The banner still says "Check out Janggi (Korean Chess), our featured variant for November, 2024.". Should read "December" here, shouldn't it?

Did you find a decisive tactical thread, and if yes, against which army?

I do not like the renaming of the piece to "Lancer" because that name is already taken: Problemists have named the (2,4)-leaper lancer. The name is also dangerously close to the piece named Lance in standard Shogi.

Is it really the combination of Maorider + Moarider that you describe here

Moorider: afz(afzafz)K

Or does your description allow the rider for each step choosing again between Mao and Mao steps? A simple combination piece must choose one step pattern (Mao or Moa) for all of its steps.

Recharged Chess. Upgrades on ranks two and eight. (9x9, Cells: 81) [All Comments] [Add Comment or Rating]
Jörg Knappen wrote on Sat, Dec 21, 2024 05:54 PM UTC in reply to Bn Em from Fri Dec 20 11:05 PM:

I think I get it as such: The pawns starting from rank 1 (9) get recharged on rank 2 (8). On field e1 is the King, so no rule for row e is needed. Skipping rank 2 seems possible, but why should a player make such kind of move? This recharging is a king of gate-in where the pieces to be gated in are already present as pawns on the initial board.


Gravitational Chess. Major units fall back toward the friendly side.[All Comments] [Add Comment or Rating]

Playing around with the interactive board I start appreciating this great invention. It looks like Chess in the first sight, but it is so different!

Knights are colourbound, Bishops are colourswitching, but both pieces keep control over their original target squares, provided there is a fall-back square behind. All pieces are more powerful in the endgame compared to the normal Chess men. One rook can mate unassisted and forced, one bishop and a king mate against a lone king.

Some open questions, to one who has access to the original sources for that game:

Is castling really allowed while rooks cannot move along their base lines? It fells like cheating even more than in standard Chess.

Can rooks and queens pass a move (going one step orthogonally forward and fall back)?

Can rooks and queens capture by igui a piece in front of them ending on their starting square (can only be a pawn)?

Not knowing the original description by the author of that variant it is only a guess.

It is plain spam, in this case placed in the person information. It doesn't matter if it is placed by hand or automatically.

Usually this kind of spam consists in creating a personal profile only, and because no none notices that personal profile it is considered usually harmless. But in this instance the spammer tries to stir up attention by posting well-formed nonsense in the comments.

The moderators of this site should act appropriately.

A new nomination for a featured variant:

Separate Realms Chess by Mike Nelson and Peter Aronson.

Quote from the comments section: "A few simple rules changes have produced what is definitely a tournament-quality game." (Joe Joyce)

It has inspired two more chessvariants of myself which are among my favorites.


Jörg Knappen wrote on Mon, Jan 20 09:12 PM UTC:

Here's my next nomination.

This nomination is a bid to push the envelope of recognised Chess Variants:

Jupiter (revised) by Adrian King

A variant on a really huge board with lot of different pieces and an overwhelming number of promotions.

Or, to say it with the words of its inventor "Everything worth doing is worth overdoing"


Jörg Knappen wrote on Mon, Jan 20 09:22 PM UTC:

... and now for something completely different:

Smess

Still in the childhood memory of many people, and it is real fun to play. It also has inspired some more Smess Variants here.


Jörg Knappen wrote on Tue, Jan 21 01:29 PM UTC:

Yet another nomination:

Makruk

It is marked as recognised in the alphabetical index, but it has not yet been featured or recognised variant of the month. It is still the second most popular board game in Thailand (after Thai checkers).

Tried it out in the interactive diagram—great game with strategical depth. It took me 55-something moves to checkmate the engine.
