.We call them typical combinations because they occurfrequently.Learning them will help you become a strong chessplayer.Ifthe patterns of these combinations becomes familiar, you will not let theopportunity for a winning and striking combination slip through yourfingers.The Sacrifice on f7All chessplayers know that in the opening the f7-square is the weakestpoint in Black s camp; therefore, catastrophes are possible on this weaksquare.However, both in the opening and in the middlegame evenexperienced masters sometimes overlook the f7 blows.The combinationsagainst f7 in chess practice are quite diverse, but most of them have onething in common: White s light-squared bishop plays an important role.In our first example, White has an overwhelming advantage and he bringshis White-squared bishop into play.156.

Black resignsMate in two follows 2.& Kxe6? by 3.Qd5+ Kf6 4.Qf5 mate, otherwiseWhite wins the queen.Sacrificing a Bishop at h7In the ancient Polerio manuscript we find the following position:161. Diagram 156White to moveAfter 1.Bxh7+ Kxh7 2.Ng5+ Kg8 3.Qh5 Bxg5 4.hxg5 f5 5.g6 or 2.&Bxg5 3.hxg5+ Kg6 4.Qh5+ Kf5 5.g6+ Black is mated; and after 2.&Kg6 3.h5+ Kh6 4.Nxf7 wins the queen.The main participants here are the bishop, which attacks h7 from its postat d3, the queen on d1 which uses the diagonal to transfer to the h-file, andthe knight on f3 which leaps to g5 with check.One of the most importantparts of the combination is the White pawn at e5.Since the Black bishopat e7 guards the g5-square, the combination only succeeds because of thepawn at h4 backed up by the rook at h1.Let s consider another example.Romanovsky-Belov, USSR 1929162. 1.e4 Nf6 2.Nc3 d5 3.e5 Nfd7 4.d4 c5 5.dxc5 e6 6.Nf3 Bxc5 7.Bd3Nc6 8.Bf4 Qb6?An error, since Black s development is not sufficient to allow suchexcursions.9.0-0 Qxb2 10.Nb5! 0-0 11.Rb1 Qxa2Diagram 157Now a typical combination follows:12.Bxh7+ Kxh713.Ng5+ Kg613.& Kg8 leads to a quick mate.14.Qd3+ f515.Qg3163.

Diagram 159Negra Kreculescu, Bucharest 1957White to moveNow that the knight on f6 has been exchanged, White unleashes thethematic combination:1.Bxh7+!! Kxh72.Ne5! Black resignsThere is a little twist here.The knight headed to e5, instead of g5.But themain idea is the same the clearing of paths for the heavy artillery.165. Diagram 160Lilienthal Najdorf, Stockholm 1952White to moveEven brief analysis of this position shows us why the Bxh7+ sacrifice islikely to succeed:1.The unfortunate placement of the Black forces, where they cannotcome to the king s defense.2.The possibility to bring White s rooks quickly into the attack.3.The Black king cannot find shelter on the opposite side of theboard.4.White s pieces are better coordinated.It is true that Black alreadyhas two minor pieces for the rook, but this is hardly an asset whenthe pieces are so poorly stationed.Such evaluations are important when investigating the secrets of tacticalplay that are hidden in such positions.Keep in mind that the value ofpieces is a relative matter, and that at any given moment an active rookmay be superior to two passive minor pieces.Sometimes, it is evenstronger than three minor pieces!166. 1.Bxh7+!This sacrifice destroys the remaining elements of the Black king sprotection and allows White to bring additional forces to deliver theterminal blow.1 [ Pobierz całość w formacie PDF ]
