Beat a defender by cutting sharply away at speed. Sell one direction, plant, chop the ball firmly across your body, stay low, and burst into the space, chopping with either foot to stay unpredictable.
From a start cone, dribble at a defender (a mannequin or cone) at speed. Just before you reach it, plant your standing foot beside the ball and chop it back across your body with the outside of the foot, then accelerate away into the space to a finish cone. Stay low, chop firmly, and go fast out of the move. Work both feet, and add a live defender once it is smooth.
Among the ways to change direction with a ball, the chop produces the sharpest angle available, close to ninety degrees and sometimes more. That is its value and also its price: cutting that hard scrubs off essentially all of your speed. A player who chops with a defender goal-side and no space to cut into has performed the move perfectly and gained nothing.
So the decision comes before the technique. The chop is for cutting into space that exists somewhere other than where you are running, which is why it belongs to wingers coming inside onto their stronger foot, or to a player forced towards the touchline who needs to get back into the pitch. Used as a general-purpose beat-your-man move it disappoints, because it trades speed for angle and speed is usually what beats people.
The technical detail that decides it is the standing foot. It has to plant beside the ball and take the body weight just before contact, because that is what allows the sharp pivot. Planted too far away, the player cuts the ball but keeps travelling in the original direction and ends up chasing it.
The other thing worth insisting on is chopping with both feet. A player who can only chop one way is entirely predictable in wide areas, where defenders already know which side they are trying to show you. Being able to cut either way is what makes the threat real.
Save it to your private drills, then change the animation, adjust positions, swap equipment, or drop it into a session block. Or start from a blank pitch and build your own.
