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?
