'Mate' is for positions with white to move, 'mated' for positions with black (the bare King) to move. Mated-in-0 means black is already in (check)mate, mate-in-1 means white's (best) move will terminate the game. The number in those columns is the number of positions from which the result can be forced in the given number of moves (3rd column). There is no mate-in-0, but the logical successor of mate-in-1 would be positions where white can capture the King (which would be illegal in a variant with a checking rule), given in the fore-last row.

The final row gives the total of the columns, expressed as a fraction of the total number of pseudo-legal positions (= ignoring any checking rule, but without multiple pieces on the same square). For generally won end-games the left will be close to 100%, but the black-to-move fraction will be much lower, because of positions where black can capture a King or an unprotected piece. For generally drawn end-games the right number will be close to 0%, but the left number will be much higher because of King captures, and can be over 50% if white has a strong piece.

K+2B can only draw.

Acording to the rules of the game, first white has to place it's two gating pieces behind. Then black his two. I got stuck while trying to do both move in the same turn. I have tried using continuemove, but I get into infinite loops no matter what I had done.

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.

I tried it. It does not checkmate

But with shuffle.

How about Three-Toed Box Turtle?

Hi Rose. I like this game! I have one question though. You said, "Queens have the movement options of both rooks and bishops" — I cannot quite understand that, as a Bishop (in this game) cannot access any square that a rook cannot. Could you please clarify? Thanks :-)

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).

I cannot quite understand that, as a Bishop (in this game) cannot access any square that a rook cannot.

At least Bishop can jump while Rook cannot.

Also you can favorite the game as I did.

KNS is about 11 Pawn.

What's the game under discussion here? (I'm seeing this discussion on the Sign In page.)

130 if I understand it right

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.

best I've done I think is brFlDfsNlAfHblFXlbDYbrNY

Longest checkmate is indeed 130 moves, but there are only very few positions where this piece can force checkmate. Only 38.4% of the positions with the strong side to move are won (and immediate King capture already contributes 18.4%). So this is not a piece with mating potential. (For comparison: with the Wildebeest, which cannot even force mate in 2, white on move already wins 24%.)

I cannot find an Interactive Diagram of this game. I'd like an example of implementing a rules like cannot capture other cannons or other cannon types or cannot jump other cannons or cannon types. Emphasis on the plural as I need a list of pieces not just one.

Thanks for your comment! I'm glad someone else enjoys this variant.

If you're into even more complex games like the one you created, which seems pretty crazy to me, I suggest trying the sub-variant of Banzai. I haven't settled on a name for it yet (that's why there's no page about it at the moment).

Basically, everything remains the same, but you can push multiple pieces with a single move instead of just one. You'll be amazed at how this single change not only increases the complexity but also enhances the enjoyability of the game.

I was thinking of calling it Zero Gravity Chess, abbreviated as 0G, but I'm still not sure about the name. Any suggestions would be greatly appreciated!
