If you play mixed, you need to know this.
The best women in MXD use it constantly, and the best men know exactly how to respond.
Once your opponent puts their head down, that's your window to attack. And when you're the one being attacked? Protect your line and trust your partner to handle the middle.
Mixed doubles works best when both players understand their responsibilities.
Takeaway: Attack when heads drop. Defend your lane and trust the system.
