Squirrel. Jumps two orthogonally, two diagonally, or like a knight.[All Comments] [Add Comment or Rating]

Originally the Chariot is the sense of the Rook, it is still that sense in xiangqi (where the sinogram also means "car").

Wow, that is an obscene amount of power for an 8x8 board... I'd expect all tactics and no strategy.

Also, every piece can move like a knight except the king. Since that's the only piece not augmented, maybe give him a knight's move too so he doesn't get checkmated too easily.

In my variant, Supercharged Chess, I called this piece the "Supercharged Knight", but another name could be the "Chariot". Here is my variant:

Did you guys know that another name for a Squirrel is the Bear .... in Bear Chess. It is popular in Russia.

I am currently engaged in a massive test effort to understand such short-range leapers. It is slow going, though: there are many possible combinations of moves, especially if you drop the requirement for 8-fold symmetry. And I need at least 400 games to get an acceptable accuracy for the empirical piece value of a ertain piece type. Even then, the statistical (random) error in the piece values is about 0.1 Pawn, if I test them in pairs (to double the effect of any value difference). Your estimate seems reasonable, from what I have learned so far. 8-fold-symmetric SR compound leapers with N moves seem to have a value close to (30+5/8*N)*N, in centiPawn. That would evaluate to 640 for the Squirrel. And I expect the Squirrel to be one of the stronger such compounds, with this number of moves, because of the 'front' of 5 contiguous forward moves.

Does anyone rate these pieces?? I was thinking a squirrel might be worth
6.5 to 7.0 points -- similar to Grand Chess's Cardinal.

Agree? Disagree?

(Knight + Dabbabah + Alfil) goes back to 1683 under many names. For example, Quintessential's Centurion.

thanks for that link, i've been looking at leapers lately, until now i havn't really 'noticed' the knight/dabbaba much, it is a pretty strong piece in itself. i'm not surprised you can force mate with it .. so yeah, the squirrel is a strong piece obviously with added alfil power.

has some interesting comments on the relative values of Rooks and other pieces - with the usual Kings on an 8x8 board. Ralph Betza (gnohman) states that the Knight+Dabbabah piece can force mate when the only other pieces on the board are the two Kings. Back before Zillions existed I also studied this (very tricky) piece and concluded that a Knight+Dabbabah piece is indeed sufficient mating material. This piece is one of Betza's 'Augmented Knights' - intended to be equal in value to a Rook. Clearly the Squirrel, which can move anywhere the Knight+Dabbabah can, is a more valuable piece.

In Ralph Betza's cspigs chess, this piece is worth six points.  I'm not
entirely sure that it is more powerful than a rook.  It can cut off large
swaths of board (effectively preventing a king from entering a collumn or
row), but I haven't played with it enough to be sure it is worth the six

For instance, if the opponent's 'King' was a royal knight rather than
royal commoner, the Squirrel would be somewhat less effective than a rook
in the endgame, wouldn't it?

A fun little position, if I may.

  White- Ka2 Pa3,b2,c3
  Black- SQb5 Rg2 Pa4
 1...SQxc3 mate.
featuring a nice pin.

Eric Greenwood has used this piece in his 84-square variant 'TamerSpiel', calling it the Champion.

Here are some ideas for enlarged-move Squirrels. Some cover more ground over square cells, others use boards with different cells. <blockquote> Beaver (larger rodent of same sub-order): 3:0, 3:1, 3:2, and 3:3 combined leaper. </blockquote><blockquote> Hexirrel (Hex piece like Squirrel): Dabbaba combined with root 7 and root 12 leapers, on a hex board. </blockquote><blockquote> Cubirrel (Cubic extn. of Squirrel): Squirrel+Sexton(2:1:1)+Ninja(2:2:1)+Eunuch(2:2:2) on cubic-cell board. </blockquote><blockquote> Frairrel (Frame-only form of Cubirrel): Elephant+Ninja+Eunuch only on cubic-cell board. </blockquote>

Boris Badenov was a villian in an old American cartoon series called 'The Rocky and Bullwinkle Show'. The heroes were Bullwinkle, a talking moose, and Rocky, a talking flying squirrel.<p> So I doubt 'Badenov' gave his real name....

In reply to Boris Badenov (is this his real name or a self-deprecating
pun?), the Moose moves like a Grasshopper
( but
turns through 45º during the hop. A Squirrel and Moose would indeed be an
interesting combination of a strong short-range piece and a restricted
long-range one.

But where is Moose? I must have Moose <b>and</b> Squirrel.
