Kniazer - Blass, 1952.

From the same sources as the previous post, Israel Kniazer's win agains Moshe Blass. An interesting point is that while the tournament was called a tacharut amanim (masters' tournament) by Fasher and most others, Kniazer always insisted that the tournament, in which he did quite badly (2.5/9), was actually a tacharum immunim (training tournament). The two are very similar in Hebrew. 

'Training tournament' is also the name under which the tournament it also appears in Kniazer and Persitz's collection of Kniazer's games. Was this merely an excuse for a bad result? Perhaps, but it cannot be denied that Kniazer deliberately used many risky opening ideas in this tournament. 

Curiously, Persitz himself calls the tournament a 'masters' tournament' in his own, earlier tournament book (Tacharut Amanim Be'shachmat [Masters' Chess Tournament], 1953, by Persitz and Mandelbaum). The latter book reveals (p. 23) that the game took place in the third round, and adds that 6. g4?! is Keres' idea.

1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 e6 The Schwenigen variation, which gives Black a solid but passive position (Fasher). 6. g4?! Typical of Kniazer's style (Fasher). 6... a6 7. Bg2 Be7 Better was 7... Qc7. White confused his opponents, who makes many inaccuracies (Fasher.) 8. g5 Ng8? An inexplicable withdrawal. The correct move is 8...

16. Nxe6 Bxe6 17. Qxd6 Ne7 18. Qxe6 Qc5+ 19. Kh1 Qxc2 This is Fasher's score as well as Persitz's in Tacharut Amanim Be'shachmat, p. 24. In Ha'dererch Le'nitzchon Be'shachmat, p. 84, Persitz has 18.Qxc2 immediately instead. 20. Qxe5 Qxe2 21. Qe6! and Black resigned (1-0)  since mate is unavoidable without sacrificing the queen (Fasher).
