Southpaw vs orthodox

Orthodox is right foot back, right hand as the power hand. Southpaw is the mirror image. When two fighters share a stance, their lead feet are opposite each other and every punch they have thrown in training lands the way they expect. When the stances are mismatched, their lead feet are on the same side, and almost nothing lands the way either of them is used to.

In a mismatched stance, whoever gets their lead foot outside the opponent's lead foot has an open angle to the body and the chin, and the opponent's power hand is pointing at empty air. Watch the feet for the first thirty seconds and you will usually see one fighter quietly winning that battle over and over. The one losing it keeps having to reset.

• Who wins the lead-foot position in the first round.
• Whether either fighter switches stance to neutralize the mismatch — and whether they are balanced when they do.
• Rear leg kicks landing unanswered. In a mismatched stance those are nearly free, and a round of them shows up in round three.
• How many southpaws the orthodox fighter has faced. A career spent against one kind of opponent is a gap you can see coming.

The rear straight down the middle

With the lead hands on the same side, the pocket down the middle is open for both fighters. These fights are often decided by whoever lands this one first and more often.

The lead hook

The shot that comes around the outside of the shared lead hands. It arrives from a direction neither fighter sees much in training.

The rear leg kick

Each fighter's rear leg kick travels straight into the other's lead leg with nothing in the way. The cheapest damage available in these fights, and the most consistently underused.

Southpaws tend to have the advantage, but not because the stance is better — because of exposure. Most fighters are orthodox, so a southpaw has spent a career solving this puzzle and their opponent has not. That advantage shrinks fast against anyone who trains for it or who switches stance comfortably, and it is worth nothing at all against a wrestler who never lets the fight stay on the feet.

Stance is on the Fighter File already, so the thing worth writing down is the matchup history: who they have beaten and lost to in each stance. Adaptability is the tag that matters most here — a fighter who solves the mismatch by round two is a different problem from one who spends fifteen minutes reaching.
