UNDERSTANDING - DELETING THE ANTINAUSE STITCHES WITH THE LINE | SCHECHENING COMBINATIONS
Removing the checkers from the mating lines - BREAKING Along with the lattice arrangement of the checkers, an important characteristic of the combination position is also the absence of pieces on the dam line. The basis for the search for a combination is the absence on the line of the checkers - this immediately indicates the possible direction of the combination strike. Therefore, in responsible tournament games, both players are usually reluctant to shift the checkers from their first contours, either by extreme necessity or when they are confident that they are not threatened by a combination. In this regard, a special type of combination appeared, based on the removal of the opponent's checkers from the dam line before the final strike. Such combinations are most often encountered in the following position of the checkers: white - h6, black - f8 and g7 (when the combination is white). In this case, the checker f8 has to be removed. The last move of the black players was f6-e5. The Blacks presumably believed that after White had entered the field L6, the turn of the turn would be behind the Blacks, and therefore it was too early for them to be afraid of any combination of the enemy. Moreover, the calculation shows that, in spite of the lattice position of the e5 and e7 checkers and the absence of a checker on the d8 field, a combination in this direction is hardly possible. But White reasoned otherwise: they can fall on the field L6 in two ways: either just play 1. g5-h6, or make a change: 1. g5-f6 e7: g5 2. e3-d4 c5: e3 3 .d2: h6. In the second case, simultaneously with the hit of the white checker on L6, the black simple c5 and e7 are removed and the required combination of pieces is created: L6 (white), g7 and f8 (black). Immediately the idea arises: is it possible to put a black checker on L4 and to strike a3: e7 by removing the black piece from the field f8? Thus, the exact order of the moves of this combination arises:
