Dark Prince: I think you need to recheck the move numbers there mate.There was an occasion AFTER the rule break where his 5 did stay unmoved in the corner next to his HQ

*edit* you are partially right,there was another rule break when he had 2 pieces left that I didn't even notice.Go back further tho to when he had 3 pieces

as to why I let him take my sab
I was finished with it.I wanted to capture all the mines to get that achievement which I did.3 more to get the MASTER achievement that only aaru has so far---yeah a bit geeky but ya know I love the game
