Two pawns stood on a checkered chess board

And sorry I could not advance both

And be one player, long I pored

And thought for as much time I could afford

To where it ended with no growth

Then moved the other, as just as fair, 

And being perhaps the better move, 

Because it took space and gave a controlling air 

Though as for that, chess books there 

Had given them both the same approve

And both that day, were equally okay

As the opponent did not play black

Oh, I kept the first for another day!

Yet knowing how play leads to play

I doubted if I should ever go back

I shall be telling this with a sigh

Somewhere games and games hence

Two pawns stood on a chess board, and I–

I moved the pawn to the square less played by, 

And that has made all the difference
