White obtains a free, mobile centre pawn in his KP; Black keeps it in restraint by means of the resources which he has in the K file, succeeds quite properly in killing the ‘criminal’ (See I. i. 6a, p. 12), but then comes to grief. The end game is instructive as an example of the problems of restraint in the wider sense. Carlsbad, 1911.

1. 4…Nbd7 The Hanham variation; makes development more difficult, but holds the centre. To call the move ‘ugly’ would be a question of aberration of taste. Cf. Game No. 40 between the same opponents.
2. 7…c6 By which at least Black establishes a sort of pawn majority in the centre, though it is true White for the time calls the tune.
3. 8.a4 The close character of the game allows of pawn moves in the opening.
4. 9…a6 In order to be able eventually to advance the QBP.
5. 10…exd4 Giving up the centre must not here be regarded as illogical; was happiness no happiness, because it endured for but a short time?—One cannot always be happy.
6. 11…Re8 Restraint strategy, directed against the KP. (Cf. Diagram X p. 13.)
7. 13…Nc5 The attentive student will here have expected Black to take possession of an advanced post at K4; but he wishes first to exchange; a commendable stratagem in cramped positions.
8. 18…Nd7 And now having harmoniously completed his development (though for harmony there was in truth not much room to spare in his cramped quarters), Black occupies the advanced post.
9. 19…Ne5 Commands the field. Large radius of attack. Any attempt to drive him away by P-KB4 would weaken the KP.
10. 20…f6 Observe the gradual paralysing of the KP.
11. 23…Nf7 Now—P-KB4 is prepared for. The student will perhaps ask, What has the Kt at K4 accomplished? Quite enough, since White could undertake nothing.
12. 25…f5 ‘Killing’ the paralysed pawn.
13. 26…fxe4 Overhasty; QR-K1 should have been played. e.g., 26. ... QR-K1; 27. PxP, BxP; 28. KtxB, QxKt; 29. B-Kt3, RxR; 30. RxR, RxR; 31. QxR, QxQBP.
14. 27.Ncxe4 After PxP the isolated KP would have been a bad weakness.
15. 29…Rxe1 Black has now got an equal game. 29. ... Kt-Q3 would surrender his K4 square (30. B-K5).
16. 33.Be3 This good move puts Black’s pawn majority on the Q side under restraint. Black should now have contented himself with a draw; he wished to get more and lost the game as follows.
17. 40…Ng8 Kt-B4 would have drawn.
18. 45.Ne2 Not 45. KtxKt, PxKt ch; 46. KxP because of B-Q4 ch followed by BxP.
19. 45…Bf5 It is no use, Black is in effect a pawn down; his majority is paralysed, White’s is mobile.
20. 47…Nd2+ It would have been much better to keep the Bishop at home, thus: B-Q2.
21. 52.f5+ Ingeniously turns his majority to account!
22. 52…gxf5 If 52. ... K-B2 then 53. PxP ch, KxP; 54. Kt-B4 ch would have been unpleasant.
