KEG: This games looks like a case of Chess Amateur vs. Chess Professional. Tarrasch had a won game after 11...c6? and never gave Mortimer a ghost of a chance after that. Tarrasch did nothing spectacular in this game; he just exploited Mortimer's weak play efficiently and effectively. 1. e4 e5
2. Nf3 Nc6
3. Bb5 Nf6
4. 0-0 Nxe4
5. d4 a6
 click for larger viewMore usual is 5...Nd6, but the text which was later played by Tarrasch himself and later was a favorite of Julio Kaplan and Korchnoi, and was played on at least one by Magnus Carlsen, is entirely sound. 6. Ba4
6. BxN is arguably better, but the text has been played by Alekhine, Bronstein, Karpov, Judith Polgar, and Kasparov, so who am I to argue its merits. 6... b5
6...exd4 is also a good choice for Black.
7. Bb3 d5
8. dxe5

"Inferior"--(Tournament Book)
Indeed it is, though played on multiple occasions by both Zukertort and Tchigorin. Normal and best is 8...Be6. The text is not necessarily losing, but it seems obviously bad. 9. a4!
Tarrasch was fortunate to face 8...Ne7 four times in his career (twice against Taubenhaus, once against Tchigorin, and here against Mortimer). Tarrasch played 9. a4 on all four occasions and won all four games. 9... Rb8
Taubenhaus played 9...c5 here, which was not a success. The text, 9...Be6, and 9...Bb7 seem to be the best options for Black. 10. axb5
Even against weak opposition, it is always a pleasure to see Tarrasch's logical mind at work. 10... axb5
11. Nd4
"!"--(Tournament Book)
"An excellent move..." (Tournament Book)

The Tournament Book here recommended 11...c5 for Black, but that loses after 12. Nxb5 [or 12. f3 first as suggested in the Tournament Book) RxN 13. Ba4 Bd7 14. f3 Nf2 15. RxN Rb8 16. Nc3 BxB 17. RxB and White with an extra pawn and better position should win easily. Black's only real chance lay in 11...Nc5.
But here Mortimer played the disastrous:
11... c6?
