Core Two Strike Combinations

There are far too many combinations to list them all. Here I've limited myself to listing one set of opposite side & one same side two strike combination initiated from the lead side and one set of opposite side and same side two strike combinations initiated from the rear side. (this likely comes across like word salad unless you have first read the section Combination Attacks). This list is primarily made to show you the possibilities. (I added a few more in for the kick variations since some of the kicks are mechanically very different from each other)

Elbow to Kick Combinations

Would only be used if your opponent quickly moves back to try and create distance from the elbow. 

III. Combinations Which Start With A Knee Attack 

Knee Combinations

I would never throw two unclinched knees in a row. After the first knee, I would clinch if I wanted to throw a second knee. 

Knee to Punch Combinations

L. Knee -> R. Elbow

R. Knee -> L. Elbow

Same Side

L. Knee-> L. Elbow

R. Knee -> R. Elbow

Knee to Kick

L. Knee-> R. Round Kick

R. Knee-> L. Round Kick

IV. Combinations Which Start With A Kick Attack

Kick to Kick Combinations

I originally started a far more extensive series on two strike counters which became too time consuming to work on. I may continue it at some point. Here is the link. 

Old  two strike combinations outline

Combination Attacks (Attack by Combination)

Combination attacks are sequences of two or more single attacks delivered in rapid succession, with each strike intended to hit its target. The purpose of attack by combination is to create openings by overwhelming the opponent’s defensive abilities and to maximize overall damage by increasing the likelihood that multiple strikes will land during the exchange.

Two Strike Combinations

One of the main challenges in learning attack by combination is the sheer number of possible strike sequences, which can quickly become overwhelming. To bring clarity and structure to this process, I begin the study of combination attacks by focusing on two-strike combinations. 

The four primary striking tools of the body used in combination attacks are the hand, elbow, knee and foot or shin (kick). When organizing two-strike combinations from these four tools there are 16 possible variations.  They are:

I. Combinations which start with a hand attack

    1) Hand to hand

    2) Hand to elbow

    3) Hand to knee

    4) Hand to kick

II. Combinations which start with a elbow attack

    1) Elbow to elbow

    2) Elbow to hand

    3) Elbow to knee

    4) Elbow to kick

III. Combinations which strt with a knee attack

    1) Knee to knee

    2) Knee to hand

    3) Knee to elbow

    4) Knee to kick

IV. Combinations which start with a kick attack

    1) Kick to kick

    2) Kick to hand

    3) Kick to elbow

    4) Kick to knee

By mentally focusing on this simple framework, students build a solid foundation from which they can build more complex combinaitons. 

Longer combinations are just the linking of two strike patterns, where the end of one is the beginning of another. For instance, a jab->cross->hook can be thought of as the two punch combos of jab->cross and cross->hook combined into a longer pattern. The key point is that once you get them down, your body knows how to perform longer combinations with ease. 

Opposite Side Striking & Same Side Strike

Two strike combinations can be broken into two primary categories: Opposite side attacks and same side attacks.

1. Opposite Side Attacks - Are simply two strikes delivered from opposite sides of the body. Examples would include: Jab followed by a Cross, or Lead front kick to rear knee. 

2. Same Side Attacks - These are two strikes delivered from the same side of the body. Examples include: Jab followed by a jab, or cross followed by a rear leg round kick. 

Opposite side attacks are the fundamental striking patterns in most striking arts as they generally are more fluid and more powerful than same side attacks. Since they are the standard pattern, an experienced opponent will generally expecte them and have certain defensive reactions ingrained. This is where same side attacks can capitalize on your opponents ingrained defensive reaction  (they expect the next punch to come from the other side) allowing you to land the second blow. 

With this in mind, I beleive if self defense is your primary goal opposite side striking should have far more emphasis than same side striking. The goal in a street confrontation is to end it quickly. The stopping power from opposite side striking provides this advantage. Additionally, your opponent in a street confrontation is less likely to have developed the defensive reactions of a trained fighter. This means the confusion that same side attacks may cause a trained fighter in a sporting event is lost on the street assailant. 

Initial Strike Side

All combination attacks, whether same side or opposite side, will be initiated from either the lead side or the rear side. 

Lines of Attack

Lines of attack describe the physical zones and directional planes through which strikes are delivered or defended—essentially defining where and how an attack travels. These are commonly broken down as high line, middle line, low line, inside line, outside line, straight line and curved line. 

High, middle & low refer to the three different verticle target zones. The high line is the area above the solar plexis to the top of the head. The middle line is the area from the solar plexus to just above the groin. The lower line is from the groin to the ground. 

Outside & Inside refer to the path of your attack as it relates to your opponents guard. I refer to anthing outside of your opponents guard as outside and anything between your opponents guard as inside. Alternatively, I might simply "side" or "front" and essentially be referring to the same thing. 

Straight and curved lines refer the atcual path of your strike from start to end. Regarding punches, the jab and cross are straight line attacks. The hook, uppercut and overhand are curved lines. 

For example, say you attack with a jab ->low rear round kick. The jab is is attacking the opponent high, inside, with a straight line strike. The low rear round kick is attacking the opponent low, outside, with a curved line attack. 

The most often referenced and useful of these terms is the high, middle, and low.

I think it's a good idea to have an understanding of these sort of theoretical breakdowns but don't spend too much time being concerened with perfect definitions and analysing things in an overly theoretical way. 

Putting It All Together

Applying these three concepts provides a wide range of possible two strike combinations. For instance, lets choose hand->hand. A same side attack initiated from the lead side would include jab->jab or jab->lead hook. Opposite side options initiated from the lead side would include jab->cross or jab->rear uppercut. From there we could create further variations by considering the high, middle & low lines such as jab (body)->jab (head). I could go on but I think you get the idea.
