HE NEXT FINAL took place rather early, fmishing on January 2, I935, so it coincided with Botvinnik's absence, as he was making his international debut at Hastings - the frrst Soviet player, not counting the 'wanderer' Bogoljubow, to be allowed to play in a foreign tournament since A. Rabinovich at Baden-Baden in I925. In his absence, Grigory Levenfish came back to the fore to share frrst place with Ilya Rabinovich in the field of 20. As the birth dates of the two winners were I 889 and I89I respectively, the result was a slight check to the progress of the younger generation.Another veteran, Bogatyrchuk, born I892, also impressed, but after him the table is occupied by the younger generation. Others of the older generation such as Freiman, born I 882, and Ilyin Genevsky were the failures of the event. The former, in particular, ruined many favourable positions.
Levenfish annotated all the games for the tournament book, a Herculean task that took him so long that it did not come out until I937. Nor was a brilliancy prize ever decided upon (the choice was too great) but this effort from the 9th round is impressive.
Grigory Levenfish-llya Kan Queen's Gambit Declined D66
1 2 3 4 5 6 7 d4 c4 lLlc3 .i.g5 e3 lLlf3 .:ct d5 e6 lLlf6 .i.e7 lLlbd7 0-0 c6 8 9 10 .i.d3 .i.xc4 a4 dxc4 a6
The Orthodox Queen's Gambit was very popular in the I930s. In the light of later analy sis one can spot inaccuracies. Instead of I 0 a4 the move I 0 e4 is considered more promising, with the likely continuation IO ... b5 I I .i.d3 h6 (l l ...b4?! I2 lLla4) I2 .i.f4 (I2 .i.h4? lLlxe4!) I2 ... .i.b7 I3 e5 lLld5 I4 lLlxd5 cxd5 1 5 0--0 .
10
11 ..td3 ..tb7 b5
This is a serious slip. The correct reply is considered to be l l ...bxa4 12 lDxa4 'iia5+ 1 3 lDc3 .:l.b8 14 'iic2 c5.
12 0-0 b4
The move indicated at the time, 12 ... h6, is hardly better. By means of 13 1.xf6!? (but not 1 3 1.h4 in view of 13 ... b4 14 lDe4? lDxe4 15 1.xe7 lDxf2!) 1 3 ... lDxf6 14 lDe4 White would achieve a clear positional advantage.
13 lDe4 lDxe4 14 1.xe7 'iixe7
Here the zwischenzug 14 ... lDxf2 doesn't work. There comes 15 ..txh7+! �h8 (15 ... <hh7? 16 'iic2+) 16 .:l.xf2 'iixe7 17 ..tbl and Black's position looks grim.
15 1.xe4 .:lacS 16 lDd2!
As a result of Black's slip at move 1 1 Levenfish has, by logical play, gained an obvious positional advantage. The pressure on the c-file and the h l-a8 diagonal, combined with the blockade of the backward pawn at c6 offers White excellent prospects in the middlegame.
16 e5
There is no other counterplay. 17 'iic2 lDf6
After 17 ... exd4 White has a pleasant choice between the quiet 1 8 exd4 lDf6 19 ..tf3 followed by 20 lDb3 and the sharper 1 8 ..txh7+ �h8 19 1.e4 dxe3 20 fxe3 lDf6 21 .:l.f4.
ts .to .:trds 19 dxe5 'iixe5 20 lDc4?!
Even experienced players sometimes cannot hold back from playing a natural move, even if it is not the best. 20 lDb3, transferring the knight to c5 (20 ... lDd7 21 1.g4!) would ensure his advantage.
20 'iic5
This retreat, as it were pinning the knight, was clearly underestimated by White.
21 e4
2 1 a5 looks more consistent. Instead White strives to increase his influence in the centre.
21 .:l.d4
22 e5 lDe8 Otherwise comes 21 lDd6.
23 :ret .:l.cd8 (D)
24 e6!?
As a result of the inaccurate 20th move by White, Black has activated his forces. If he had time to get in ... ..tc8-e6, all dangers would be behind him. Therefore White opens a second front and the play sharpens.
24 25 26 .:l.xe6 .:l.e5 fxe6 lDc7 lDd5
Kan has beaten off the immediate threats and consolidated to a degree, though the b7- bishop is still inactive, so it is premature to speak of even chances.
27 h3 .:l.f4 28 b3
Presenting Black with an outpost at c3 is undesirable, but only thus can White bring his major pieces into play.
28
29 'iid2 30 .:teet
.:l.df8 h6 30 lDe3 'iid6 gives White nothing.
30 .:l.d4
31 'iic2 .:l.df4 32 'iig6 .:1.4f6 33 'iih5 'iid4
Both sides can be satisfied with the regroup ing. White has taken the open e-file, while Black has coordinated his forces, except for the unfortunate bishop, and broken the pin of his d5-knight. 34 35 36 .:l.e8! .:l.xf8+ 'iie5! lDf4 .:l.xf8
A strong manoeuvre underlining White's advantages. The most promising form of exploiting this would be to get into an ending
40 The Soviet Championships where the Black's pawn weaknesses are
particularly vulnerable.
36 'ii'c3 (D) A clever reply. The natural 36 .. .'ifxe5 37 ltJxe5 .l:te8 would lead, after 38 <ifi'fl l:.e6 39 g3 tiJd5 40 ..txd5 cxd5 41 tiJd3 l:.xe 1 + 42 �xe 1 a5 43 �d2 �f7 44 �e3, to a textbook example of bad bishop against good knight. Now, how ever, Black threatens 37 ... 'ii'xb3 or 37 ... tiJxh3+ and the exchange on c3 is clearly in his favour. Yet White fmds a way of breaking Black's heroic resistance.
37 tiJd6!!
We quote Levenfish here: 'One of the best combinations which I have managed to create. The idea of 'diverting and overloading' had occurred up to this game only in composed positions. The main variation culminates in an ending which demanded deep analysis and the value of the whole concept is enhanced by the fact that I had to take account of a counter combination.'
37 ltJxh3+!
The passive retreat 37 ... ..ta8 is very risky as there comes 38 'ile7, threatening 39 'ii'xf8+!.
38 �h2 ltJgS! 39 ..tg4!
Obviously not 39 ltJxb7 l:.xf3! .
39 'ii'xe5+
He has to exchange queens, since 39 ... i.a8 allows 40 f4 .l:.xf4 (40 ... 'iixe5 41 fxe5) 41 'iie8+ �h7 42 i.f5+.
40 l:.xe5 ..ta8
41 f4!
The combination continues.
41 l:.xf4
There is no choice as retreating by 4 I ...ltJt7 or 4 l ...tiJh7 allows 42 i.e6.
42 ..tf5!
Here is the key to the whole concept. The rook is cut off from defending the back rank, and the murderous 43 l:.e8+ can be prevented only by surrendering material.
42 l:.xf5
Losing control. The best defence was 42 ... g6, the main move which Levenfish had to consider in working out the combination. He had in mind 43 .l:.e8+ �g7 44 l:.xa8 gxf5 45 l:.xa6 c5 (45 ... ltJe4 46 ltJc4) 46 a5 ltJe4 47 .l:.a7+ �f6 (47 ... �g8 48 l:.a8+ �g7 49 a6! ltJxd6 50 a7) 48 ltJe8+ �e6 49 a6 .l:.fl 50 .l:.h7 .l:.al 5 1 a7 and then the intriguing fmish 5 l ...'iti>e5 (what else?) 52 l:te7+ 'iti>f4 (52 ... �d4 53 ltJc7) 53 ltJc7 ltJt2 54 tiJd5+! �g5 55 l:tg7+ and mate in two!
Obviously there are various sub-variations, but in any event, the a-pawn should decide in White's favour.
Now it is a case of prosaic technique. 43 ltJxfS �f7 44 ltJd6+ 1-0 Here is another impressive combination.
Grigory Levenfish-Vyacheslav Ragozin French Defence C I6

He had to try IO ... tiJf5 I I 0--0--0 i.b6 and then ... c5.
