Wrong… sorry
i agree, maximus, you seem to have missed something…
anyway i think i can put in a bit more input in here…
i thought about this a while ago when sparring with a friend of mine who does longfist. we went on holiday together and spent and hour or two sparring on the beach everyday for about 2 weeks. which is a northern style, and consists of large movements and longrange attacks.we went on holiday together and spent and hour or two sparring on the beach everyday for about 2 weeks, so i had ample time to think about it and develop my technique to suite his style, as he did to mine.
i thought i (doing wing chun) would kick his ass completely, as long as i could get in close. this however wasnt the case. the reason being if i ever managed to get in close (he has been training quite a bit longer than me and is pretty much better than i am) he would either:
-push me backwards, way out of range.
-use infighting like elbows, uppercuts throws or takedowns
-step back.
so it ended up that it wasnt that simple. anyways my point is that in the case of long range fighting…which is his preffered range, he would completely destroy me. if i did manage to get in close, i would do much better at MY range, and actually land a good couple of centerline strikes.
usually however he would be able to cope more or less pretty well at close range though.
the point is this (sorry about the rambling) is that in wing chun, the best distance for a practitioner to be in is close range, (ie trapping punching elbows throws takedowns knees and very low kicks) in longfist, the prefferd range is long, (high or low kicks and punching using low forwards leaning stances eg bow and arrow stance.)
BUT… this is not to say that wing chun cannot fight at long range. i definately can, using kicks. i have less techniques at long range, but i do have some,the key to wing chun long range fighting is to bridge the gap, as in chum kui. there are many techniques to bridge the gap in wing chun and thus close in on the opponent and get into the best range for oneself. Long fist has the opposite, a large amount of long range techniques, with the emphasis on keeping that range, if the opponent closes the gap, the longfist fighter will have a couple of techniques to fight in close range, but the majority of them will be aimed at pushing or throwing or somethinging the opponent back to long range…
see what i mean i hope… btw this is all mho
