In 1967, the IDF championship took place just before the Six Day War. Two games from it, including Nagar's brilliancy, were reported in the New York Times' chess column on June 9th, 1967 -- as the war was still raging. Nagar told me in an interview in April 2010 the secret behind this most famous game of his (my comments in square brackets):
In 1967 the IDF championship was in Tel Aviv's Beit Ha'Chayal ['Soldiers' Home', a hostel for soldiers on leave]. Most of the players resided there. The latest issue of [the Israel Chess Federation's magazine] Shachmat, just came out, and featured a game between Daniel Mor and Gad Rafaeli -- not the same Lt. Gad Rafaeli from the famous song, by the way -- where Mor played the Marshall Gambit as Black. I thought I found an improvement to Mor's play.Here is the game, with Horowitz's annotations.
Sure enough, a few days later Gadi Singer allows me to play the Marshall gambit -- and he follows Rafaeli's game exactly to the critical point! I started to sweat and shake, as I realized that I am now about to make a real-live '!!' innovation over the board (18. ... Bf4!!), a once in a lifetime experience!
By the way, Dov Porat, who played in the tournament, was killed a few weeks later during the Six Day War. I probably played the last serious game of his life with him.

Spectacular... presented a multitude of knotty problems for the adversaries and annotators. White refused to capture the intruder at this point...
19. Qg2 Qh5 20. f3
...and again refused to take the Bishop after 19. ... Qh5.
Space does not permit the demonstration of the fantastic possibilities for attack and defense had White played gxf4. The line, moreover, probably had been carefully thought out by Black [true! -- A.P.] On the other hand, extreme bravado may have been the motivation.
20. ... Rxe1+ 21. Bxe1 Be3+ 22. Kh1 Bh3 23. Qe2 f5

Black mounted a fiery attack with 23. ... f5. Here, 24. Qxe3 could have drawn the reply 24. ... Re8, leading to mate or loss of the queen.
24. Bd2 f4
Equally shattering. Black's rook is ready to administer the coup the grace.
25. Bxe3 fxe3 26. Na3 Rxf3
After 26. ... Rxf3, White had only token defense.

A note about the names: "Gadi" and "Shmulik" are common diminutives of the given names Gad and Shmuel. I spelled Zinger's last name as Horowitz did, though it probably is often written (with the German 's'-sound) as 'Singer'. I couldn't find any of the players mentioned (except Horowitz...) in Jeremy Gaige's Chess Personalia: a Biobibliography, so I used Horowitz's 'Zinger' for consistency and phonetic spelling elsewhere.
