Wang liqin had more than his dominant forehand. His safe backhand, his well placed serves, his great footwork and physics. He is so powerful that there was no place for creative play, more important has been a constant pressure on the opponent.
his footwork and forehand, amazing. only off balance a little bit when in deep backhand but for his height. pretty darn amazing. i would say ryu seung min in his prime would slightly be more favorable fore hand vs fh.
