The pictures below show a sequence of techniques
done in close distance. Student A moves very slowly and stops of course before hitting B.

B (on the right) attacks A with a punch. A blocks and counters with kneeing. This technique has not the expected effect, so A can´t get off yet.

Student A punches twice going two steps forward. B goes two steps back.

Student A aimes a kick in the groin, puts her foot on the floor again and runs away.
