"Just like you, I might consider various moves which at first sight seem logical, e.g. 10...Nc6 11.e3 Re8, but what to play after 12. Be2<?> Or, 1O...c5 11. dxc5 d4 12. Ne4 followed by 13. Bg2. Nobody can be satisfied with the passive move 10...c6 because the two bishops prompt the strategic feeling that one should open the position and not block it!

The correct decision can only be made, however, after you find and fully appreciate the strength of the inconspicuous­ looking 10....Re8! which, being the only appropriate move, leaves you with a feeling of full satisfaction.

Only 10...Re8 harmoniously fulfills all the preconditions necessary to carry out a favourable opening of the position after 11. e3 c5! 12. dxc5 d4 or 11. Bg2 Nc6! 12. e3 Nxd4 or 12. 0-0 Nxd4 13. Nfxd5 c6 14. Nf4 Bg4 (which occurred in the game) with a clear advantage to Black."
