lol, never thought of that, they must of had some method, cause they played
it at a club for 50 yrs.
maybe there was a lot of arguements ... 'hey yu can't move that pawn
there, that is illegal' .. 'no it's not, it's going that way' .. 'no
it isn't!' .. 'yes it is, i got it to the end and it's now going back'
.. 'no you didn't you cheat' ha ha :)
