What is the critical distinction between Ippon Kumite and Sanbon Kumite regarding the development of tactical awareness?

The critical distinction between Ippon Kumite and Sanbon Kumite regarding the development of tactical awareness is that Ippon Kumite primarily focuses on developing immediate, decisive responses to a single attack, while Sanbon Kumite emphasizes adapting to a sequence of attacks, building anticipation, and recognizing patterns. In Ippon Kumite, or one-step sparring, the defender knows the specific attack that is coming and can pre-plan the proper defense and counter-attack. It is very precise in the movement, however, it doesn't allow the defender to learn about changing movements of an opponent. Sanbon Kumite, or three-step sparring, the attacker performs a pre-determined sequence of three attacks. The defender must block each attack and then counter. This allows the defender to develop a tactical awareness of the sequence of incoming strikes and determine the counter to deploy. An example is blocking an attack, but knowing two more will come. Sanbon Kumite begins to develop tactical awareness of multiple attacks, while Ippon Kumite is purely defensive.
