Notes by I. Gunsberg,.

1. 5…Bb6 K Kt to K 2 is not amiss here, as Kt x B need hardly be dreaded.
2. 6…Bg4 As White intends to take Black's King's Bishop with his Queen's Knight, this move has no point. For with a Black King's Bishop off the board. White can safely play P to K B 3.
3. 10…Bg4 Black would have done better to preserve this Bishop. B to Kt 5 again is useless, P to K B 4 was permissible.
4. 12…Ng6 P x P was best. Anything to prevent the solid phalanx threatened by P to B 5. P x P would somewhat loosen White's position.
5. 16.f6 A bold and enterprising idea.
6. 16…gxf6 A difficult position. If Kt x P, B to Kt 5 would probably have followed. We should almost have preferred this way of defence, for if Black then plays Kt to K 2, White must get rid of his Queen's Bishop by B x Kt, in order to continue the attack, and this Bishop off the board would have been a point in Black's favour.
7. 20…Rd8 If Kt to B sq, the King's Bishop's Pawn could not have been successfully defended.
8. 34.Kg3 Black defends himself with considerable ability. If he had played P x P, White would have replied R x B P, getting his two Rooks into play.
9. 36…Nf4 A rather bold course. White might have prevented the loss of a Pawn by P to Q Kt 4, and it is not apparent that Black could do anything to prevent White bringing his King into the game, as the Black King cannot move.
10. 37…Ne6 Of course White's endeavour is directed towards checking with the Rook, playing R to Kt 7, thus gaining either the Rook's Pawn or the King's Bishop's Pawn. As Black has hardly any favourable prospect of preventing this, he might just as well have tried his luck with Kt x P.
11. 42.a4 If P to K R 4—38. R x Kt, P x R; 39. K x P, K to R 2; 40. K to Kt 5, P to R 5; 41. K to R 5, P to Kt 4; 42. K to Kt 5, P to B 4; 43. P to Kt 4, P to Kt 3; 44. K to R 5, P to B 5; 45. K to Kt 5, K to Kt sq; 46. K x P, and White will win. Of course Black may vary his tactics on the Queen's side, but so may also White. The foregoing should only serve as a useful example underlying this end game, how to gain the opposition. Should Black at any time attempt to play P to B 3 and P to Q 4, White must play his K to B 5, then he would be in a position to play P to K 5, and P to K 6. Black could not have played Kt to Kt 3 with any advantage, as after R to Kt 4, White would come on with his King's Rook's Pawn.
12. 43.Rxa4 No doubt the quickest way to bring matters to a crisis. White might, however, have gone after the King's Rook's Pawn by R to K Kt sq, R to Kt 4, and R to R 4.
13. 48…Nd4+ Better to have a futile idea than no ideas at all.
