Notes by I. Gunsberg.

1. 4.Bf4 We consider this move of doubtful value.
2. 10.cxd5 We quite approve of this exchange of Pawns[ though with the Bishop placed on K B 4 it is not quite as effective as with 'the Bishop placed on Q Kt 2.
3. 13.Ne5 A clever way of defending the Queen's Knight's Pawn.
4. 17…Qh6 Black has obtained a promising attack, but he is so placed that unless he succeeds with it he will suffer loss on the Queen's side.
5. 20.Nxd5 A bold course, and showing that White must have seen a long way ahead, and satisfied himself as to his future safety (see diagram).
6. 22.Qh5 A fine move, and the key to the whole combination, which has evidently taken Black by surprise.
7. 29…Be6 This move not only protects the Pawn, but also enables White to make better use of his Rooks.
8. 30…a5 Black might have been first in the field by playing R to Q 7. If he was afraid of R to K R 5, he ought to have adopted different play on his 27th move.
9. 32…Ba2 Curiously enough this was the only square available for the Bishop. If he had played BxB, and 33. R x B, R to B sq; 34. R to R 7, P to R 5; 35. R to B 4, R to R 7; 36. R to Q Kt 4, &c.
10. 33.b3 Again cleverly played. White could not have taken the Rook's Pawn, as Black would have replied with B to Q 4, ch. P to Kt 3 was played to cut out the Bishop.
11. 33…a4 This is best, as R to R sq would have been answered by B to K 4, followed by B to Q 5, &c. Black, by giving up the Pawn, liberates his Bishop, and plans a very ingenious counter-demonstration.
12. 35…h5 An important factor in Black's plan, directed against the White King.
13. 37…Raa2 Black's carefully prepared plan has now matured.
14. 38.Kf3 A courageous reply, and the only move to win the game, for if either Pawn takes Bishop or Rook takes Bishop, Black will obtain a draw by perpetual check.
15. 42…Rh6 Black's object was, if possible, to play P to R 5.
16. 44…Rff6 It seemed necessary to keep the Rook on this file, as otherwise White plays R to Kt 5, ch, followed by B to Q 5. But it admits of White pursuing his advantage even more forcibly in a different way.
