Also im not sure this really fits in but it proves to be useful.
Ok when you see someone what do most people do? They Shoot. But what i have found to be really effective is to not shoot get him to follow you thinking that you DONT see him then when you duck behind a wall wait for him, garentee he comes looking for you. Its called Mind Games. All snipers use it in the Military. Alot of people have the same skill in shooting their weapon but the smartest always come out on top. Hope i helped. Sorry for being off topic.

Kinda blazeed lol
