Basically on top you can't lock hands to maintain control (unless in a pinning position) and you can't perform a headlock without another body part.

7-1. LOCKED HANDS PENALTY - A wrestler in the neutral position or defensive
position can lock hands around the torso or both legs of the opponent. But it is a
penalty for the offensive wrestler to lock hands (except cradles) around the torso or both
legs of the defensive wrestler unless the opponent is standing on their feet or within a
near fall count. Overlapping fingers is considered locked hands by the referee.

7-2. LOCKED HANDS AROUND THE HEAD PENALTY - It is a penalty from any of the
three scoring positions to lock hands around the opponent’s head without an arm or leg
included. You must also allow your opponent to breathe in a headlock or the referee
can stop it as potentially dangerous.
