Chaos’s Chess
Welcoming the 3rd corrupting ‘player’
General Rules –
Set up: Regular FIDE Chess (may also be integrated into other chess variants; scroll down for “Chess Variants” section.)
After every 5* ‘Real’ player turns (Black, White, Black, White, Black; or White, Black, White, Black, White), a ghost-like 3rdplayer, Brown (or Nature), may optionally choose to take an 'In-Between' turn to perform one of the following -
Introduce a Brown/Nature’s piece onto a random square on the board
Move an existing Brown/Nature’s piece currently on the board.
Nature's pieces consist of: Nature's Queen, Nature's Rook, Nature's Knight and Nature's Bishop. (Nature's pawn and Nature's King may also be utitlized; they are described in "Advanced Rules".)
Nature’s piece may not be introduced onto a square that threatens a ‘Real’ player’s non-pawn piece. Though, they are free to be introduced onto a square threatened by a ‘Real’ player’s piece; pawn or otherwise.
Nature’s pieces can capture as well as be captured, just like a regular chess piece.
Nature’s Capture - When a Brown piece captures, the captured ‘Real’ piece doesn’t go to Nature. Rather, it’s returned to its ‘Real’ owner; who then has the option to reintroduce the piece back onto the board.
Reintroduced pieces are placed on one of the piece’s starting positions during any of the ‘Real’ player’s turn. Reintroduction counts as 1 move.
Nature can never perform Nature's Capture a 'Real' piece that would expose a 'Real' player to check.
Check and Checkmate -
If Brown makes a move that would check either or both Kings, the threatened King in question is not in Nature’s check by that threatening Brown piece until 3 ‘Real’ turns from since the last ‘In-Between’ turn has passed.
Likewise, Check restrictions that prevent Castling do not apply until 3 ‘Real’ turns from since the last ‘in-between’ has passed; until then, Castling may freely be performed.
When one or both ‘Real’ players are Nature-Checkmated by Brown, the game ends in a Stalemate. (Both armies failed to checkmate the other, and therefore, neither of them can claim victory; even if Brown Nature-Checkmates only one of them.)
Brown’s King cannot be checkmated. (Consult “Advanced rules”.)
Notes of Clarification –
Brown is not required to take an ‘In-Between’ turn after every 5 regular turns; it is merely available to him/her then. If an ‘In-Between’ turn is not taken during that turn, it is available any other turns following that. Once an ‘In-Between’ turn is taken, Brown must wait another 5 ‘Real’ turns to have another in-between turn available to him/her.
If the starting position of the reintroduced piece is occupied by a Brown or an enemy ‘Real’ piece, placing the reintroduced piece onto that starting square captures that Brown or enemy ‘Real’ piece.
Closing Word –
Your role as the Black or White ‘Real’ player is the same as in FIDE chess: to capture enemy pieces and checkmate the enemy King. In Chaos’s Chess, you must also overcome any obstacles posed by the infamous Nature, who may assist or obstruct you at random; whichever he/she chooses is completely at his/her disposal!
There are further rules to gameplay (mentioned in “Advanced Rules”) that are optional. On the other hand, you should now know the basic rules to get a game started. The rest of the instructions in this article are also important, but you have the game’s bare foundation.
