Game VII of the even-terms Morphy–Paulsen match (First American Chess Congress, New York 1857) — a Sicilian Opening, Morphy (White) winning. Notes from the 'Book of the First American Chess Congress,' with the Editor's additions.

1. 6…Qxb2 Altogether unwise, since it must result in at least the loss of a piece.
2. 7.Ndb5 If he play instead— 7. B. takes B. 7. Q. to Kt's 5th 8. Q. to R's 4th 8. Q. R. to Q. Kt's sq. 9. Q. B. takes K's B., having a piece more and a better position; or if— 7. K. B. to Kt's 5th 8. Q. B. to Q's 2nd 8. K. B. takes Q's Kt. 9. Q. B. takes K's B., winning the Queen. If instead of 8. K. B. takes Q's Kt. Black attempt to bring out any of his pieces, White would move 9. Q. R. to Kt's sq., equally winning the Queen.
3. 16…f6 This appears better than moving the K. Kt. at once to Q. Kt's 5th.
4. 23…Ne7 If 23. Q. R. to R's 8th (ch.), he will lose a piece. 23. K. R. to K. Kt's sq. would have prolonged the contest somewhat, but without affecting the ultimate result.
5. 26.Ke3 Black must now submit to the loss of one of his Rooks, or allow himself to be mated.
