Updated, changing some pieces names.
I would appretiate opinions about the rules for victory: Adding the
'capture both Travelers or reach the last rank with the remaining
Travelers' rule, the game is clearly a Chess variant, but I´m afraid it
would be more complex. Nevertheless, I can try some tests. It would be
also good a Preset in Courier (for tests, out of 'rating statistics',
please, or it is not going to be useful enough for the purposes).
