Coordinates

The cells on the Hex board are referred to using coordinates of a letter and a number, e. g. a1 or c14. The letter usually gives the column, the a-column being at the left side of the board, and the number gives the row, row 1 being at the top side. A1 is an acute corner, having two adjacent cells. It is assumed that the first moving player is vertical, i. e. has to connect the rows 1 and n on an n x n board.
