If the stronger side is to move in a "cyclic zugzwang" position, it wins more slowly than with the other side to move, and in order to win, the stronger side can be forced to visit the same position but with the other side to move. The key position for this study was discovered by John Bryant (see  https://www.youtube.com/watch?v=2h_b0puS8Vk ). I conjectured that this position is a genuine cyclic zugzwang (not only the shortest path but all paths to win must go through the BTM position) and that later was proved to be true by some specially modified Freezer and FinalGen softwares.} 1-0
