International Jubilee Tournament in Bamburg
Have the Soviet players Keres and Petrosian possibly even agreed on a “non-aggression pact” regarding the awarding of the first places? It almost looked that way yesterday:

So far, no one has managed to beat Keres or Petrosian in this tournament, so the two actually seem to control the field at will. The one closer to the Soviet duo is Lothar Schmid, who with a win over Laszlo Szabo of Hungary could have benefited from the situation, as he was only half a point behind Petrosian in third place before round 13. Although Schmid had a temporary (space) advantage against the Hungarian, this was probably not enough to win the game — Szabo is, after all, one of the strongest grandmasters in the world.

The Sicilian has been known for decades as the most reliable way for Black to obtain an unbalanced but good position. Among the most popular Sicilians at the top level the two that certainly stand out are the Najdorf and the Paulsen.

The game between Bobotsov and Teufel showed once again how pleasant it is to play when the opponent suffers from a lack of space and is condemned to persistent passivity:
