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