Fear can break your CC chain mid-burst - Cheap Shot through it if possible, and Kidney Shot immediately after, not wait.
Frost Nova/Blink kiting stalls your opener - Shadowstep or Sprint to close distance before trinketing into the burst.
Whoever lands the first Cheap Shot usually wins the fight - trinket immediately if you're the one CC'd, don't wait for Kidney Shot.
Whoever Cheap Shots first almost always wins - open on their Rogue before he can open on yours if you get the first move.
