The bottleneck is a strategic formation in the game of Hex where one player blocks the opponent's progress by occupying key positions on the board, creating a narrow passage that is difficult for the opponent to break through. The board fragment shown below illustrates this concept, with Blue occupying the key positions in a bottleneck formation, hindering Red's ability to connect to the bottom of the board.

This formation often leads to a ladder, with Red getting ladders in both directions, as shown in the second board fragment.
