yup there is a russian hook? or perhaps an uppercut off the right hand that actually is a snaping punch that is thrown to the chin and sets up a nice straight right...thrown like a martial arts backfist but loops up from under the fighters guard as you throw it step out and throw a right can be useful at putting the chin up and into the path of ther right. it doesn't have a lot of power, but it scores and shakes up guys that ain't expecting it i use it a lot with the philly shell defense and when used like the rjj jab or after jabbibf from the waist it is easy to throw the opponent off. also check out the cuban uppercut... nasty tech good for mma fighters esp.
