looks like all instances of this reverse move bug are when the player has 5 or less pieces.Fencer indicated in 2005( http://brainking.com/en/ReadBug?bgi=526 ) that it was when the player was down to one piece and it would be fixed HA ...check my game though,opponent had 3 pieces left Open Fast Espionage (grillyx vs. Celticjim)
Celticjim: In the game you referenced, it appears the rule held when your opponent had 3 remaining pieces. i.e. moves 56-57 the 5 from h1-i1 5 not moved next turn then with 2 remaining pieces moves 58-59 5 from i1-h1 then h1-i1 on the following move violating the rule. On another note, why did you not move the sab to j1 having already ID'd the bombs on a2 and b2, but instead allow your opponent to capture your sab?
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
Celticjim: I have received achievements too. The game reference link takes me to move 56. I didn't check previous moves until now for rule violations. Move 54-55: The 5 moves from h1-g1 then back from g1 to h1 next. Stranger still, other moves were available to the 5 as it was not trapped by its own bombs.
