See Ghost pointer ???

Hi guys,
Which pointer should i use for see ghosts ? I mean BasicPlayerInfo Pointer or PTR (player pointer)
btw
what is the defferece
I'm not good in codding so far but i managed to make a undetected hook. Now for see ghos i am using 0x9FF15C i found it when i search for the addys but i dont know is it this. If its not how to find the real. Say only the string name that should i use. OK that is for now hope somebody to help and thank you !

btw PTR isnt player pointer .. it is just a sort form of Pointer.
if u want to say player pointer fast you should say playerptr
