I'm a longer guy and try to use the jab to keep my opponent out of his punching range in hands-only sparring. Sometimes this works and sometimes it doesn't, but I'm new and it's the only the thing I know to do. Once kicks are included in sparring, however, even this strategy goes out the window as I don't know how to maintain range against kicks, especially against guys who're faster than me. My jab isn't much of a deterrent in that situation since they have it beat range-wise with their kicks (which I know I need to get better at blocking/defending), and if I back up or otherwise move around to evade the kicks I run out of space quickly due to the small size of the gym. At the same time, I feel too slow with my own kicks, especially big ones, and am worried about exposing myself if I throw the wrong one at the wrong time. Can you guys suggest some strategies I might use to play to my advantage (length) and keep my opponent out? Maybe some kicks I could start working that work somewhat like a jab in terms of maintaining distance?
