White needs to play Дс4 and Egl, but which move should come first? When realising an advantage, close attention must be paid to the opponent's counter-chances. The natural-looking 28 Дс4? is tactically refuted by 28...Exc6 29 be Дхе5‘. 30 fc 'йхеЗ-*-, with threats of

28 Egl!
White has a decisive advantage, which he conducted to victory.
When playing a system that suits you with Black with colours reversed, you can hardly ever borrow any concrete variations directly from the normal form of the opening. On the other hand, as I hope to have shown, you can in a broad sense utilise your knowledge of the typical plans, devices and assessments. Indeed it is generally true that to acquire a deep understanding of any opening, the study of overall ideas is at least as important as the memorising of specific variations.
It sometime^ happens that to solve the problems of one opening, you make use of precepts characteristic of an entirely different system. It follows that a practical player should not confine himself to studying games played with ‘his own' openings. You should select any well annotated games for study, even if the openings are wholly foreign to your repertoire. In this way you will not be extending your repertoire directly, but perhaps some game will serve as a pointer towards doing so. The main thing is that you will increase your stock of positional ideas, resources and judgements, which, xs I have said, can be applied in the most varied contexts when appropriate. Ideas that appeal to you should be recorded in the form of ‘positional images', which we discussed during the previous session of the school.

Dvoretsky-Veselovsky (1967)
White's plan is clear: play on the qucensidc. In a suitable order, he intends Wa4, ДзЗ. Sb6/b8 etc.
In carrying out a plan, it is essential to take account of the opponent's intentions. What does Black want here? Obviously it would pay him to relieve the pressure on his queensidc by playing 17...ДЬЗ to exchange off the light-squared bishops. For this reason, the natural-looking 17 Wa4? would be a serious inaccuracy.
The bishop exchange can easily be avoided by 17 3c 1. But otherwise this move is no use to White - it doesn't fit into his plan.
The strongest continuation is 17 ДаЗ!. Increasing the pressure on the qucensidc. White simultaneously preserves his light-squared bishop from exchange. It is precisely moves like this - combining furtherance of your own plan with prophylaxis against that of the opponent - that in Nimzowitsch's view constitute the essence of true positional play.
Black only lasted a few more moves: 17...3fc8 18 o'a 4 Wc7 19 SaS f5? (19.. Sd7, with a view to 2O...d5, was more logical; I would probably have replied 20 3b8 d5 21 31Ы de 22 31b7) 20 3b8 Д.Г8 21 ДЬ4 Wa7 22 Sal <d7 23 Заб Д.Г7 24 Да5 1-0. In the final position, the
queenside domination by White's pieces is truly picturesque.

White could already have played the combination he plays next move.

To consolidate his hold on d5, White has to prepare c3-c4. 16 b3, with the same objective, would be weaker in view of 16...b5 (17 a4 ba 18 Exa4 ДхЬЗ). Now, however, 16...b5 can be met by 17 a4! a6 (17...ba 18 Sxa4 a5 19 Zeal, threatening 20 b4) 18 3dl, e.g: 18...Ead8 19 ab ab 20Ea7', or 18...Sfd8 19 ab ab 20 Exa8 Exa8 21 O'xd6; or 18...ДЬЗ 19 Wxd6 Wxd6 20 Sxd6 Дха4 21 43c 1, preparing 22 b3.

White is aiming for an advantageous exchange of light-squared bishops. 24...ФЬ7 can be answered by 25 Дс4! (with the idea of 26 h4), or by 25 43b5 and 26 Wd3.
