Probably the champion is stronger than a bishop.

You're welcome. I've fixed the spelling, I think.

An official comment I saw on the Omega Chess commercial page assessing the strength of the B and CH on its 10x10 board (with 4 extra corner cells, too) was that B=4, CH=4 but it was recommended not to trade B for CH (at least before endgame?). Though I take B=4 or more Pawns always with a grain of salt, even for on such a large board size, the comment fits in with my tentative values as far as having the CH estimated as less than 4, and not quite worth a B, on the larger 12x10 board size of Wide Nightrider Chess, where a B would if anything improve more than the CH in value.

As a crude rule of thumb for chess [variants] in general, at least when cleanly ahead, e.g. a pawn, for no compensation, a FIDE chess master once advised me to normally just trade piece for same piece type, rather than getting into a material imbalance, if merely by numerical point value it seemed a good idea, as we don't know enough about how such imbalances work out in practice always, but a clear pawn ahead is a clear pawn ahead.

Note to CVP editor(s):

I've now just finished submitting a preset for this variant.

The Game Courier preset has been posted.  Might I suggest, though, that you use 3 square colors.  This makes the knightrider moves much easier to visualize.  (Use "checker pattern" of "10.21." - this will alternate between the first and third colors for the dark squares.)

Regarding Champion vs. Bishop - on 12x10 the Bishop has a Betza mobility of 5.07 while the Champion is at 6.70.  These are the values when the board is at 30% occupancy - which seems to work well for Chess, but Chess starts out at a board density of 50%.  Wide Nightrider starts with a densite of 40%, so calculating the mobility at 20% may be more appropriate.  This yields 5.80 for the Bishop, the Champion still at 6.70.  The density of pices on the board needs to get down to 8% before the mobility of the Bishop equals that of the Champion, and even then the Bishop is still colorbound.  So I think there is no doubt that the Champion is stronger.

I changed the checkering pattern of the settings file as you suggested, Greg.

Regarding the value of the champion on 12x10 vs. that of the bishop, my way of estimating it gives some weight to larger board size affecting long range pieces well, while short range pieces not so well. As always, people are naturally free to feel skeptical of my (or other people's) assigned values to piece types, which in my case I write that they are only tentative estimates (derived often from unproven formulae of mine and/or other people's)..

Actually the betza mobility is what I had in mind :)! But I had not took the time to calculate.

Here are my estimates of the piece values:

Interesting. Instead of Camel, did you mean the fighting value of a king? The Camel is not a piece type included in this variant.

No, actually that is the Camel value, I just didn't mean to list it.  I was putting together the values for Janus Kamil Chess at the same time (also 12x10) so that's how it slipped in.

[1] Adding "Nightrider" and "Modern Elephant" Tags to your games, as appropriate, will help to attract more readers.

[2] My Elephant (AmD) in Shatranj Kamil (64) is one-half of a Champion (WAD), moving to eight empty Squares and attacking four of them. But you probably want a piece that reaches more than 25 percent of the board.

[3] I had no idea how rarely my King's Leap Rule appears in chess variants. I authored a Zillions of Games file called King's Leap Chess that was never "zipped" - contains readable text. I notice Contemporary Random Chess using both a strange form of castling and the (sideways only) King's Bunker Leap, which cannot move over a square that is either occupied or under attack by an enemy piece. That page also has a link to the King to Bunker Leap page, by Charles Daniel in 2009.

I've added tags extensively to my rules pages (sometimes even preset pages), as well as to many of other people's games (particularly those I know I like). There seems to be very few folks tagging pages anymore otherwise, at this point in time. A future issue might be, if everyone tags practically everything in the Alphabetical Index, we're almost right back where we started (if you see what I mean). :)

The King's Leap rule was used historically, but somehow got abandoned - maybe people were glad to connect the rooks while bringing the K to safety, while still giving the other side a sporting chance vs. the K before it might castle the modern FIDE way (or other mild deviations from it, in the case of CVs), it seems. However, in FIDE chess at elite level, even, Black cannot always take getting castled for granted, while White can pretty much, due to White's birthright initiative (I read a Grandmaster wrote such, somewhere).

In the case of my own Fast Castling rule (first used in my 12x8 Wide Chess), the CV inventions I've used it in so far have largely remained little (or un-) played - Wide Nightrider Chess has been played the most so far, yet I suspect it's mostly because a lot of people like to try playing with Nightriders. Otherwise, some sort of a King's Leap rule (like Fast Castling) is especially useful for wide board CVs (another solution is to move the rooks closer to the middle, but people are conservative about that too, besides not using conventional castling, it seems to me).

There were precedents for my Fast Castling rule. One CV had K's leap-castling in spite of pieces in-between, say on the 1st rank, while another had castling as usual, except castling through an attacked cell was allowed. Neither CV was much played so far, though. Did people balk? Maybe the CVs had other things people didn't like about them.

I have a high number of CV ideas on the drawing board, but almost all use Fast Castling rules, so I'm afraid to eventually submit them all unless a few games that use that rule become more popular first.
