It is best not to think of Capoeira as a fight when practicing movements, otherwise you will be too rigid. Capoeira movements should flow from one to the next, as in a dance. The Capoeira fight is epitomized by unpredictability, and technique.
Ginga is the base of all movement, in a sense all moves flow from it and into it. Generally a Capoeirista does not block an attack, they flow with it and counter with an attack of their own.
