🍀 Gothenburg Interzonal (1955) , Sweden
🍀 2–20 September, 1929
♻️ CHAMPION: David Bronstein | 15/20 (+10 -0 =10)
▪️ The Gothenburg interzonal tournament was played between 15th August and 21st September 1955. It was a 21-player round robin, with the top nine players qualifying for the Amsterdam Candidates (1956) tournament. The winner was Bronstein with 15/20 (+10 =10 -0), Keres was second with 13.5, Panno had 13, Petrosian 12.5, Geller and Szabo each had 12 and the other qualifiers were Filip, Pilnik and Spassky with 11. Just missing out with 10.5 were Ilivitsky and Pachman.
▪️ Of particular theoretical note is that the 14th round saw three unsuccessful tries of the novelty 9 ... g5 10. fxg5 ♘d7 by players from Argentina when three Soviets tested their sacrifices in the move-order
1. e4 c5 2. ♘f3 d6 3. d4 cxd4 4. ♘xd4 ♘f6 5. ♘c3 a6 6. ♗g5 e6 7. f4 ♗e7 8. ♕f3 h6 9. ♗h4,
so the so-called Vespers - (Argentine or Göteborg) variation - with the main continuation being 11. ♘xe6 (11. 0-0-0 saw the game Rodolfo Cardoso vs Fischer, 1957 0-1) 11 ... fxe6 12. ♕h5 ♔f8 13. ♗b5 - and remained under a cloud for more than 2 years, until Paul Keres suggested the improvement 13 ... ♖h7 which was later played in Gligoric vs Fischer, 1958 1/2-1/2 and resurrected that Sicilian, Najdorf (B98) line.
