The following is the most common assignment of point values (Capablanca & de Firmian 2006:24-25), (Soltis 2004:6), (Silman 1998:340), (Polgar & Truong 2005:11).
| Pieces | Symbol | Value |
|---|---|---|
| pawn | 1 | |
| knight | 3 | |
| bishop | 3 | |
| rook | 5 | |
| queen | 9 |
The value of the king is undefined as it cannot be captured, let alone traded, during the course of the game. Some early computer chess programs gave the king an arbitrary large value (such as 200 points or 1,000,000,000 points) to indicate that the inevitable loss of the king due to checkmate trumps all other considerations (Levy & Newborn 1991:45). In the endgame, when there is little danger of checkmate, the fighting value of the king is about four points (Lasker 1934:73). The king is good at attacking and defending nearby pieces and pawns. It is better at defending such pieces than the knight is, and it is better at attacking them than the bishop is (Ward 1996:13).
This system has some shortcomings. For instance, three minor pieces (nine points) are often slightly stronger than two rooks (ten points) or a queen (nine points) (Capablanca & de Firmian 2006:24), (Fine & Benko 2003:458, 582).

Open Source Software (under development) can be used to quickly learn the grid much like the addition/subtraction math facts and multiplication tables. (see
A chessboard is the type of checkerboard used in the game of chess, and consists of 64 squares (eight rows and eight columns) arranged in two alternating colors (light and dark).
