User:Amos is Ward/Orthodox stance

Lead
In combat sports such as boxing and MMA, an orthodox stance is one in which the fighter places their left foot in front of the right foot, thus having their left side closer to the opponent. Because it places the right side, which is the stronger side for most people (see laterality), in the rear, the orthodox stance can generate more power with punches and kicks by further exploiting the already stronger right side, allowing for more rotation and distance to accelerate right sided strikes. This is why it is the most common stance in boxing, as well as MMA, and primarily used by right-handed fighters.

Usage
As mentioned above, orthodox stance is the most common stance in boxing and MMA, owing to its superior power generation for right-handed individuals, who are the majority of the population. The stance also finds usage from some left-handed individuals however, owing to some of the advantages it has in general, as well as for lefthanded individuals in particular. (See examples of such fighters below)

Advantages (in General)
The orthodox stance has two major advantages for all practitioners, it's commonality and placing of the lead hand and foot closer to the right side of the opponent. Regarding commonality, since it is the most common stance, high quality training in the stance is more available. Furthermore, most of the opponents any fighter trains with will be orthodox, building greater familiarity with the stance. Additionally, because the left side is forward, the left and right foot are quite close to the opponent's right side. This is particularly useful as the liver is a very vulnerable target to strike at, various fighter such as Bas Rutten and Stipe Miocic have KO'd other fighters through liver shots. This proximity allows for quick shots which can sneak past opponent's defenses, as demonstrated by the aforementioned two fighters.

Advantages (for right-handers)
As mentioned, placing the right hand in the rear allows for the most powerful punches from right-handed individuals, since the right, more powerful, side is in the rear, there is more time and rotation of the body between launching the punch and impact, allowing for more power generation.

Advantages (for left-handers)
For left-handed individuals, the orthodox stance provides the benefit of placing the more powerful hand in the front. This provides more power to the quicker punches of the lead hand, such as the jab and lead hook.

MMA Considerations
The same power advantages of punches described above also apply to kicks for the respective dominant sides. Further, for right-side dominant fighters, having the stronger foot in the rear allows for more stability when defending takedown attempts.

Statistical Advantage
Statistically, orthodox fighters are not more likely than other fighters to win, but regardless of their stance, fighters are more likely to beat orthodox opponents.

Prominent Examples of Orthodox Fighters(right-handed)
Since the orthodox stance is so common, especially as pertains to right-handed individuals, there is a quite extensive list of prominent right-handed orthodox fighters such as Muhammad Ali, Floyd Mayweather, Sugar Ray Robinson, Khabib Nurmagomedov, and Jon Jones.

Prominent Examples of Orthodox Fighters(left-handed)
While this stance is predominantly associated with right-handed fighters, there is a notable contingent of left-handed orthodox fighters, including some very prominent figures such as Oscar De La Hoya, Sonny Liston, Miguel Angel Cotto, Gerry Cooney, Mike Tyson, Sean Strickland, Michael Bisping, Renan Barao, and Marco Antonio Barrera.

Alternative stances
The opposite stance to orthodox is southpaw, in that it is a mirror image of the orthodox stance. A southpaw fighter stands with their right foot forward and thus their left side further from opponent. Some famous boxers who use southpaw are Marvelous Marvin Hagler, Victor Ortiz, Sultan Ibragimov, Naseem Hamed, Joe Calzaghe, Manny Pacquiao, and Lucian Bute. Famous MMA southpaws include Nick and Nate Diaz, Conor McGregor and Anderson Silva.

Notably, many fighters such as Francisco Palacios, Andre Ward, Jon Jones, and Terence Crawford normally fight as orthodox, but occasionally switch to a southpaw stance. Hagler was the opposite, normally fighting southpaw but sometimes switching to orthodox.

While southpaw is generally associated with left-handed fighters, there are some right-handed individuals who favor the stance over orthodox, such as Vasiliy Lomachenko, Shakur Stevenson, and Nate Diaz.
