What happens if a piece is blocking an approach and the enemy pieces vacate the opposite locale in the friendly player’s turn?
The printed rules are unclear on this point, and should be understood as follows: A piece may not move to block an approach unless the locale opposite that approach is enemy-occupied. Should the enemy pieces later leave the opposite locale, the blocking pieces must move into reserve – they cannot remain and continue to block the approach. Such blocking pieces may move into reserve in the same locale without it counting against the command limit, but if they move into the opposite locale, the move does count against the command limit. If the enemy pieces left in the enemy turn, the blocking pieces must leave in the next friendly turn; if the enemy pieces left in the friendly turn, then the blocking pieces must leave in that same friendly turn (NOTE: if the blocking pieces had already moved in that turn, they still must move out, but they must move back into reserve in the same locale; they cannot proceed into the opposite locale).
