Re: Guys Who Tend to Circle to Their Left (Your Right)
Most orthodox fighters move that way, to their left, and a suprising number can only move that way (and punch). It sounds like he is either drawing your punch and stepping around it, or you are telegraphing it, allowing him to avoid your right hand. You want to time your right hand so he is moving into it.
Slide your lead foot close to his-this will change the angle, when he circles he'll still be within your range, if I'm making sense. Also, when you go to your right, start by sliding your left foot to the right (right into his lead foot, in fact), then pivot on it. This gives you better position to land your right hand.
I hope that makes sense? I could show you very easily, but I don't think I am explaining it too well.
