We shall now give some examples which will illustrate the struggle between a defence which is trying to hold out in its position and an attacking force which is seeking to force a decision, and first one in which the defending party (in this case White) by one thoughtless move throws away all the trumps in his hand. Haakanson—Nimzowitsch. Played in 1921.

1. 9…d6 And now after P-K4, the double complex we have been discussing will have arisen.
2. 14.Ne1 White stood well, for it is improbable that Black would have been able to force him to a decision (i.e., to P-Q5), but the rather ponderous text-move creates difficulties in his own camp. His right course was 14. Kt-Q2 and P-KB3; his Q who is rather exposed at K3 would then have had a flight square at KB2, and nothing would have stood in the way of a further holding out in his formation.
3. 15…Qe6 And now White ought to have eaten the bitter fruit, i.e., played P-Q5.
4. 22…Qxe4 Lost a pawn and the game.
