The dojang I belonged too in my early teens had two fighters who were truly ambidextrous, and it was one of the most infuriating things to me to face them. I got pretty good at fighting someone when I knew which hand (foot) they favored, but when they could switch at any moment......... SHEEESH!!!I was ambidextrous as a child, though I was forced to choose a hand and now write with my right. I train both sides equally, though I've noticed some differences in them. Kicks with my left leg are more accurate; my right is more powerful. In sparring, being able to fight with either side forward is often an advantage over one-sided fighters. When you're old and rickety (like me) it also helps to be able to switch sides to rest your legs.
But it made me have to grow too. That's why I'm a big believer in training both sides!
