Whats the difference between 3 step, 2 step and 1 step?
Some general comments on how we do step sparring, first
- unlike free sparring, there are
no illegal techniques in step sparring
- appropriate to the rank and abilities of the students, step sparring may include grabs, throws, and controls, although the focus of the sets should be on striking techniques (kicks and punches)
- all sets alternate - that is, if person A attacks and person B defends, then in the next sequence, person B attacks and person A defends, unless otherwise specified (e.g. if person A is testing and person B is not, then person B may be attacking only, especially in 2 step and beyond)
3 step involves repeating the same attack and block 3 times in sequence - basic 3-step is
very codified, with the attacker performing 3 middle punches and the defender performing 3 middle inner forearm blocks (there's more, but that will get the idea), with both in walking (front) stance, then the defender counter-attacks with a reverse (rear hand) punch, and is learned by white belts. Once they have that format down, it is expanded to any other technique and stance the student knows, but still with the attacker performing the same technique 3 times and the defender performing the same block 3 times, and then one counter-attack. Generally speaking, all attacks are with the hands, although counter-attacks often include kicks. The focus of 3 step is distancing and timing.
2 step involves 2 different attacks by the attacker, and 2 different blocks by the defender. 2 step sparring in introduced at green belt (6th gup). The defender tells the attacker what attacks to use, including stance, height, and tool, and then blocks accordingly; after the second block, the defender counter-attacks. The number of counter-attacks varies depending on the rank of the defender and the difficulty of the techniques, but is usually no more than 3. The focus of 2 step is knowing the names of all of the techniques (so you can tell your partner what to do), understanding their applications, and knowing how to block them. Distancing and time is moved to the next level because the attacks are different, instead of the same as they are in 3 step.
1 step sparring involves 1 attack by the attacker, and 1 block by the defender, who then counter-attacks. 1 step sparring is introduced at high blue belt (3rd gup). The focus of 1 step is single-strike techniques - ending an altercation with a single strike, possibly 2 (depends on the technique).
Model sparring is 1 step performed at 2 speeds - the first is full-speed; the second repeats the same set at 1/2 speed or slower, to demonstrate technical proficiency.
Pre-arranged sparring is a set of 8-12 sets (one set being person A attack, person B blocks, person B attacks, person A blocks) that is predetermined by the participants. Pre-arranged sparring is introduced at red belt (2nd gup).
Semi-free sparring is an alternating set of either 2 or 3 attacks and blocks (one set being person A attack, person B blocks, person B attacks, person A blocks); however, it is
not predetermined. At the end of the 2nd or 3rd set (depending on what the instructor calls for) the last attack is not countered, and is considered a "win". The only caveat is that whatever type of attack person A begins with (e.g. hand, foot, jumping, etc.) person B must use the same type of attack, and the sets must alternate between hand and foot attacks. Semi-free sparring is introduced at 1st Dan.
All of these drills were originally intended to lead up to free sparring at black belt, by which time they would have provided the participants with enough experience to be able to free spar without killing each other. In practice, however, free sparring begins at white belt; there are very few people who start MA and would be willing to wait 3-4 years minimum to learn to spar, especially those who start for the purpose of learn self-defense.
