MissScarlett: Illustrated London News, October 4th 1845, p.224:<The following specimen of this remarkable game was played some time ago, between the Hon. Mr. T___ and Mr. Staunton. It is, as far we know, the only one at these peculiar odds which has ever been printed.
In this game Mr. Staunton, White, places a ring or a cap (from whence the term Pion Coiffé ) on his K Kt Pawn, and undertakes to Checkmate his adversary with that Pawn. The reader, unacquainted with games of this description, may form some idea of the difficulty of mating with a particular Pawn, when told that the Pawn in question is never allowed to be made a Queen or other piece, but must effect the Mate as a Pawn only —that if the adversary (Black) by skill or the sacrifice of his pieces, can win the said Pawn, the game is his. In like manner, if he can compel White to give Checkmate with any other piece or Pawn, or can himself, while White is intent upon the preservation of the all-important Pawn, Checkmate him — he of course wins the game.
Before playing the game over, a thimble or some distinguishing mark should be put on the K Kt's Pawn of White.>

< I. I. W., Edinburgh. — ln the Pion Coiffé, or Marked Pawn, Game the giver of the odds does not undertake to “Queen” the marked pawn. He undertakes to give checkmate with it. A game of this description, in which Mr. Staunton gave the odds of the Pion Coiffé to the Hon. Hanbury Tracy, was published about five-and-twenty years ago, but we cannot recollect where.>
