Crushing Chaos

Hi everyone! I wanted to start a topic focused more around chaos and there weaknesses and strengths. my friend and i play a lot and he used to use space marines, but he got bored of them and want ed something more interesting, and to him, chaos really appealed to him. we used to just do troop/HQ skirmishes, and we didn't really pay much attention to points and stuff. but now we are collecting a lot more and were starting to actually get a mix of stuff in our games, so I was wondering, is there a good way anyone has found from experience, to beat a chaos army? 

Well i play Chaos Space Marines myself their weakness is nothing. What you need to do is deny what their so good at. Use reaver jetbikes or an awesome denial unit and wipe out their AT and AI. If the opponent brings oblits take them out even if it takes your entire army to do it. One thing chaos cannot do what SM can is drop pod assault us Chaos dont believe in drop pods. Use speed to your advantge why do you think i struggle against tau, eldar, dark eldar, necrons, dark angels, and etc.... Because we are not as manipulative and alpha striking speed as us DE. Hope that helps cheers

One things for sure don't and i really mean don't ( i play CSM i know what my army can do in the right hands ) let your opponent make you play his game, play your game and ignore is sense of manipulation remember your dark Eldar we laugh at inferior slow armies like chaos( even though were tough as bricks) use speed to your advantage, it has done me so good. The top priorty units need to be gone ASAP

Scoring units
Obliterators as they can wreck anything imagine 3 assault cannons to your precious transports (you dont want that)
Havocs
Heldrakes as they ignore cover
Sorcerers
Daemon princes espcially them because one prince alone destroyed 2 raiders and 3 venoms as i ignored him
Noise marines with blastmasters as once again they ignore cover
Any close combat unit capable of bring down raiders or venoms

Ignore any tarpits as not many are that strong unless they are spawn ( str 5) in CC
