Game I of the even-terms series drawn from the 'Book of the First American Chess Congress' — a Giuoco Piano, Thompson (White) against Morphy, New York 1857. These were among the first contests publicly engaged in by Mr. Morphy. Notes incorporated from the Congress book, with the Editor's additions.

1. 6.Ne2 A manoeuvre first introduced by Mr. Stanley.
2. 6…d6 P. to Q's 4th, or Castling, would also have been good.
3. 9.Ng3 Bringing the Q. Kt. to K. Kt's 3rd, although generally advantageous, is here most unwise. Black played his King with the evident intention of presently throwing forward his P. to K. B's 4th, the danger from which is greatly increased by White's playing as in the text. We think P. to K. Kt's 4th would have been much preferable.
4. 10.Qc2 Probably with a view to the following:— 10. ... P. to K. B's 4th; 11. P. takes P., Q's B. takes P.; 12. Kt. takes B., R. takes Kt.; 13. P. to Q's 4th, &c. White, however, appears to have quite overlooked Black's 11th move of P. to Q's 4th. Instead of playing his Q. to B's 2nd, he should have brought out his Q. B. to K's 3rd.
5. 13.dxe4 White has now a most difficult game. His position is altogether exposed, whilst it is utterly impossible for him to meet the threatened danger by any counter attack. In this emergency we think his best course would have been to give up a piece at once by 13. Kt. takes K's P., since he would then have obtained three Pawns for his Kt., with, at least, temporary security.
6. 14.Ng1 Directly fatal. Kt. to R's 2nd was the only play affording the slightest chance of resisting Black's terrible attack.
