Each Opening Creating Another

The difference between an expert and a novice fighter is that the expert makes use of each opportunity and follows up on each opening.  He makes use of his sensitive and dominating aura and his imposing rhythm.  He delivers his blows and/or kicks in a well-planned series, each opening creating another, until finally a clean shot is obtained.
