(history
"Chess is a modern version of an ancient Indian game called Shatranj.
The earliest record of Shatranj is found in a Persian work called Karnamak-i-Artakhshatr-i-Papakan written in about A.D. 600.
The present-day form of chess is a little over 100 years old:
according to Hooper and Whyld's `The Oxford Companion to Chess`,
en passant capture was universally adopted in 1880,
although the initial double step for pawns dates from about the 13th century.
The most important changes from Shatranj to Chess,
expanded moves for the queen and bishop, date from about 1475.
Castling began sometime in the 16th century,
but there were many variants of king and rook placement until the modern standard was established.")
(strategy
"In the opening, try to develop your pieces more than your pawns.
Always protect your King.
Look for ways to exchange lower valued pieces for larger valued ones.
Generally, if a Pawn is worth 1 point, then a Bishop or Knight is worth 3,
a Rook is worth 5 and a Queen worth 9 points."

(description
"Pawn\
A Pawn can move straight ahead one square, or two squares from its starting position.
A Pawn captures by moving one square ahead and diagonally.
If a Pawn reaches the far rank it promotes, changing into a Knight, Bishop, Rook, or Queen.
On rare occasions Pawns can also execute a move called `En Passant`, or `in passing`.
This allows a Pawn to take an enemy Pawn that has just moved two squares.")
