bronkenstein: And now on the moves (i will try to remember his key comments since i havenīt got the book here , and some time has passed since i have read it last time).
9.a4 very usefull move, letting bishop on the best diagonal available (a3-f8 that is ) and having possibility to go a4-a5 sometime later.
11. ... Nc6 ! , sacrificing c5 pawn, black would return it fast with an excellent position .
14. Bf3 Ng5 ...Smyslov probably expected draw by repetition here ( Be2 Ne4 Bf3 Ng5 etc ) but ... 15. Bc6 !
18. 0-0 (18. d:c5 b:c5 19. B:c5 N:f3+ !? followed with 20.Qh4+ might be unpleasant ... ).
20. d5! ... Soon white will have 2 passed pawns in the center , giving him decisive advantage, since black neither can move his passers on the queens flank ( they are under fire and will be blocked on the black squares eventually , the black squared bishop that black exchanged for white knight in the very opening is missing...) nor can he block white pawn mass in center (due to strong white black squared bishop on the board ) .
28. Qd2 , with Bc3 to follow and black pawn mass is blocked .
32. Ra2 ... Black is helpless.
33. ... b4 !?, a desperate pawn sacrifice , trying to break black squares blockade and gain some activity , but the game is already decided.
41. Ra8+ ... Time trouble is over, and black resigned . And indeed, what can he do against simple advance of the white pawn center ?
˝ The game was played in the very style of Capablanca ! ˝
