Notes by H. N. Pillsbury.

1. 7.Bxc6 In the same variation where the Black Pawn has not driven the Bishop back to Q R 4, this exchange of Bishop for Knight has been found very advantageous for White, but here the position of Black's Queen's Rook's Pawn makes a considerable difference in his favour, as he is soon able to advance all the Queen's wing Pawns, and form an early counter-attack on that side; therefore it would seem that 7. Castles, and if P to Q Kt 4; 8. P X P, P X P; 9. B to Kt 3, was preferable.
2. 8.Qe2 Q to Q 3 seems somewhat better.
3. 12…b5 See the first note. Black now threatens to win the exchange by P to Q B 4, P to Kt 5, and B to Q Kt 4; if the Queen were at Q 3, the Knight at Q 4 could cross to K Kt 3 via K 2, with a better position than it actually obtains; then the other Knight, which afterwards becomes posted at K 3, would in conjunction threaten Kt to K B 5.
4. 18…Qd7 To keep the Knight from B 5 before continuing P to Q 5.
5. 21…f5 White's attack is now brought to a standstill, and his Pieces are unable to break into the Black position, and although he has a passed King's Pawn it benefits him nothing.
6. 23…Kh8 Preparing to attack directly on the King; the strength of the Bishop at Q 4 becomes more and more apparent.
7. 29…gxf4 Black has prepared his counter-attack with admirable force, but before opening matters he should have posted his King's Bishop at Q B 2 to prevent the subsequent entry of the adverse Knight at Q 6. Had he taken this precaution it is difficult to see how White could avoid decisive loss.
8. 32.Nd6 Owing to Black's lack of precaution at move 29, the attack has in reality changed hands, and the King's Bishop's Pawn has become the focus of a powerful attack. (See diagram.)
9. 32…Qxe5 The position admits of beautiful possibilities, and Black permits himself to be out-generalled by his more experienced opponent. It was not wise to take this Pawn, and is a violation of principle to put King and Queen on the same diagonal with an adverse Bishop, and Black pays dearly therefor. It has been suggested that 32. R to B sq was the correct move, but it will not answer, e.g.: 32. R to B sq; 33. Kt (Q 2) to K 4 (the winning move), R to R 4 (best; if B x Kt—34. Kt x B, R to R 4; 35. Kt x P, Q x P; 36. Kt to Q 7, and wins); 34. Kt x Q B P, Q x P; 35. Kt x B P, R (R 4) x Kt (best; if Kt x Kt—36. R x Kt, R (R 4) x R; 37. B x P, R x R; 38. B x Q, ch, K to Kt sq; 39. Q x B, ch, and wins); 36. B x P, R x R; 37. B x Q, R x R; 38. Q x B, threatening Kt to K 6, and should win as Black’s scattered Pawns would soon fall, and he can hardly save the exchange also. But the correct play for Black was 32. ... B to B 2, and if 33. Kt x P, B x K P; 34. Kt x Kt, R (Kt 4) x Kt, with a fine game; or if 33. Kt (Q 2) to B 4, K B x Kt; 34. Kt x B, Q x P; 35. Kt x P, Kt x Kt; 36. R x Kt, R x R; 37. R x R, Q to K 8, ch; 38. R to B sq, Q to K 5, with at least a draw.
10. 33…Nh5 Not seeing the beautiful countermine of White, as Kt to K 3 still gave Black a good game, for if then 34. R to R 4, R x P, ch; followed by B X R, leaves White in a hopeless position. [Dr. Tarrasch has since given the following as the probable continuation if Black had played 33. Kt to K 3 (!):—34. R to K 4, B x R; 35. Q X B, Q X Q; 36. Kt x Q, and now although the exchange behind White has a strong attack which might be continued: 37. Kt x P and B X P, ch; or if, as best, Black replied 36. R to Kt 3, then 37. Kt (K 4) to Q 6, R to B sq; 38. R to K 2, Kt to B 5; 39. R to K S, B to Kt 3; 40. R to K 7, still with a strong attack.—Ed.]
11. 34.Rxd4 A very fine sacrifice, which forces absolute mate in a few moves.
12. 38.Rg4 A fine finish.
