1925: <Senor Capablanca, who left London for Havana on Monday last week, gave a monster simultaneous display on the previous afternoon at the Maccabæans Club, Oxford Street. He contested 56 games, winning 34, losing 4, and drawing 10, eight games being left unfinished, after four hours' play.

1927: <Two boys, chess prodigies, are among the competitors for the championship of London, and one of them is blind. He is Rupert Cross, a 14-year-old pupil at Worcester College for the Blind. The other is James W. Rivkine, 15, who last year defeated Capablanca. They are playing with 14 other boys at the Fourth Congress of the London Chess League, at St. Bride’s Institute, and will be at the board every day this week. Neither has competed for the London championship before, but both have won at other tournaments. Cross, like Capablanca, belongs to the imaginative school; Rivkine, like Dr. Lasker, is scientific. Cross, who plays with a set of pieces which peg into holes on a board, with alternate squares raised, won his first game, with L. Kirridge, in less than an hour. It was not an easy win, although he was clearly master of the situation from the start. Rivkine lost his game to G. H. Rowson, St. Paul’s School, after a struggle lasting four hours. > (Shepton Mallet Journal, 7 January 1927, p. 2)
