Chess Strategy


After P-Kt4ch White could not play 33. K-Kt4 on account of the
pretty mate by B-B6. He would play K-R5-Kt6.

          33. PxP            Q-B5ch
          34. R-Kt4          Q-B7ch
          35. K-R5           Resigns.

A most instructive game, showing how the superior position of the
pieces can lead indirectly to a win, by reducing the opponent's
pieces gradually to impotence and compelling him to move pawns,
thereby affording opportunities for a decisive entry.


                 GAME No. 11

   White: Schlechter.    Black: Janowski.

        Ruy Lopez (compare p. 40).

          1. P-K4            P-K4
          2. Kt-KB3          Kt-QB3
          3. B-Kt5           Kt-B3
          4. Castles         KtxP

A continuation, which has lately gained in favour, is: P-Q3 and
B-K2 (see p. 39).

          5. P-Q4            B-K2

It is clearly very dangerous to gratify White's wish for an open
file by playing PxP. The move may be playable in the system of
defence called the "Riga variation" (see Game No. 17). Here it
would be advantageous to be able to close the KB's diagonal. It
is better when intending to play the "Riga variation" to have
played P-QR3 on the third move.

          6. Q-K2           Kt-Q3
          7. BxKt           KtPxB
          8. PxP            Kt-Kt2
          9. Kt-B3          Castles
         10. R-K1           R-K1

The manoeuvre cited on p. 40, namely Kt-B4-K3, which makes P-Q4
possible, is essential for the development of the QB. Black loses
the present game because White is able to keep the Bishop shut in
permanently

         11. Q-B4           Kt-B4

so that the pawn B3 should not be "hanging" when the QP moves.

         12. Kt-KKt5!       BxKt
         13. BxB            QxB
         14. QxKt           R-K3

                Diag. 114

After the exchanges the position is clearly in favour of White.
Against an undeveloped B, which also hampers a Rook, his Knight
is mobile. The Black Queen's side pawns are weak, and give White
winning chances even if Black succeeds in playing P-Q4 and
bringing the Bishop into play.  The move in the text, which
covers the pawn at B3, again prepares for P-Q4.

         15. Q-Q4           B-Kt2

The only chance lay in the pawn sacrifice by P-QB4, after which
the Bishop gets to Kt2 with a threat of mate, and the QR is free.

          16. Q-QKt4           B-B1
          17. Kt-K4

Fine play. If Black captures the pawn, White obtains a combined
attack with Q, R, and Kt, to which Black can only oppose the Q,
so that the result cannot be in doubt--e.g. 17. ... QxKP; 18. Kt-
B5, Q-Q3; 19. Q-QB4, RxRch; 20. RxR, P-KR3; 21. R-K8ch, K-R2; 22.
Q-K4ch, P-Kt3 (Q-Kt3?; 23. QxQ, followed by KtxP); 23.  Kt-Q3 and
R-K7.

          17. ...              Q-K2
