The ability to take dinks out of the air before they bounce — intercepting them as volleys. This steals time from opponents and creates attacking opportunities they can't see coming. The key enabler is body height: you must be low enough to see and reach these opportunities.
Get into your lowest comfortable volley posture at the kitchen line. From this low position, you can see balls that are still above net height and take them out of the air. Standing tall means these same balls appear below net height from your perspective and the opportunity is invisible until the ball has already bounced past the kitchen line. After pulling an opponent off the court with a well-crafted dink, immediately transition to low posture to intercept the response as a volley into the open court.
When standing tall at the kitchen, balls that are actually above net height appear to be below it from your eye line. You literally cannot see volley dink opportunities because your perspective makes them invisible — by the time the ball drops to where it looks playable, it's already bounced past the kitchen line. Getting low changes what you can physically perceive, not just what you can reach.
Ben Johns: "Default is out of the air. Adjust if I can't." Most players default to letting balls bounce and only volley when it's obviously easy. Ben's default is REVERSED — he tries to take EVERYTHING out of the air and only lets it bounce when he physically can't reach it. "I want to see you reaching in and sometimes realizing you can't — that's a GREAT thing, because you're learning your envelope." This default-state reversal steals time from opponents on every single ball. It's not a technique — it's a decision architecture.
Navratil: the reason pros look like they have all the time in the world to dink is the DROP STEP. Volley-first mentality: you stand at the kitchen to take balls out of the air PRIMARILY. When you realize you can't reach it as a volley, push off the front leg and drop the back leg back. This keeps the ball in front of you (not reaching behind or half-volleying). Weight still loads forward even as the leg goes back — you push back toward the kitchen from this position.
