Mitsu-no-Sen Kumite - Forestalling
Senzen-no-sen - advanced one step kumite techniques used for reaction training. Attacking once your opponent has started (but not completed) their attack, look for a weakness or opening in the opponent to thwart his action, i.e. if the opponent is stepping in for a lunge punch, move in at the same time but quicker for a counter attack with say a reverse punch without blocking, if your distance and timing are good then, even if your opponent makes contact, his strike will have no power because he will not have had a chance to lock out his punch.
Go-no-sen - similar to above but emphasis is on pre-empting opponents attack. Allowing your opponent to attack first so as to open up target for counter-attacks or to respond to an attack with a counterattack or block/counterattack. However, the timing must be such as to strike immediately the opponent's attack is completed and before he is able to launch a further attack.
Sensen no sen - Attacking before your opponent attacks - a preemptive attack i.e. to attack when the opponent's intent to attack is perceived, thus preempting the opponent's attack and catching him off guard.
