According to David Hooper and Ken Whyld, San Sebastián 1911 was "one of the strongest five tournaments held up to that time", as all the world's leading players competed except the World Champion, Lasker. At the beginning of the tournament, Ossip Bernstein and Aron Nimzowitsch objected to Capablanca's participation because he had not fulfilled the entry condition of winning at least third prize in two master tournaments. Capablanca won brilliantly against Bernstein in the very first round, more simply against Nimzowitsch, and astounded the chess world by taking first place, with six wins, one loss and seven draws, ahead of Akiba Rubinstein, Milan Vidmar, Marshall, Carl Schlechter and Siegbert Tarrasch, et al. His loss, to Rubinstein, was one of the most brilliant achievements of the latter's career. Some European critics grumbled that Capablanca's style was rather cautious, though he conceded fewer draws than any of the next six finishers in the event. Capablanca was now recognized as a serious contender for the world championship.
