"‘Anderssen once said to me: “To win a tournament, a competitor must in the first place play well, but he should also have a good amount of luck.” I quite agree with that, but it naturally follows that there must be also ill luck in tournaments, of which many instances could be cited, notably that of Winawer, who, after having tied for first and second prizes in Vienna, and just a few weeks before he came out chief victor in Nuremberg, did not win in London a single prize out of eight (to include the special one for the best score against the prize-holders). All this would tend to show that, at least, a single tournament, especially one consisting of one round only, cannot be regarded as a test.’"
