CrazyChess is the sixth program in the Chess Puzzles Series.
It's primarily a lot of fun. But it also helps consolidate one's knowledge about chess
pieces and their possible motions about the chess board.
CrazyChess plays the game which is called Loosing Chess.
Loosing Chess, often also called Giveaway Chess or Suicide Chess, is a chess variant where
the goal is to 'lose', i.e. to be left without pieces or moves. It's crazy, isn't it?
Loosing Chess is getting more and more popular, many players discover the beauty and the
deepness of this wonderful game! Loosing Chess is a very popular game among the children who
like to play chess.
Loosing Chess has several variants. CrazyChess includes three of them:
- Stalemate = Win
The traditional rules, which are also greatly preferred by most strong players, follow:
All the rules of normal chess apply, with the following exceptions:
- Capturing is compulsory.
- The King plays no special role - it can be taken, put or left 'en prise'. Castling is available.
- Pawns can promote to any piece (including the King).
- The player wins if he cannot move, i.e. he has no pieces left or his pieces are stalemated.
- Only for the boards 6x6 and 7x7: on its first move Pawn may step forward only one square.
- Stalemate = Draw
All the rules of the traditional Loosing Chess apply (see Stalemate=Win), with the following
exception: the player wins only if he has no pieces left. In case of stalemate the game is drawn.
The variant is played in AISE, the Italian Chess Variant Association. It is known there as VINCIPERDI.
- Stalemate = Count Chessmen
All the rules of the traditional Loosing Chess apply (see Stalemate=Win), with the following two
These rules are a bit unusual, but quite acceptable. They have been invented on the FICS-server,
the server with the highest Loosing Chess activity.
- In case of stalemate the win for the player with fewer chessmen (pieces and Pawns).
- No castling is allowed here.
In CrazyChess you are allowed to select 3 types of initial position:
- Standard position
It means that on the board sized 8x8 all pieces stand like in traditional chess.
Initial position on the boards 7x7 and 6x6 have a special standard.
- Random position
All Pawns stand like in traditional chess while the pieces location is defined randomly
by the computer.
Every time you start the game, computer generates a new position for pieces. Pieces of
both sides are always arranged symmetrically.
- User position
Here you can place manually any pieces on any empty squares of the chess board.
Thanks to this option, CrazyChess can solve Loosing Chess problems.
Size of the board
Three sizes of the chess board are available in the program: 6x6, 7x7, and 8x8 (depicted below).
Modes & Levels
The CrazyChess program knows two modes:
- The Play mode incorporates 7 levels of difficulty. The difficulty of a particular level
depends on three factors: the size of the board, the number of half moves (plies) a computer
personality looks ahead while thinking (fixed depth), and the time alloted for a game. The
larger the chess board, the more difficult is a play. The higher the difficulty level,
the less time you and computer have for a game. At each level you will be offered a total
of 5 games. You will not be promoted to the next difficulty level unless you have won 3 out
of the 5 games at the current level.
- In the Training mode you may choose any playing strength level of the program, using the
options Fixed depth and Time control. If you wish to use CrazyChess as a solver of Loosing Chess
problems, set up a Fixed depth on 15 and Time control - on unlimited (***).
