(White lo move)

Chekhover

Budo

Being behind in material, White should doubtless have played for attack by P-B5. Instead, he embarks on a. faulty combination:

36 PxR RxRch

37 QxR QxR

And White resigns! For if 39 Q-K8ch, K-Kt2; 40 P*Q8(Q), Q-B8 mate: whilst, if 40 K-Ktl, KtxP etc. or 40 K-KI.2, KtxPch; 41 K-B2, Kt-K3 etc.

The Alekhine-Chatard

Attack

IN THE FRENCH DEFENSE (Part IV)

By S. Belavenets and M. Yudovjch

(For previous articles in this series, see January. February and March issues oj The Chess Review.)

We now come to Variation D: 6 . . . P-QB4 (after the moves I P-K4, P-K3; 2 P-Q4, P-Q4; 3 Kc-QB3, Kt-KB3; 4 B-Kt5, B-K2; 5 P-K5, KKI-Q2; 6 P-KR4).

This move (6 .. . P-OB4) has been the most -popular mode of defense in the past few years of tournament play; for example, in the Moscow 1935 Tournament, it was adopted invariably against this attack-and with fair results for Black. Still, we believe that by correct and energetic play, White can obtain a clear advantage. He has two ways of proceeding: I 7 Kt-Kt5? and 11 7 BxB!

Variation I

This involves a number of dangerous tactical threats; hut by playing exactly, Black can render the attack harmless.

With a view to giving up a piece for three Ps; this continuation which has been little analyzed, is very strong.

9 BxBch 0x8

But not 0 . . . KxB; 10 Q-R5.. KtxP (White threatened Q-Ktoch as well as QxP mate): U KtxBch, QxKt; 12 QxKt (Pimenov-Zagoriansky, Trades Union Congress 1937) and White won quickly.

10 KtxB Q-Kt5ch

12 Kt-Kt.5, P-Q6; 13 K1-B3, P-Q5; 14 Kt-Kl, Q-Kifich: 15 P-B3. QxP with an obviously good game lor While.

11 Q-Q2 QxP

12 R-Q1 KtxP

Black has three Ps for a piece with a promising position; note that White cannot play

The premature character of 7 Kt-Kt5? is demonstrated even more convincingly by the more positional reply 7 . . . P-B3.

The aggressive 8 B-Q3 is surprisingly refuted by S . . . P-QR3! after which material loss is unavoidable for White; for instance 9 Q-Roch. K-Bl and White's center crumbles, or 9 B-R6, K-Bl and there is no effective continuation of the attack. Hence White must resort to the text—but in that event « P-KR4 and 7 Kt-Kt5 have been robbed of all logical import.

Black has an easy development now. hence

White must, undertake something.

This beautiful P sacrifice prevents White from getting out of his difficulties.

Diagram V

Here are some likely possibilities:

I 11 PxKP, QxKt; 12 PxKt, QxB; 13 QxPch. K-Rl; 14 PxB, QxPch; 15 K-Ql. QxBch; 16 KQ2, Q-B5ch with advantage to Black.

II 11 BxP, Kt-Kt5: 12 KtxR, KtxP; 13 Q-K2, B-Kt5; 11 Kt-B3. KtxR with advantage to Black.

III 11 BxP, Kt-Kt5; 12 B-Kt3, B-Q3! 13 KtxR, BxB: 14 PxB, RxBch; 15 KxR, Kt-K6ch etc.

Variation II

So we see that after 7 Kt-Kt5? Black gets a good game with 7 . . . P-B3 (to which Ryumin first called attention in 1936). Black's problem is much more difficult after 7 BxB (see Diagram VI). Black must now recapture with the K, for if 7 . . . QxB; 8 Kt-Kt5 and Black must sacrifice the exchange without adequate compensation, 8 . . . O-O; 9 Kt-B7, KtxP; 10 KtxR, PxP; 11 QxP, QKt-B3; 12 Q-Q2 or 9 . . . PxP; 10 KtxR, Q-Kt5ch; 11 Q-Q2, QxP; 12 R-Bl-with advantage to White -in either event.

Bui; even after 7 ... KxB, White obtains the edge by <S P-B4, PxP; <) Kl-Kt5, Q-Kt3; 10 QxP or 9 . . . Q-Rlch; 10 Q-Q2, QxQch; 11

Diagram VI

KxQ etc.; White has a strong grip on his Q4 and can advance effectively on the K side.

in his analysis in the Tournament Rook of the game at Moscow 1935 between Levenfish and Menchik, E. L. Rabinovich recommends the following line of play as best for Black (see Diagram VI):

In our opinion, this "stereotyped" position is much in White's favor. The simple move 13 P-B5! menaces Black with immediate disaster, for if 13 . . . P-KR3; 14 Q-B4 threatening 15 P-B6ch as well as 15 RxP.

Thus we see that 6 . . . P-QB4 does not satisfactorily solve Black's difficulties. There is only one move which serves the purpose, namely 6 . . . P-KB3. For a long time it was considered antiquated, but was successfully revived in the games Panov-Belevenets and Panov -Yudovich (Tiflis 1937).
