We need pictures up next time. This is harder to explain than I thought.
I checked it out last night. There are two types of slips. One is duck-down and to the side, which I was refering to. The one that Ayub was talking about was the backward sway slip [Twist your torso, like said in Wikipedia].
Now Ayub wrote twisting the body and moving the head, so I thought he meant bobbing.
Now Ayub. Slipping is a very complicated matter in Kickboxing matches. If you slip to the outside, it's fairly safe, but if you slip to the inside [which some people prefer], it is possible to get hit by the knee. Also, in MT matches people don't put much force in their hands like boxers do as they have other weapons they can use like their feet. Thus it is really rare to see someone who tries to lunge a straight with full force, and the slip wouldn't successful. MT boxers don't commit their hands in short.
MT boxers uses the jab to gauge distance, so it is quite difficult to slip a far-away jab. Another thing, you slip to the outside, there's the risk of the elbow. Many have been caught with the re-tracting elbow from the a slipped jab.
But in all, it is ok to use slip in MT matches but much of the fighting is not high, it's more centered around the middle section of your body. Thus, when you see 2 MT boxers punching away, you will notice they are hitting the chest area rather than the face as boxers have the habit of covering their faces with the huge gloves.
Another reason. It is hard to slip when the opponent thinks of clinching as soon as you get near. So most of the fighting is long-range or clinch. Not many people fight "inside" like Kickboxers and boxers do.
But still, Ayub you have proven a point. If occassion occurs, it is possible to use a slip but there are more risks involved when you have the ability to fully use your whole body.
