It is always written down, both to pieces and seek control of the center), the keep track of the number of moves and for “middle-game” (where strategy and tactics the analysis of the opening moves. The predominate), and the “end-game” (when term “ten-move game” is actually not quite many pieces have already been lost and the accurate as it may last a little longer or emphasis may shift to promoting a or shorter (see below).

However, over the years it has become 1. If, at the end of ten moves, one clear that with students rated under Level 6 player is clearly ahead by five points, or (USCF or Club-rating 600) a majority of more, he wins (with one half of the games are actually “lost” in the first ten normal rating value). moves, that is, during the “opening.” What 2.
