Years ago I was in a Capoeira class and training with a young lad I had not seen before and I assumed he was a new student. We were doing a simple practice session of ginga when all of a sudden he threw a roundhouse kick at me. Random surprises like this are a bit of a tradition in Capoeira but you do not really expect them from a newbie. Turned out this guy had taken a few classes at another location.
When he tried another kick I was ready. I stepped away and let my trailing leg nudge his support leg, just enough to wobble him and let him know I could have dropped him hard if I had wanted. The look on his face was priceless.
“You just avoided the kick and hit me with the same move!”
The move I used was a variety of Esquiva  and here is an illustration of one of its applications.
