Most, if not all, names and movements already exist in countless of other variants, but combined differently.
Scacchiatopia (chess with three kings)

Would you consider somehow merging some of your game ideas with images I use in "Chess on an Infinite Plane"? I can take some of your pieces and add them on the infinite board, OR vice-versa to the 16x16 board. Then (If we can find one more person) we can play in teams?




I like your game ideas, is this correct-
If K is checked, must move out of check (if possible)
If 2 or 3 K there is no checkmate and K can be captured.
stalemate = one side has no legal moves (nobody wins).
1 K + check + no legal K move = checkmate
Correct.

The true is that all these exist and are used. The only that isn't used, is the wizard (which original name is waran and only appear in fairy chess problems).

The idea of create a party of this variant here or in another post is good and could work, and also I want to improve the images.
However I have to perfecting the rules and positions of this variant before beautifying the images, since creating such images is a somewhat exhaustive work.
Sorry for the double post, I don't know how to create multiple quotes in the same post.

Today I would like to show a chess variant of recent invention.
Scacchiatopia: a chess with three kings.
Yes, you have not read it wrong, one of the main features of this chess is the use of three kings for each player.
Scacchiatopia is a heavy variant, not extremely large but still requires a lot of concentration and more advanced planning than in classical chess.
This variant is played on a board of 16x16 squares (4 times bigger than the typical board), with 4 rooks, 4 bishops, 6 horses, 16 pawns, 2 queens and almost a dozen of new unorthodox pieces (fairy chess pieces).
The objective of create this game, is to be more slow, balanced, open and in general hard than classical chess.
Pieces of the game:
Classical:
- Pawns
- Rooks
- Knights
- Bishops
- Queens
- King: royal pieces.
New pieces: beyond classical pieces, it is added fairy chess pieces.
- Guardian: "guardian" or "mann" is a piece that moves like a king, however, isn't royal.
- Chancellor: it can move like a knight or like a rook.
- Archbishop: it can move like a knight or like a bishop.
- Unicorn: it is a piece that can move like a knight several times at the same turn, however, movements must have the same direction.
- Duke: duke will move one square in ortogonal, and next, it can move like a bishop.
- Fort: fort is the same for the duke as the rook is for the bishop. This piece will move one square in diagonal, and next, it can move like a rook; however, can't move to the direct ortogonal adjacent square.
- Empress: it can move like a queen or like a knight.
- Wizard: it can move like an unicorn or like a rook.
- Chieftain: it is a royal piece that can move like a king or like a knight.
- Pope: it is a royal piece able to move like a king or like a knight, and it is specially hard to capture.
Initial position of pieces:
Due that this are a big quantity of information, I decided to show the positions using an image:
Rules:
Rules of scacchiatopia are similar to rules of classical chess, however, some aren't the same.
- Castling: now castling is more long, however, it is only possible between the rooks and the king of the first row.
- Triple pawn movement and pawn discordance: now pawns can move three squares if these are in the second row, while can move two squares in the sixth row. This also implies that pawns of the second row could do a second initial movement when reach the sixth row. This is an effect that I called "pawn discordance" and is considered a legal movement.
- The capture in passant is annulated in this variant, due to the complexity created by the configuration of initial positions and the big board size.
- "Horse riding": "horse riding" is an special movement between the unicorn and the chieftain.
In analogy of the castling, if a player hasn't moved the chieftain nor the most near unicorn to this (in case of white pieces, left unicorn; in case of black, right unicorn), the player can move the unicorn to the chieftain and interchange the original positions of both.
- End of game: mate, stalemate, checkmate and similar rules are applied in a similar way in this variant, however, the player will win when he has checked, stalemate or captured all the kings of the opponent.
Due that now there are three kings (king, chieftain and pope), these pieces can be captured in the next movement to the checkmate (in case of not be captured, these can be used later).
Also, It is added an new possible way to win: mostmate.
The "mostmate" occurs in obligatory drawn situation due to incapacity of not repeat movements.
In this case, will win who has more kings without capture (if one player has two kings and the other only one in board, the first will win);
in case of both have the same quantity of kings, it is considered a common drawn without winner nor loser.
