Generally speaking, is a left of much value in Muay Thai?
I have, on a very few occasions, sparred under "International" Muay Thai rules (i.e. no elbows) and have not really been able to use, nor been hit by anyone else's, left hook because it seems that once we get into a close enough range to launch an effective hook, it is rather easy and tempting to lock up a clinch. Does this mean that if one were to cross over to Muay Thai that it would be best to concentrate on futher refining their jab and straight right as opposed to their left hook? Or does one see, generally speaking, just as many left hooks thrown in Muay Thai as straight punches?
