|Raphael Persitz, Davar, 16.4.1954|
Shortly after the end of the international tournament in Hastings... the winner, C. H. O'D. Alexander, fell pray to the young Israeli master Raphael Persitz. Two weeks later Persitz defeated one of the top English masters, Jonathan Penrose, in the following game...the interesting thing here is that neither of these games are mentioned in the "standard" databases (e.g., Chessbase 9, or the Interent database http://www.chessgames.com/). (Edited to add: the Persitz-Penrose game is found Chessbase's 11 Mega Database, see comments). This, of course, is no proof of these games being "unknown": all it means is that the games were played in smaller (non-international) events.
In Davar a week later (23.4.54) we read:
Persitz's victory over Alexander had, as expected, created a stir in the English press. Alexander's victory over Botvinnik in the 1946 radio match gave him a reputation of a great player, but his victory in Hastings, and especially his sensational defeat of Bronstein, were the apex of his career and got him worldwide press. No doubt Persitz chose the right moment. At the request of many of our readers we are publishing the game.It is, indeed, an intersting game -- a nice example of mutual "pawn storms".
Persitz, Raphael - Penrose, Jonathan [C29]
