well, by the general definition of Mindgames, you can't win without them. Most people just use the term to refer to generally playing smart or strategy, so unless you have such godly fingers that you can play fox and JC shine indefinately and follow rolls perfectly (like in the perfect adventure clear by SDM) you're not going to win without outthinking your opponent every once in awhile.
Don't ever ask, "Who's better, Person A or Person B?", because it leads to the stupidest, most opinionated arguments on these boards and just wastes everyone's time.
PC stands for the county that they're from, I don't remember which one it is, but I'm sure you could use google or search or check one of PC's public profiles.
