INSTRUCTIVE MIDGAME STRATEGY BY KAMAT Facing Queen's Gambit Declined. Richter. playing against Vlllard at the Munich Olympiad, lost time by the inl.neuver P-QR3 and tht impossible objective of statloninc a Kt at K5 with an old Nlemzowltsch pawn formation. Vlllard, with an excellent timing, challenged the centrally placed Kt, compelling a further loss of tempo for Black. Richter. however, unwllllni to face the inevitable, started upon a "cross attack" and landed himself, as most cross-attacks result. In a lost position br reason of aj tempo winning surprise move.
In the position diagrammed below, Black, having the move, rejected Kt-Q3 In favor of R-R3 intending to reply IS. PxKt with KtxKt; 16. PxBP, Kt-Kt5, but completely missed the fine counter-stroke. Game proceeded as follows: 14. . . . R-R3: 15. Kt-B7! (with a Black Knight ennrise. White can venture on this excursion,) KxKt: 16. PxKt, Kt-B3; 17. P-K51 Kt-Kt5; 18. BxP! KtxKP(K3;) 19. BxP i B-KB3; 20. Q-Q3. KtxR; 21. RxKt. Q-Rl; 22. B-B5! and White clinched matters brilliantly by Its 34th move. Black: K. Richter (Germany) to play Ik uss. i 'ij c m m i iff Q.J i m tow 1 f White: F. Villard (Estonia.) Analysis of the Position reveals that Black has a bad. though not a lost game at the atage revealed by the diagram. The game can hardly be said to have passed the opening stage and instead of trying to recover the lost tempo.
Black throws away more tempo-value by an til-considered premature offensive. Indeed after 14. . . . Kt-Q3: White will play 15. Kt-BS, compelling the exchange of a Black bishop for a knight and stationing pieces in advance posts, but that was because Black neglected P-QB4 to an extent seriously compromising his game. All these reveal how seemingly trifling lapses contribute toward the crumbling of the edifice indeed a hopeful feature which insures a long tenure of life for chess as internationally recognized. Mid-game strategy Is not mere combination: it is more the exploitation of minute sins of commission and omission by our opponent in the opening stages of the game. Take again the following position arrived at by faultily played Queen Indian Defense.
Indeed, we can categorically affirm that commitment of flanchetto development by Black before White has revealed the disposition of his knights is unsound and Dr. J. Cuklerman made the error of a premature queen flanchetto when his opponent had effectively rendered P-K5 by Black impossible. The opening stage can barely be said to have been over when Black was faced with such constraint that a sacrifice of minor piece by White was the natural consequence. (From Maior Open B.
