Hi Guetti :)

Well, when you use the short algebraic notation to print out moves, (eg Nxe5)
you probably have to reply the moves on a separate copy of the board anyway.
Otherwise you also don't know whether it should be 'Nfxe5' (because a 2nd knight
could also capture on e5) or not. And if you replay the moves on a separate copy
of the board, you can do the checktest there too.
