1)We cannot comment absolutely on hypothetical situations, as there are factors that come into play outside this forum. But Red is driving for contact with Blue & Blue is driving for the Blue so it would be generally Reds penalty. if any. Extension beyond 20" penalty would depend on who was judged to have caused the damage.

2) would depend on which side of the truss it occurred on of if red was in its goalie zone.

3)Might be better if blue went in the corner and his.

4)Pretty much covered by the rules.

As in all rules, the head referee would have the final decision for these kind of issues. Or any rules questions for that matter.
