The letter "h" represents the file, which is the vertical column on the board, and the number represents the rank, which is the horizontal row. So "h6" would be the square in the 6th rank and the h file, while "h10" would be the square in the 10th rank and the h file. This notation is used to specify the location of a piece or a move on the chessboard. **
