mack: I simply have to post the following "Aide Memoir" which appears in the earlier versions of Pritchard's Right Way to Play Chess. It is intended to help one remember the moves of the various men, but in actual fact confuses things to the nth degree:The KING may move a single square in any free direction;
Should he succumb the game is lost, so play with circumspection!
To crossword clues a ROOK may take - it moves across and down;
If lines are clear he changes gear and really goes to town.
The BISHOP travels cornerwise if ways are unrestricted,
His diocese but half the board - the rest is interdicted.
The QUEEN may radiate at will if she is not obstructed;
Like rook or bishop, as required, her journeys are conducted.
The KNIGHT, a problem child, extends (according to decree)
To the diametric corner of a figure two by three.
The PAWN moves only forward, and but a single square;
Is promoted on the eighth rank (assume it reaches there).
Initially, however, its functions to enhance,
The pawn retains the option of a double-square advance.

There, much clearer.
