Game No. 343 in Wilhelm Steinitz's The Book of the Sixth American Chess Congress (1891), printed page 411; played May 3, 1889. Steinitz's original notes follow. The original analysis is preserved, including the illegal 29...K—B sq. in note (d), where White's Rook controls that square.

1. 11.Ng4 Kt — Q2, with the view of playing Kt — KB sq., was, we believe, preferable.
2. 14…Nfd7 Anderssen's favorite retreat for the KKt, viz., K sq., would have served Black's purpose better, as it would have given no opportunity to the adversary on the seventeenth move to effect an exchange.
3. 19…Rfe8 If 19...P—K6; 20 P—KB4 isolates the advanced Pawn which must soon fall.
4. 26…Bf5 An error of which the opponent avails himself most beautifully. K—R sq. was his best defence. If, however, 26...Kt x Kt, the game might have proceeded 27 B x Kt, 27 Q—R4; 28 P—KKt4, 28 Q—R5; 29 B—Q5 ch., 29 K—B sq.; 30 Q x R ch., 30 R x Q; 31 R x R ch., and mates next move.
5. 36.Re7+ The mating net could have been drawn tighter here by B (K4)—KB4.
6. 42.Rf7+ A much shorter and finer finish is here missed by 42 R—B4, 42 K—R sq.! (or 42...Q—B8; 43 R (B4)—B6, etc.); 43 R—B5, 43 Q—Q8; 44 B—B3, and wins.
