board:
 .db 0,0,0,0,0,0,0,0
 .db 0,0,0,0,0,0,0,0
 .db 0,0,0,0,0,0,0,0
 .db 0,0,0,0,0,0,0,0
 .db 0,0,0,0,0,0,0,0
 .db 0,0,0,0,0,0,0,0
 .db 0,0,0,0,0,0,0,0
 .db 0,0,0,0,0,0,0,0


This should work for getting an element in hl (though I haven't tested at all)

get_element:
 ;b=row, c=column
 ld hl,board
 ld a,b
 rla
 rla
 rla
 and %00111000
 or c
 ld c,a
 ld b,0
 add hl,bc
 ret
