Surprisingly the tournament does not appear in the "usual" sources (i.e., Chessbase's databases, chessgames.com, etc.) Davar reported on the tournament, by its chess column editor, G. Palai. The game Stalhberg - Rudy Blumenfeld reached this position:
21... Qh4 practically the winning move, threatening not only g4 but mainly Be5. White must exchange queens and lose two pawns. 22. Qg3 QxQ+ 23. hxQ Rxe4 threatening BxN+ winning the bishop. 24. b3 Bxg4 25. Rbe1 RxR 26. RxR Bf3! Not content with a two pawn advantage, Black weaves a mating net. 27. Kf1 Kg7 White resigns (0-1) due to the unstoppable R-h8-h2 etc. One of the shortest and most decisive games in the tournament.
Unfortunately the score up to this point is corrupted. As printed, it is the impossible:
1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 d6 5. Be2 c5 6. d5 Qa5 7. Qd2 a6 8. f3 e6 9. g4 exd5 10. cxd5 Re8 11. Nh3 h5 12. Nf2 hxg3 13. fxg4 b5 14. 0-0 b4 15. BxN BxB 16. Nd1 Qd8 17. Ne3 Nd7 18. Nc4 Ne5 19. Rab1 NxN 20. BxN Bd4 21. Qf4.
Can anybody reconstruct the actual game -- or find more games? (I do not currently have at hand Shachmat from 1964, for example, which would be the obvious place to check).
Edited 25/8/2015: Amatzia Avni informs us that, as suspected, the games (or at least most of them) were in fact printed in Shachmat in 1964.
Edited 30/8/2015: Moshe Roytman informs us that more information is found, for example, in Shlomo Kandelshein's book about Aloni.
