With A Pocket Chess Board

Sing a song of problems—
A pocket full of chess;
Two and thirty question marks
To make you sit and guess.
The Rooks are in the corners,
Waiting for to castle—
The Pawns are on the firing line,
Ready for a wrastle—
The Queen is on her color,
The Knights are all on deck,
The Bishops guard His Majesty
To keep him out of check.
When the board is opened,
The men are keen to start—
Isn’t that a dandy thing
To carry next your heart?
