When fighting dominant hand in front or weak hand in front?

Question

When you are defending your face

Answer 1

The usual way is fighting with weak hand in front so that you have more power on your dominant hand to cross over your shoulder. However, some boxer prefer their dominant hand in front, example would be Oscar De La Hoya who is naturally a left handed fighter but stands like a right hander with his dominant hand in front. When defending your face, you usually use your dominate hand to catch punches, just like mayweather uses his right hand like a catching a ball with a mit.
