This record was set in 1936 at the Prague World Championships. The first point of the match between Ehrlich (Poland) and Paneth (Romania), two defensive players. After 130 minutes of play, the score was still 0-0. Being ambidextrous, Alex Ehrlich won the point by alternating the game from the right hand to the left hand; he got tired much less quickly than his opponent. After the second point (10 minutes), Paneth gave up. In all, the ball crossed the net more than 12,000 times.
The referee had to be replaced during the match, suffering from neck pain. One of the players offered himself a snack of bread and sausages and even started playing a game of chess while continuing to play.
Following too often excessive times (some matches of this championship lasted more than 6 hours) the “rule of acceleration” was created: if a set lasts more than 10 minutes and less than 18 points have been marked, the referee interrupts the game and the server must mark the point before the thirteenth exchange.
