Intensive Course Tactics - Part 1

Intensive Course Tactics George Renko "Intensive course tactics" is a CD featuring a new classification of elementary tactical methods developed by the author, allowing it to categorize the immense diversity of positions containing hidden opportunities of combinations. This offers a systematic method to sharpen your combinatorial vision and improve your technique - for any chess player, from novice to expert. The first thing to do when analyzing a chess position is to look for possible attacking squares squares with unprotected pieces, squares to threaten mate on etc. In the majority of cases, these different types of squares have one feature in common: the same number of defenders and attackers. In chess terminology they are commonly called critical squares. Each critical square features a temporary balance of attacking and defending forces. Completely unprotected squares could also be referred to as critical, meaning no attack and no defense whatsoever. In order to seize a critical square, it is necessary to weaken it. To this end you either have to increase the number of attackers or vice versa, eliminate defenders. This can be achieved by applying one or several elementary tactical methods. Example 1. Tchigorin - Yanovsky, Paris, 1900.

White to move. Black's position has two important critical squares: 1. f5 - attacked by the white knight g3 and protected by the black queen; 2. f8 - attacked by the white rook d8 and protected by the black king. White wins with the move 1. Qc5 attacking both critical squares once more.

Connecting several elementary tactical methods together is called a combination - similar to when atoms of various chemical elements join together and make a molecule. The multitude of elementary tactical methods can be split up into two large groups: direct hit methods and support methods. Under direct hit methods we understand tools leading to direct material or positional advantage (such as checkmate, double attack, discovered attack, skewering attack, etc). Support methods, in contrast, only prepare a situation on the chess board in which one of the direct methods can be applied. These tools - deflection, decoying, annihilation of defense, interception of the line etc. - decrease the number of defenders of an important critical square, which then can be seized applying one of direct hit methods.

Example 2. Tid - Delmar, 1896. White to move. The critical squares g6 and h5 are the squares of checkmate threat. One of them can be seized after decreasing the number of defenders by means of deflection: 1. Qxh5+ Rxh5 2. Bg6# There is a small but very important group of universal tactical methods. Depending on the situation, these can both be direct hit methods or support methods. The main tactical tool in this group is the pin.

Pin as a direct hit method. Example 3. Robatsch - Jansa, Sochi, 1974. Black to move. Black captured white knight: 1. ... Bxc3 and resigned after 2. Qd2! with the double pin.

Pin as a support method. Example 4. Source unknown. White to move. After the decoy 1. Rd8+! Kxd8 the black knight f6 is pinned and does not protect the queen anymore, so that 2. Qxe4 wins the black queen and the game. The database is structured to provide the best comprehension of material. Folders and files are numerated. The best way to use this database is to follow the proposed order. George Renko
