Chess T20 Rules

Board Setup

Board arrangement is little bit different in compared to standard chess. Both the kings are castled at the beginning of the game, that means king castling is not available in ChessT20. Arrangement of other pieces are also different. The arrangement of pieces are as follows;



FEN: rbnqbrk1/pppppppp/6n1/8/8/6N1/PPPPPPPP/RBNQBRK1 w - - 0 1

Moves

Moves of pieces are same as standard chess. White start first.

Capturing

Capturing of pieces are same as standard chess. En Passant and other standard capturing rules are applied.

Time Control

In standard ChessT20, each player gets five minutes. This rule can be change either by removing time control or setting a different time limit. However, if the time control is removed, the "Time Out Rule" will not be applied.

End of the Game

End of the game is declared by following rules;
  1. Completing 20 moves: Primary rule to end the game
  2. Time Out: If played with time control.
  3. Checkmate
  4. Stalemate
  5. Threefold repetition
  6. Insufficient material: This is not a possible thing to happen though.
All of the above rules are rules to end the game but not to win the game. Victory is decided by the score.

Resignation is not allowed. However rule for Resignation can be altered.

The player who has the highest score will be the winner if the game ends according to the rules above.

If the scores of both the players are equal, then the game will be draw.

Score System

A player can score by;
  1. Capturing Pieces
  2. Checking the King
  3. Pawn Promotion
  4. Checkmate
  5. Time Out (See Time Out Rule)
Points offered as following;
  • Capturing Pawn = 1 Point
  • Capturing Night = 3 Points
  • Capturing Bishop = 3 Points
  • Capturing Rook = 5 Points
  • Capturing Queen = 9 Points
  • Checking the King = 10 Points
  • Pawn Promotion = 16 Points
  • Checkmate = 50 Points
  • Time Out (refer time out rule)
If a promoted piece is captured, points are offered according to the promoted rank.

Time Out Rule

In a standard ChessT20 game, time control with 5 minutes for each player is used. However this rule can be altered. If time control is implemented, the Time Out rule works as following;
  1. If a player runs out of time, the game will be terminated.
  2. 50 points will be deducted from the player who ran out of time. If the player's score is less than 50, the score will be set to Zero.
  3. 50 points will be added to the opponent's score.
  4. Player with highest score still wins. (It's extremely rare that a player who ran out of time to win).

Win, Lose and Draw

When the game ends according to one of the End of Game rules, the player with highest score wins.
If the scores of both the players are equal, the game is considered draw.
