Re: Boxing type punches
We do this once in a while. Usually we start up with a block or two, like boxers would do. The point is, that you probably often don't have enough time in such an encounter. So the first goal would be to survive the first one or two punches.
Basically we move into the back and take his balance by his shoulders (sorry, don't remember what the technique's called, my english isn't good enough to explain it better).
Anywas, the most important advice I've heard so far was : "Don't box with a boxer, do force him to do Aikido".
