It does, however, help White build the strongest center possible, which might translate into a decisive kingside attack. At least, this is what White is dreaming about. 6... b8c6 Black, on his turn, realizes that the opponent has burned some bridges and that the pawn on c4 might well be attacked with every single black piece. More or less, this pawn is doomed, dreams Black, and he has visions of a won queenside battle. 7. e2e4  7... d7d6  8. c1e3  8... b7b6  9. f1d3  9... e6e5 Kasparov named this the Portish-Hubner wall, and my database indicates that 9. ...0-0 is vanishing. Rightly so, why castle into White's attack? 10. d4d5  10... c6a5  11. g1e2  11... e8d7 A nice novelty! The king often walks toward the queenside on its own in the Nimzo-Indian Defense, not necessarily using the castling crutch. 12. e1g1  12... d7c7  13. f3f4 Vitiugov hurries to open the center. 13... f6g4 While Oparin tries to keep everything under blockade. 14. e3d2  14... e5f4  15. d2f4  15... f7f6 White's play seems done. 16. e2d4 Not so fast, there is this sacrifice that intends to open up the black king's guard. The price of a knight to set the center in motion and open up the bishops is totally worth it. 16... g4e5 At least the knight got closer to the black king. 17. d4b5  17... c7b7  18. f4e5  18... d6e5 In any case, Vitiugov needs to demonstrate immense creativity in order to keep his initiative looming. 19. d5d6  19... a8b8  20. d3e2  20... c8e6  21. b5c7  21... e6f7 Black is just in time. 22. a1b1 Almost all the white pieces are active, but is it enough? 22... d8d7 Oparin also brings his pieces out and wants to deal with the d6-pawn once and for all. 23. e2g4  23... d7c6  24. g4e6 White bets on the power of his passer. 24... f7e6  25. c7e6  25... a5c4  26. d1g4  26... h8g8  27. d6d7 This, however, turns out to be wrong. 27... c4e3  28. g4h3  28... e3f1  29. b1f1  29... c6e4  30. h3h5  30... g8d8 This is more or less it!
