Being an orthodox stance fighter, there is a "right cross" that counteracts an opponent left jab.
Does a "left cross" also exist for orthodox fighters? It would seem to counteract an opponent's right punch straight. I tested, and it works sometimes in sparring. However I never read about it.
*Only seen it for southpaw stance fighters obviously.
