As well as supporting Standard Chess, SchemingMind.com also supports a number of chess variants. Chess variants are games which are similar to chess, but have rules which differ from Standard Chess to a varying degree. Sometimes the only difference is that the start position has changed (for example Chess960, or All Queens) but for other games the way in which the pieces move or capture can also be different (for example Atomic, or Suicide).
Below we present the list of chess variants available on SchemingMind. For every variant there is a page showing the rules and (possibly) hints, links to valuable resources, links to example games etc.
1. Chess with modified start position
Those games are played with the same rules as standard chess (except castling rules - castling is either forbidden, or requires special generalized definition). Most chess players should be able to play them without particular problems.
In the following games only the pieces order on the first/last line is changed comparing to normal chess:
Chess960 (also known as Fischer Random, randomized initial setup and generalised castling rules to accomodate it, after castling king and rook land where they would in a standard chess game),
Chess480 (similar to Chess960 but with "orthodoxed" castling rules, where the castling king moves 2 squares left or right)
SymmetricalFischerRandomChess (most traditional, rooks on a and h files, king and queen on d and e files),
DoubleFischerRandom (like Chess960 but white and black have different setups)
FianchettoChess (initial position of rooks and bishops exchanged, no castling)
The following games apply original initial setups:
UpsideDownChess (pawns on 7th, pieces on 8th rank)
The following games change initial material:
AllQueens (both players have king and seven queens)
FullHouse (62 pieces on the board)
2. Games with changed piece types
In the following games there are pieces not present in standard chess:
Shatranj (medieval chess predecessor, weak pieces instead of queen and bishops)
Makruk (Thai Chess, the game very popular nowadays in Thailand, Vietnam and Kambodia, also queen and bishops replaced with weaker pieces)
CrazyElephant (CrazyHouse with Shatranj pieces)
3. CrazyHouse family (games with piece drop)
The following games apply crazyhouse/bughouse concept - apart from 'normal' moves, one can also drop an opponent's captured pieces.
CrazyHouse960 (crazyhouse with Chess960 setup)
TisztaBolondokháza (crazyhouse with DoubleFischerRandom setup)
(note also CrazyElephant)
4. Suicide and losers (losing material)
In the following games one wins by losing all the material. Note: the only difference between suicide and losers is that in losers one must defend the king from checks (if possible), and being mated is also a win, while in suicide the king is just one of the pieces.
Suicide960 (suicide with Chess960 setup)
Losers960 (losers with Chess960 setup)
5. Atomic (explosive captures)
The action of taking the piece causes explosion killing pieces nearby.
Atomic960 (atomic with Chess960 setup)
6. Pieces flipping colour
The following games apply concept of changing attacked piece colour:
Benedict960 (Benedict with Chess960 initial setup)
ChickenChess (Benedict + Suicide)
Chicken960 (ChickenChess with Chess960 initial setup)
7. Unorthodox win conditions
Games with unorthodox win conditions:
ExtinctionChess (win by eliminating some kind of opponent piece)
ThreeChecksChess (first player to check opponent three times wins)
ThreeChecksChess 960 (ThreeChecksChess with Chess960 Setup))
RacingKings (Kings race, who crosses the board first, wins)
8. Unorthodox moving rules
The following games apply specific move/capture rules:
AliceChess (two boards, while moving pieces land on the other board)
CaptureChess (you must capture if you can, king is normal piece, win by capturing all opponent pieces)
StanleyRandomChess (the game with secret rules)
9. Fog of the war
In the following games opponent pieces are totally or partially invisible.
9.1. Normal chess with limited visibility
The following games apply standard chess setup and rules, reducing the visibility:
Kriegspiel (opponent pieces totally invisible)
Dark1 (opponent pieces visible if threatened, must defend against checks, win by mate)
Dark2 (opponent pieces visible if threatened, no checks, win by king capture)
BlindfoldChess (the moves are visible, but the board isn't)
9.2. CrazyHouse with limited visibility
There are currently four games which merge CrazyHouse concept with fog of the war. All games below apply CrazyHouse rules (piece dropping), in all of them opponent pieces are visible only if threatened.
DarkCrazyHouse (standard setup, dropping on any empty square, all empty squares visible if you have piece at hand)
SunTzuChess (DoubleFischerRandom setup, dropping on any empty square, all empty squares visible if you have piece at hand)
DarkCrazyHouse2 (standard setup, dropping only on visible squares)
LaoTzuChess (DoubleFischerRandom setup, dropping only on visible squares)
Note that in both DarkCrazyHouse and SunTzuChess you have good chances to reconstruct opponent position.
In DarkCrazyHouse2 and LaoTzuChess it is far more difficult
9.3. Suicide with limited visibility
DarkSuicide (Suicide with only threatened pieces visible)
