Rama: Dr Vranasek had some bite, as Z Vranesic vs Suttles, 1973 shows. But he had a terrible tournament in Amsterdam.
Spassky surprised me with 8. f4 ..., as he does nothing about black's Q-side attack. It seems black is too undeveloped to do much about it.
With 11. Qf3 ..., white does have a nice lead in development but that diagonal looks dangerous. 11. ... Nb4, demonstrates this.
The slippery Spassky plays 12. Qg3 ..., and abruptly shifts the fight to the e-file, which the Nb4 so conveniently abandoned.
The exchanges on e4 favor white. Black loses a precious developed piece, his e4 pawn blocks his Bishop, his King is in the center, and white already exerts pressure.
With 17. Rxf5 ..., white has acquired a superhighway to the black King. But then comes the quiet 18. a3 ....
If the Knight retreats to c6, 19. Nxe4 ..., follows, which black cannot tolerate. So Vranesec's 18. ... g6, is an attempt to muddy the waters which goes against him.
19. e6! ..., is a killer. If 19. ... Qxg3, 20. exd7+ ..., wins a Rook. With the Nb4 "in the bag" Boris wins two pieces for a Rook.
23. Nc5 ..., is efficient and quick. Spassky plays very sure-footedly to the final position, where black cannot avoid the loss of the exchange. Vranesic resigns.
Spassky's whole use of the e-file and the square e5 is masterful.
