If they are overextended then moving in will allow you to catch them most of the time before they can get back safely. Causing them to overextend is also pretty simple. Just suck in lane and they'll end up pushing most of the time. :D --- http://oi41.tinypic.com/9ht4ea.jpg No matter which way you slice it you'll both be ending up in Hell!
I usually just wander through their jungle, then collapse on them. Or I play nocturne and dive bomb them before they know what's happening --- "I read this as a Bannanable Offense. I was like, what ksing with Soraka?"-Kirby 1207 http://us.battle.net/d3/en/profile/CommanderKJK-1173/hero/60977
