Two unbeaten southpaws, one title, and a stylistic question that is rarer than it sounds: what happens when neither man has to adjust to a left-handed opponent?
The champion
Osleys Iglesias, a Cuban fighter based in Germany, is 15-0 with 14 knockouts, a finishing rate that makes him one of the most dangerous champions at super middleweight. He won the vacant IBF belt on April 9 by stopping Pavel Silyagin after eight rounds,
The challenger
Oliver Zaren is 19-0-1 with eight knockouts, which says more about his craft than his power. Trained by the Danish super middleweight great Mikkel Kessler, he is the IBF's number five contender. His last fight, against Jose Luis Navarro Jr. in Madrid on June 19, was ruled a technical draw after a thunderstorm ended it in the third round, so his last outing produced no full result.

What the style match-up says
Southpaw against southpaw is a mirror: lead feet line up on the outside, the jab meets the jab, and the straight left lands more freely than usual. It tends to produce a fight about timing and who owns the center of the ring, not who finds the better angle. Iglesias has the finishing record; Zaren has an unbeaten run built on fewer knockouts.
The lesson
Train against mirrors. Most gym partners are orthodox, so even left-handed fighters spend little time against other lefties. Ask a southpaw to spar you and notice how many of your usual habits (the lead-hand check, the pivot out) stop working. That is exactly what the champion and challenger will find on Thursday.
Mirror matches punish habit. Whoever has trained away from his own comfort zone will look calmer on Thursday.
