Luthien
Smash Ace
Yeah, sometimes I'd rather shoot them too. Basically, AllanT, I'm telling you how to get your friend in the right mindset. I'm just trying to help you keep your friend from abandoning smash altogether; my friend was very close to it. But eventually, he grew up because he was inclined to, not because everyone was telling him that he was wrong and such. He'll be far more willing to listen to you/Sirlin after he's realised that Smash can be fun AND a challenge.O.o Surprised I am by Luthien. +1 for you.
My advice is the same as Luthien's really. The only reason I would think AllanT want's to play him is so he can find someone who is also "dedicated" to smash, and thus he can have fun playing his best vs his friends best.
The only other reason you could possibly want to play him is just to have someone to play with (I've been playing comps for 3 months now, I know what that feels like >_>) but that would be a self-defeating reason.
Why? Because, a person who is willing to play smash and is "dedicated" (aka mature, aka non-scrub mindset) will play smash with you seriously.
A person who is willing to play smash but says "anything you do that wins is cheap" is only there to destroy you. His only purpose is to make you satisfy him. He wants to win, because in his mind he is entitled to it. Because of this insanity, I don't have a clue as to why you would even want to play with him, let alone bend over backwards to have him waste your time.
That's why I suggest Sirlin's site. Who cares if that gives him the idea that you think he is a scrub. Truth is truth. If you think the statement "Truth hurts" is applicable to your life in anyway, quit living a lie.
The only possible reason you could have to go easy on him is if he genuinely wants to learn how to play and thus you show him the ropes, so to speak. Go over theory with him, go over game mechanics, go over everything. Make him question, watch videos, learn, put effort in, etc.
A huge pointer is Isai's famous saying: "Don't get hit." A very simple and powerful tool that would help your friend immensely. Ask him why he's doing certain things. Watch him play against a computer, ask him why he did this, did that. Help him practice AT's. I learned to wavedash by myself with Link. Everytime I killed a computer, I would try to wavedash while they were respawning. Since you have two controllers, you can just make an empty game and go over it with him. None of the advanced tech's are hard, they just need patience and a desire to improve.
Though Luthien is probably correct on one thing though. Be gentle and such. I have a very abrupt method of dealing with people because I don't have the desire to mold people from immature to mature. I would rather shoot an immature scrub on sight than deal with them in any way.
Jazriel is telling you what to do after your friend is in the right mindset. Follow his advice after you've won your friend's respect (because he clearly doesn't respect you) back. Just make sure your friend is willing to do this with a positive attitude. That's about it.
Edit: YES! DO WHAT RED EXODUS IS DOING. Avoid gimping him the whole match (give him hope, because no one wants to play if they only lose), and turn up the heat later.
