Open hand only since women do not really ever require a closed fist to humble and you don't want to cause permanent harm unless you're a monster or she is trying to seriously injure you. If it's your wife or girlfriend, it should be permissible to slap them under certain socially deleterious circumstances that can degrade families and communities like if she cheats, spreads serious allegations as gossip, isn't tending to the children (e.g., feeding them goyslop instead of home-cooked meals constantly despite your protesting), and others.
