Now, with regard to the 'Champion' from Omega Chess: In fact, its movement is different, slightly different. The Champion partakes of the Wazir movement, not the Ferz. Here is our Champion:

I'm able to say this quickly because I once made the inaccurate comparison myself and stood corrected myself. However, I'm very glad you mentioned it because as you can see, it is a very close relative and also, in my opinion, a very sharp piece.

While I share some of your frustrations with Omega Chess, the Wizard piece does not belong on a shortened board of the type you suggested unless it becomes a multipath-camel-ferz, in which case you may have an improved variant.

When it comes to the Champion, I do not believe any credit to Betza is necessary. Regarding giving Betza credit, I don't know whether he himself was aware that he sometimes reinvented the wheel with pieces such as the 'Waffle' which was for hundreds of years known as the Phoenix in large Shogi variants such as Chu Shogi.

Probably Champion is a lot more powerful because it is not colorbound.

I got your e-mail about the Templar and you are correct about the piece. I did not know about Betza's piece but I actually considered giving the Templar the Alfil jump. I decided against it because combining the Ferz and Alfil moves for one piece seemed less intuitive to me. And I also wanted the Templar to be worth about the same as a Rook--and Zillions already gives the Templar a higher point value than the Rook without the diagonal leap.

Thanks for filling in some of the blanks for me, George.

Yes, it's not a surprise to hear that Betza may have anticipated the FWD
and you pose a good question about precedence here.

Since as Ralph Betza points out in 1996 articles, millions of Chess pieces
are possible, and CVPage has only, what, 8000, 10000, 15000 variant
pieces, we could well expunge every one of those 15000 and still have
endless discussions on the remaining 990,000 possible pieces. Fantastic.
No more Wazir, Ferz, Immobilizer, Half-Duck, Flamingo, Nemel, Scorpion,
none of them. Never again Promoter, Venator, Quintessence, Rhino, Dragon, or Nemeroth. If you want to reference a one-step Rook, formerly called
Wazir, now dis-allowed, just find another suitable pathway for it. New
pieces, reaching the old Wazir squares, are innumerable. One, the
Earthquake, goes 13 forward 12 diagonally, and twelve cross-horizontally;
and so on for as many pieces as you want and all the time in the world.
(Betza was not original with that, as David Pritchard says in Intro to
1994 ECV that millions of coordinate pieces alone are possible)

The doublemove ferz (single capture, without Null move) is the same piece as the Free Padwar in JETAN. The Free Padwar movement diagram comes from a loose interpretation of the rules of JETAN, as given by Edgar Rice Burroughs. The Jester is the same piece, with a special initial move added. I have called the Free Padwar a 'War Elephant' in three of my chess variants.

Piececlopedia: Boyscout / Crooked Bishop 
provides another way of looking at this piece, as a combined 
[Bishop + Crooked Bishop], limited to moving 1 or 2 squares.

Larry Lynn Smith's various websites and email addresses seem to be no
longer working. I haven't gotten his homepage in over a year. So the
links in his Jetan rules are no longer operative.

Dai Shogi has the Hiryu (Flying Dragon), a two-step Bishop, and the Kirin (Kylin), moving like a Ferz or a Dabbabah. Combining these two pieces piece gives us a Templar. So we should consider the possibility that the Templar appears in some (even larger) Shogi variant.

Earlier in this thread, I mentioned (and diagrammed) Champion (or Betzan WAD, which has priority) from Omega Chess. As the Templar is to the FAD, the Fye'tin is to the Champion (Fye'tin is from Gifford's new Disintegration Chess). Both go to the same places, but the templar and fy'etin are slightly weakened. Can the fye'tin and the WAD also both be found, under different names, in some ancient shogi variant?

Just a note: Fye'tin is written this way (Fye'tin)... I noticed the
apostrophe misplaced in the other comment.  Of course, if it turns out
that there is an ancient piece like it we would switch over to that
ancient name.

Let the Grand Knight have the combined moves of a Wazir and a Knight. This color-alternating piece is called a Brigadier in veSQuj and simply a Knight in Opulent Chess. In Achernar the Grand-Horse moves like a Grand Knight and can also make 'CH moves'.

I am going to use the name Grand Horse here for a piece combining moves of a Wazir and a Chinese Horse (Mao). This non-leaping piece moves to precisely those nearby squares that the the Free Padwar cannot go to. [EDIT] This piece is a short range version of the Rhino.
