The first case doesn't count as two dribbles! This is against the rules! You can shake your opponent with your right foot! But your left foot can't leave the ground! If you step back, clap your hands and clap your left foot backwards!

The second case is the same as the first case! You don't hit the ball, you take three steps! Must have left! You can leave the ground with your left foot on the racket! That's it! Generally, this kind of ball moves together. Even in the NBA, it is difficult for the referee to judge whether you are walking or not! But in the second case, you must walk!
