to give you more of an idea what i mean...
If you are serious about a long range kicking game, as a tactic, you have to be balls out, obviously you want to finish the fight and not mess around for a long time, and if your space is limited you dont have the luxury of timing this and that so you dont get blocked, you will have to be aggressive and fearless.
If you cant do that then they WILL break your range. a good long range game with kicking requires intense levels of aggression. Forcing someone else to block or defend creates time for you, in long range you need that time in order to maintain range.
You may well have seen Buakaw before but ill link you a clip, this thai boxer is a long range kicker, this is the ring however, but it shows you how aggressive you have to be in order to maintain range and that issues of them blocking cant affect your fighting, you just have to kick anyway, in this way, if you can get your mind round to this, you can be successful with this strategy. the smaller the space you are in the more aggressive you will need to be in order to maintain that range.
Have a watch, the first min is promo nonsense but then you will see what i mean a bit.
