Game 106 in Wilhelm Steinitz’s The Book of the Sixth American Chess Congress (1891), printed pages 138–139.

1. 11.d5 There is no reason yet for changing his strategical disposition of forces and simply keeping the two centre Pawns well protected. As a rule, neither of White's KP or QP should advance unless the opponent play the corresponding adjoining Pawn two squares. Thus, in the present instance, White should have waited with the advance of P—Q5 until Black played P—K4. As it is, Black obtains good entrance at K4 with his pieces, which become troublesome to White's position.
2. 17.bxc4 By far better was 17 KtxP, and if 17...KtxKt; 18 RxKt, 18 B—R3; 19 R—R4, etc.
3. 19.Rf3 The Rook is useless on this row. B—Q3, in order to play R—QKt sq. soon, was the correct plan.
4. 19…Bb2 This and the next two moves of Black are high style of Chess in the conduct of the Q side attack.
5. 24.e5 A desperate effort to retrieve a game that is already seriously compromised. He could not, however, save the QBP, for if 24 Kt—Q2, 24 KtxP; 25 RxKt, 25 Kt—Kt3, and wins.
6. 26.Rxc4 He was bound to give up the exchange anyhow. If 26 Q—Q sq., 26 P—K5, followed by B—Q6, also wins a Rook for a Bishop.
7. 30.Nc6 His game was untenable, but of course it did not improve matters to give up a clear piece in addition to the material already lost.
8. 39…Nd5 For, wherever the Bishop may move to, the reply R—Kt7 wins another clear piece.
