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

Also (belated) Happy Birthday :‌)

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).

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

Appeared in 4 Double-Acts Chess.


Bob Greenwade wrote on Sat, May 11 09:34 PM UTC in reply to Diceroller is Fire from 06:58 PM:

With my supply of pieces dwindling, I'll need these. Thanks! :)


Bob Greenwade wrote on Sat, May 11 05:54 PM UTC:

298. Chained Bishop, 299. Chained Rook, and 300. Chained Queen. These are related to (and, unconsciously, indirectly inspired by) the Helical Switchback Rhino and Griffin that were suggested to me by fellow CVP contributor Bn Em for Unnecessarily Complicated Chess. Given that today's my birthday and this set leads into #300, I thought it seemed like a fitting moment.

These pieces start by taking one step in the direction 45° from what the name would suggest: orthogonally for the Bishop, and diagonally for the Rook. They then turn 45° toward the intended general direction, step one space, then make another 45° turn the same direction (left or right) as the previous one, and continue making alternating turns of two left and two right (in either order) until reaching their destination.

For example, here's the Chained Bishop (Wafs(afqafz)Wafsafq(afzafq)W):

And the Chained Rook (Fafs(afqafz)Fafsafq(afzafq)F):

The Chained Queen, naturally, combines the two (Kafs(afqafz)Kafsafq(afzafq)K).

The marking for "Chained" was tossed together as a casual experiment, and I was surprised at how well it worked, at least to my eye.

I can imagine how "Chaining" could be applied to other pieces as well -- not just compounds like Chancellor and Archbishop, but also bent sliders like Rhino/Manticore and Eagle/Griffin, or even leaping sliders like Ostrich and Osprey or Tiger and Striped Dragon. (I'm not so sure how well a Chained Nightrider would work, though.)


Bob Greenwade wrote on Sat, May 11 02:19 PM UTC in reply to HaruN Y from 06:16 AM:

Ah, that link works quite nicely.

So the basic Fairy in this case is basically WS, with that special property of making enemy pieces that target it switch sides for one turn. The swapping property of the more advanced versions are a bit more interesting, though if I'm doing a Fairy in Fairy Chess I'd want it to be more like what I proposed. (Not that the Discord version is a bad idea, of course; I may come up with something for the Fairy++ on the chart.)


Bob Greenwade wrote on Sat, May 11 04:41 AM UTC:

297. Paratrooper. There actually have been a few definitions for Paratrooper before, the most notable on this site being in Pawntrooper Chess, Invasion, and (on a rhombus board) Diamond Chess 306. All of those are quite legitimate takes, but I'm not sure that even the first two could be shown on an Interactive Diagram.

The version of Paratrooper that I propose can, by default, move two spaces in any orthogonal or diagonal direction (K2). It can also, if it's in the player's starting area, move without capture any distance along those lines, leaping over any number of pieces in the way (K2(paf)mQ).

(I just finished making this entry this morning, and my brain's been too tired to make a move diagram. I'll see if I can't rectify that tomorrow, and replace this paragraph with it.)

On an Interactive Diagram, the limitation for the longer move would be done with the morph function.

I wouldn't worry too much about the supports breaking on this; they're 3.25mm in diameter, and there are eight of them.

296. Corporal. The Corporal is the most basic "improved Pawn," moving for the most part like an orthodox Pawn except that its forward diagonal move does not require capture. (fFfmWifmnD)

I don't see this piece much, but I think the intent is that it will appear as an auxiliary to conventional Pawns.

The model is utilitarian, simple, and certaintly no less stable than an orthodox Pawn. (I based its look off the Musketeer icon for the piece.)


Bob Greenwade wrote on Thu, May 9 04:13 PM UTC:

Yesterday was such a weird day that I forgot to post the PotD, even though by the end of the day I thought I'd done it. So...

295. Quarterback. Expanding on my set of pieces with an American Football theme, the Quarterback is probably the most complex of the lot.

The piece's basic move is to any space within a two-square range, but without leaping.

It also has two options for an initial move. The first is to "jump" the front line: it can leap two spaces in any direction forward; or it can leap over any piece in one of the three spaces directly in front of it to the second space beyond that, without capture.*

The other option for an initial move is the chess equivalent of a pass: the Quarterback swaps places with any friendly piece on the board. (K2nNifhSiffNipfampfamfhKipfampfhamfKimpfapsampz(vs)amfWimpfapsampszafsmWiudU)**

At first I thought I'd need to adjust this piece and make the stars smaller, but once it rendered fully I decided that that would be unnecessary.

(As for today's piece, I'll try to get that up this afternoon.)

*In the XBetza code, I'm frankly a little unsure about the part about jumping over a piece to the second beyond, even though I tested all four parts of that and they all worked as expected.

**Probably this would be much shorter with bracket notation; my brain isn't functioning right to figure it out right now, though.

294. Cerberus. There are multiple ideas of what Cerberus would be like as a chess piece; I figure that the Cerberus move should be triple that of a Dog. However, I've found two versions of Dog, one from large shogi variants and the other by Musketeer Chess (both of which I should post sometime soon; I thought I already had). I decided to base Cerberus off the latter.

The Musketeer Dog (which I like to call Big Dog) has a move of one space sideways or three spaces diagonally; that would give Cerberus a move of three sideways and nine diagonally. The latter seems enough that it might as well be a slide. (BsW3)

I think it would be interesting to see how existing games with their own version of Cerberus would fare with this in its place.

Modeling Cerberus as a chess piece is hard; mine isn't the only attempt at it. I think it does the job, though.


Bob Greenwade wrote on Tue, May 7 04:17 AM UTC in reply to HaruN Y from 01:34 AM:

That's a possibility, if I can find a way to differentiate the piece from the regular Turtle (the move for which I still need to edit).


HaruN Y wrote on Tue, May 7 01:34 AM UTC in reply to Bob Greenwade from Mon May 6 03:50 PM:

How about Three-Toed Box Turtle?


Bob Greenwade wrote on Mon, May 6 03:50 PM UTC:

293. Three-Toed Sloth. As of this writing, fellow CVP user Bn Em has found the piece that would take the longest to force checkmate against a bare King, with only a King's help, and after looking at a diagram of its move I decided that it deserved a name, and probably some use in a game somewhere.

The choice of move is quite complex: it moves one step directly forward, or diagonally backward and to the right; or leaps two spaces diagonally forward and to the right, or backward and to the left; or leaps two spaces forward and one to the left; or makes one or two leaps of two spaces directly forward. (fWbrFfD2lfNfrblA)

Extra points (and, of course, due credit) to whomever can come up with a good name for fWblFfD2rfNflbrA (to go with this piece the way I created the Purple Finch to go with Adrian King's Blue Gecko). I think they'd be a fun addition to my Kagamigi games.

That's a rather fearsome-looking sloth, and probably needs a bit of reworking; I only just modeled it yesterday, and arguably didn't give it the time it needed (and that I normally give a piece like this) to really look right.


Bob Greenwade wrote on Sun, May 5 04:19 PM UTC:

291. Señora (Argentinian Queen) and 292. Saltador (Argentinian Knight). I actually was getting something else ready for this weekend, and then realized that I'd already uploaded another version of it, so here are two pieces that go with the Faro and Loco from two weekends ago.

To refresh, the Argentinian sliders capture like the conventional pieces, but must jump over another piece in order to move without capture. The Faro (Rook) does this orthogonally and the Loco (Bishop) does it diagonally, so naturally the Señora (Queen) does both. (cQmpQ)

The Saltador (Knight) is a slightly different story. It moves like a normal Knight, particularly when capturing, but can only move without capturing if at least one of the two spaces it's jumping past has a piece in it. (cnNpafsmK)

The Saltador looks a little weird, but then again most of my "enhanced Knight" pieces look weird because the enhancements are meant for symmetrical pieces, which Knights are not.

In other news, I'm told that the problem I was having with Thingiverse's editor has been patched up as of last Tuesday. I haven't tested it out yet; I probably will do so over the weekend.


Bob Greenwade wrote on Fri, May 3 04:04 PM UTC:

290. Threeleaper. This piece is one that I had assumed was purely a problemist's piece (or a piece used only as part of a compound, such as the Frog) until I learned that it apparently is used in a version of Tamerlane. Said version isn't on this site, so I don't know how well it works in practice, but given that it can only reach about 11% of the squares on a board (at most) it's probably not impressive.

Its move is simple: it leaps three squares orthogonally. (H)

Like I say, it can have some value; just not a lot. (Still, I was surprised when I found that I hadn't already posted it.)

Such a straightforward piece deserves a straightforward model. (And of course you can easily imagine what the Fourleaper and Fiveleaper would look like!)
