2. Moving out of range - Side stepping or Taking a step back .
4. Last,I dont know if most of u agree w/ me on this ? Blocking the kick.
I agree with a lot of what you suggested in the above post, however...
Side stepping is fine, but since karate-types tend to follow a kick with a punch you'll just offer then a nice inviting target for that follow-up if you only step back...
As for blocking, nope. Not - in my opinion at least - Aikido, since you're opposing your strength against his. Obviously there are strong arguments to use your tegatana to maintain maai, but not to actually stop the kick itself..
Just 2p worth...
