Najdorf's Last Serious Game -- Analyzed by Najdorf

Yochanan Afek had sent me material he had received from Herbert Perez-Garcia, who interviewed the participants of the 1996 Groningen tournament -- the 50th anniversary tournament of the 1946 Groningen event, which was the first postwar international tournament. The contestants in 1996 included all the survivors: GuimandSmyslov, Najdorf, Denker, Szabo, Christoffel, and Yanofsky. Of these, four (Najdorf, Denker, Szabo and Yanofsky) were Jews. All players involved had died in the meantime.

The videos are quite interesting, showing how, even in extreme old age, these men found great enjoyment in chess, and also in post-mortem analysis. All the videos are available here (mostly in Spanish, but some in English). The most interesting one where Najdorf analyzes the last serious game he played -- appropriately, a victory, over Denker:

A Whole new Meaning to the term "Chess in the Schools".

 
In Israeli schools, grades are not known by number but by letter; e.g., 'grade a' = 1st grade, 'grade b' = 2nd grade, etc. Most schools have more than one class in each grade, and the classes are known by number: class d1 means the 1st fourth-grade class in the school. (The numbering is arbitrary: class d2 isn't necessarily worse or better than class d1.) Typically, children retain their number throughout their school career: e.g., the children in class c4 become class d4 the next year.

I had the following conversation (in Hebrew) with a strong chess player I know. 
Me: By the way, what grade is your daughter in school?
Him: She's in the English opening.
Me: Next year the Queen's gambit, I suppose?
Him: Yes. The year after that, the Ruy Lopez.
Me: And then Bird's opening?
Him: Well, that's a rather doubtful opening, isn't it?
Me: That's what they're all like when they're 12, I've heard. 
And they say chess players live in a world of their own.

Kraidman's First (?) Published Game

In the following game, Yair Kraidman, then 25, defeated the reigning Israeli champion, Moshe Czerniak -- no mean feat for a 25-year-old playing against an IM, at the time when there were only about 100 IMs in the entire world.

A very nice tactic that wins two pawns, after which the country's champion [Czerniak - A.P.] fought on in a lost position.

From the IDF Chess Championship, 1957

The IDF's championship was started in Israel in 1951 (link in Hebrew). By the late 1950s it became a tradition. In 1957 Davar published an interesting game from the championship, between Maor (White) and Bonin (Black), which shows quite well the dangers of a premature attack -- the old rule, 'the reply to an attack in the wings is a counterattack in the center' still applies. Indeed, practically no top player plays this variation as White.

More Retrograde Analysis

We have already encountered the work of Yehuda Weisberg, who was killed in the Israeli war of independence in 1948. On 17.5.1957, Davar dedicated its chess column to his memory, noting he had 'made a name for himself in retrograde analysis'. Indeed he had.

Davar published a previously-unknown retrograde analysis problem by him, which is -- I believe -- seen here in English for the first time. (The usual caveats about originally being hard to prove apply.)

What was Black's last move?

(It's harder -- much harder -- than it looks!)

The Ruth Opening

It is probably not known today that the American junior chess champion in the 1950s, Saul Philip Wachs, (thanks for the middle name, Mr. Gaige!) visited Israel in 1955. The details of the trip were given by him in an interview to Davar, published Jan. 20th, 1956.

Wachs, the interview tells us, visited Israel as part of an intensive four-month learning tour as part of his training as a teacher. He is quite positive about Israel in general and chess in Israel in particular. He notes that he played in one serious tournament (the Jerusalem club's Hannukah tournament), three blitz tournaments, and... gave ten simultaneous exhibitions. In particular he notes -- correctly -- that Israel was developing a new generation of younger players who are challenging the "old guard" of players who were born and raised in Europe. He is especially impressed by the large number of female players, noting that in the USA one hardly ever 'sees a skirt in a chess club.' He adds, no doubt to his interviewer's delight, that the chess columns in the Israeli press are 'on a high level' and that if only 'the Israeli ministry of education and culture would pay attention to chess', Israel will have great chess success.

These niceties concluded (Wachs doesn't forget to mention some of his co-students are thinking of making aliya and emigrating to Israel, a statement that at the time was more or less expected as a formality from any Jewish visitor to the country) the interview concludes with a game between Wachs and Rosenberg in the Jerusalem tournament. Unsurprisingly, the game isn't found in "standard" databases. It is interesting that what later became known as the Trompowsky opening is named by Wachs as an opening system 'associated with William Ruth'.
