Illegal screen or good offense

[gjacknow]

I have seen this:
To screen a moving opponent, the player must stop soon enough to permit his opponent to stop or change direction. The distance between the player screening and his opponent will depend upon the speed at which the players are moving.

If two opponents are moving in the same direction and path, the player who is behind is responsible for contact. The player in front may stop or slow his pace, but he may not move backward or sidewards into his opponent. The player in front may or may not have the ball. This situation assumes the two players have been moving in identically the same direction and path before contact.

But it still not obvious to me what rights the offensive player has when executing an offensive cut and not intentionally screening to get in the defenders way.
