[Aleks Peshkov]

The reason a lot of people use A8-0 is that it maps transparently to FEN and EPD (where the first square is A8).
A1=0 is also quite natural, if you imagine playing as white.

A8 = 0 is more natural to represent a board as C-array of constants.

Code: Select all

enum square_t {
    A8, B8, C8, D8, E8, F8, G8, H8,
    A7, B7, C7, D7, E7, F7, G7, H7,        
    A6, B6, C6, D6, E6, F6, G6, H6,        
    A5, B5, C5, D5, E5, F5, G5, H5,        
    A4, B4, C4, D4, E4, F4, G4, H4,        
    A3, B3, C3, D3, E3, F3, G3, H3,        
    A2, B2, C2, D2, E2, F2, G2, H2,        
    A1, B1, C1, D1, E1, F1, G1, H1
};

The "I am playing white" mapping is no more complicated:

Code: Select all

enum square_t { 
    A1, B1, C1, D1, E1, F1, G1, H1 
    A2, B2, C2, D2, E2, F2, G2, H2,        
    A3, B3, C3, D3, E3, F3, G3, H3,        
    A4, B4, C4, D4, E4, F4, G4, H4,        
    A5, B5, C5, D5, E5, F5, G5, H5,        
    A6, B6, C6, D6, E6, F6, G6, H6,        
    A7, B7, C7, D7, E7, F7, G7, H7,        
    A8, B8, C8, D8, E8, F8, G8, H8, 
};

Yes, I definitely vote for this one. It looks like stolen from my header file ...
