Originally posted by chrspaynThere were personal problems between those two players. Alekhine felt insulted by Capablanca. This is not the first time a insult taken cost a player a tiltle chance. Lasker was insulted by Tarrasch and did not grant him a title match for many years. When he did play for the title he was older and a weaker player.
Alekhine did manage to defeat Capablanca and then wisely refused to give him a rematch despite the fact that one had been agreed on before the first match. He then refused to play in any tournment that Capablanca was playing in from then on.
