the result is of a decent caliber.

Thanks! :)

Aand you've rederived these pieces as a back‐formation ;‌) These are the original (long‐ and short‐, respectively) non‐helical switchback rhinos as proposed by Gilman (and independently by KelvinFox).

Actually never mind, these are two of Gilman's four: Long‐switchback Rhino and Short‐switchback Mirror Rhino. The other two move the same but with the non‐alternating step first.

Note incidentally that Gilman's ‘rhino’ is this one (specifically the sliding version), not the (modified) GA one as popularised by Jean‐Louis (hence why both forms are referred to by that name). The fact that both begin W‐then‐F is coïncidence

Rocket, which is square interpretation of Zip on cluster cell in Rocket Chess, which is mentioned earlier, moves as following:

In other words: forward Rook, forward sidemost Zip, backward narrow Electrician.

Otherwise it has a simpler version which is forward Rook, backward Bishop and forward sidemost Nightrider:

Well, then, maybe an army with my sillier pieces can be the Greenwade Goofballs. :)


HaruN Y wrote on Sun, May 12 06:18 PM UTC in reply to Bob Greenwade from 02:23 PM:

I was thinking about having Gridiron in the name of the army but then I remembered a chess variant called Gridiron Chess where the pieces cannot move vertically. I've already edited my previous comment & put your name on this army.


Bob Greenwade wrote on Sun, May 12 02:23 PM UTC in reply to HaruN Y from 02:49 AM:

I've also had the Linebacker Pawn, and the Left and Right End Pawns (those two haven't been in PotD yet, but they are described in Dealer's Chess). I know CwDA doesn't generally change around its Pawns, but they're something to look at.

I've also been toying with a couple of other ideas for American football-inspired pieces.

I think, too, that I'd rather call these the Gridiron Gamers. If you're going to put my name on it, I'd rather it was some of my sillier ideas like the Gerfod, the Springer, and the Portable Hole (not necessarily those specifically, but ones like them).


HaruN Y wrote on Sun, May 12 02:49 AM UTC:

Hope you don't mind me doing this again, but your American Football pieces gave me an idea for another CwDA.
