121 /* [HGM] Some notes about board sizes:
122 In games that allow piece drops, the holdings are considered part of the
123 board, in the leftmost and rightmost two files. This way they are
124 automatically part of the game-history states, and enjoy all display
125 functions (including drag-drop and click-click moves to the regular part
126 of the board). The drawback of this is that the internal numbering of
127 files starts at 2 for the a-file if holdings are displayed. To ensure
128 consistency, this shifted numbering system is used _everywhere_ in the
129 code, and conversion to the 'normal' system only takes place when the
130 file number is converted to or from ASCII (by redefining the character
131 constant 'a'). This works because Winboard only communicates with the
132 outside world in ASCII. In a similar way, the different rank numbering
133 systems (starting at rank 0 or 1) are implemented by redefining '1'.
