Notes by S. Tinsley.

1. 6.Be3 The opening is commonplace and dull, and it seems a pity nothing better can be suggested for White here. The move made, B to K 3, is too common, and it is obvious Black can take the Piece without danger (as here), doubling White's Pawn; or he may allow White to capture the Bishop and double his Pawns. Again he may safely retire to Kt 3.
2. 14.Rf2 On general principles Q R to Q sq seems to have its points; but White is naturally anxious to keep hold of the Queen's Rook's file.
3. 16.Kh1 Apparently waiting, and to avoid a ' pin.'
4. 16…Rd7 Not P to Q 4, to which White replies Q x K P (!).
5. 22…Re8 Again, not P to K Kt 4, to which the reply is Q x Kt P; 23. P x Q, R x R, ch, &c.
6. 34.R5f2 It is here that the game, after exemplary patience and skill on both sides, begins to assume interesting features, and it should be observed how tenaciously Herr Lasker sticks to this small advantage on the Queen's side.
7. 35.Ng3 Kt to Q B sq, with a view to P to Q B 3, would be bad in the end, the reply being Kt to B 4 with a treble attack on the Queen's Pawn.
8. 39.g4 The first really poor move, giving Black an opening of which he promptly avails himself—the 'hole' at B 5.
9. 42…c4 At last the attack by Black begins to tell. If Kt P x P, Black gets in by Q x Kt P.
10. 46.Rb1 He could do nothing by 46. R to Q sq, P to R 3, &c., because of the mating position left at home.
11. 50.b4 Most ingenious. If P x P, the Rook is shut out for the time, and White has the Rook's file open as well as the Queen's file, with slight attacking chances.
12. 53.Nc4 Defending his own Pawn and threatening to win Black's by R to Q R sq. It was this consideration which compelled Black to exchange at the 51st move, in spite of its bringing the White King more forward, for he must have his Knight available for the Queen's side.
13. 53…Ne6 Clever, and prepared by his 51. He can play his Kt to Q B 4 if necessary, attacking the now undefended King's Pawn and afterwards go to Kt 2. If 52. K to B 5, Kt to Q 5, ch, closing the files long enough to avoid the threatening mate after 53. K to Kt 6.
14. 62…Kg8 Not R x P, for then White draws at least by R x P, ch, the position being a stalemate if White K x R.
15. 67.Ra7 R x P leaves a mate on the move!
16. 73…f3 Black cannot win by R to K 2, on account of K to Kt 6, threatening mate.
17. 74.Rf5 A simple retreat to K sq would have left Black nothing except a drawn position.
18. 76…Rg7 Playing instantaneously, Herr Lasker missed the win which to his score was so important. The Rook is won in two moves by R to R 7, ch, followed by R to Kt 2, ch. The game affords many examples of Mr. Mason's splendid defensive powers in difficult situations.
