Glass - Kniazer, 1951, and Special Prizes

The reporting on the 1951 Israeli championship in Davar's chess column (edited at the time by Shaul Hon) was quite extensive, and has many photograph which were later reproduced in other books (including Hon's own...). Here is his report of the Glass - Kniazer game, played inthe 8th round, with Hon's annotations. Kniazer -- who lived in Haifa -- won a special prize from Haifa's municipal government for this victory. 

The same game was later analyzed in more detail in Persitz's book of Kniazer's best games, Ha'Derech Le'Nitzachon Be'Sachmat [The Road to Victory in Chess] (1959, with an introduction by Kniazer.) The remarks are broadly similar, although Persitz analyzes in more detail. White, both agree, wrongly believed his attack on the king's side will succeed, while Black correctly sacrificed one exchange and offered to sacrifice another to make sure his attack will be first. 

Glass - Kniazer [C14]

1951 Championship (8), Feb. 1951

Annotations: Based on S. Hon, Davar 1/6/2951, p. 14 [of the Dvar Ha'Shavuah supplement].

1.e4 e6 2.d4 d5 3.Nc3 Nf6 4.Bg5 Be7 5.e5 Nfd7 6.h4 Sacrificing a pawn to open a file for the rook. 6...a6 7.Qg4 f5 8.Qg3 c5 Just like in Beutum-Czerniak, Tel Aviv 1938. 9.Nge2 Nc6 10.0–0–0 Nxd4 Kniazer looks for exchanged to have more space for his pieces, but still needs to solve the c8 bishop's problem. 11.Nxd4 cxd4 12.Ne2 Aiming at 13.Nxd4 with pressure on e6.12...Nc5 13.f3 d3 Limiting the f1 bishop further. 14.cxd3 Bd7 15.Kb1 Rc8 16.Nd4 In order to prevent 16...Ba4, with many scarificial threats. 16...Na4 Kniazer is on the prowl. 17.Nb3 a5 18.Be2 0–0 19.Bh6 Rf7 20.f4 Threatening Bh5.20...Bf8 21.Bh5 Qb6! 

Now Black's plan is revealed: he prepared a counter-attack. He sacrifices an exchange so as to win the second bishop easily later. 22.Rc1 Nc3+! 23.Rxc3 Rxc3 24.bxc3 a4 White can cause no harm on the king's side, while Black has a crushing attack on the queen's side - with the assistance of the two bishops.

25.Kb2 axb3 26.axb3 Ba4 27.Bd1 The rook stood en prise for six moves -- and was not captured. 27...d4! 28.Bg5 dxc3+ 29.Ka1 Bxb3 30.Bxb3 Qxb3 31.Qf2 c2 White resigns (0–1) due to 32.Qa7 Ba3 33.Qd4 Bc1! and mates.
