Re: C0ckblocker always taking my spotlight!!
Win over all the target's friends when you open the set win over the others then work on your target. It is an avoidable situation,concentrat ing you whole game on one person makes you look like you have an agenda. Being social and friendly with everyone you are fun, outgoing, independent, and not scared of anyone. Kino everyone heck even if someone bumps into you passing by kino whilst you acknowledge them.
Also maybe she isn't trying to cockblock as much as she may just be competing for your attention, her attention or possibly both so being more inclusive towards her would definitely help disarm.
Learn to be a better person not a better player.
