Notes by E. Schiffers.

1. 6…Bb6 Formerly this line of play was always adopted in similar cases; but latterly Steinitz and Tchigorin prefer to take the Bishop at K 3, doubling the Pawns. In a like position Tchigorin exchanged Bishops, and then exchanged the Knight by Kt to R 4 for the Bishop, obtaining a good game.
2. 14.h4 A favourite attack of Mr. Mason's, which often, as in the present game, only leads to the loss of the Pawn. (See diagram.)
3. 16.h5 B to Kt 5 would have been better, with the ultimate view of placing the Knight at K B 5.
4. 18.h6 And now B to Kt 5 would be better.
5. 26.b4 Evidently White cannot take the Pawn at R 7, on account of P to Kt 3, followed by Kt to B sq. However, a move previously, after B x P, White would have lost the Bishop, but in exchange for three Pawns, and if B x R P, P to Kt 3, B to Kt 8, Kt to B sq, B x K P, &c.
6. 31…Bf8 See note 2.
7. 42.Kxe4 Taking with the Pawn would have been better, in spite of the isolated King's Knight's Pawn.
8. 62…Kxg4 Black has now a passed Pawn and some winning chances.
9. 66.cxb5 If P to B 5, then Kt to B 2 (!), and in reply to Kto K 4, P to R 3. Either the King or the Knight is obliged to retreat, and Black's Knight can occupy Q 4 or Q 5.
