The basic step organizes weight and direction
In social dancing, the Cha-Cha-Cha basic step consists of two individual weight changes and a quick chasse. The commonly used count is 2, 3, 4 and 1. In a simple forward-and-back basic movement, one person steps forward on 2, shifts their weight back on 3, and then dances sideways. Their partner moves backward accordingly and follows the same rhythmic structure.
The key difference is between a foot that is placed and a foot that is weighted. If you only tap your foot when closing, you can't move the next foot freely. This often leads to an extra balancing step. So keep the chasse small enough that you can actually transfer your weight with each step. Keep your knees flexible; your hips don't need any separate action at first.
Figures mainly change direction, position, and connection. For a first short combination, the basic movement, a New Yorker learned in class, and a return to the basic movement are enough. The lead prepares the opening through body alignment, not with a jerk of the arm. You can choose either role. In a dance class for couples, you'll see how little hand pressure this takes.
