BLITZ TOURNAMENT

Is it possible to load a game for two players and then make a move for your ally?
There are ways to counter this tactic. Only inattentive hosts would allow it.

When generating a starting save (in the map editor), the "Human Player" option is usually disabled for all heroes except the starting one... So, you can only make a move for your ally on random maps... In any case, this is a normal rule for normal tournaments. Or does Iron know some trick?
