I gave a rule for stalemate even though I was not sure it could happen in
pasgl312 chess.
You may question my consistency. Repetition is clearly possible, althogh it
is difficult, and I thought of it bur chose not to mention it at all.
The difference is that for this game there is one clear and simple rule for
stalemate. I could write down the rule and be sure that it was correct,
even though I could not be sure that the situation it covered was
possible.
Instead of keeping silence, I chose to write down the one true stalemate
rule because I felt that it expressed a truth about the game that would
help you understand the game.
You could almost add it to rule zero: 'for point-scoring games, stalemate
is a non-event.'
