Petrosian vs Keres First Piatigorsy Cup 1963 both of the games they played ended in a draw, maybe they already decided to play for a draw from the first move as the games ended in no more than 30 moves.
Keres and Petrosian shared first place 8.5/14 with Najdorf 7.5/14 in third.

▪️ The tournament ran from the 2nd of July to the 30th of July 1963 in Los Angeles, USA. The players met in a double round all-play-all and the joint winners Petrosian and Keres returned to the Soviet Union with more than half of the $10,000 prize fund offered by the Piatigorsky Foundation. This tournament was the strongest to be held in the USA after New York 1927.
💢 The main source for this collection was the First Piatigorsky Cup tournament book edited by Isaac Kashdan.

"A player can sometimes afford the luxury of an inaccurate move, or even a definite error, in the opening or middlegame without necessarily obtaining a lost position. In the endgame ... an error can be decisive, and we are rarely presented with a second chance."
