I did not think that repetition would be an issue in pasgl312 chess.
If a position is the same except for the Train, it is a different position.
Therefore, in order to have a real rapetition. you have to wait for the
Train to come to the same place and have all the same pieces in the same
place, and have them all just as lunchvoll or lunchlos as they were before.
If the relative score is the same you can claim end of game and the higher
score wins. Is that a good enough rule?
This will not often happen, I think.
