@2, freakish amounts of backspin, plus he's pulling his punch, giving it just barely enough forward momentum to get over the net. His opponent will be expecting a rocket, not a dribble. And look how the balls bounce back. That's from the downward stroke of the paddle surface across the ball imparting backspin.
If I was playing this guy I would have no choice but to shoot him with a gun.
@5, I'm not so sure about "winning strategy". I think if you gave this guy a paddle and a bucket of balls, and me a Smith & Wesson, he'd still take two out of three.
