hahahahah, you learned to play from a fortune cookie and watching the karate kid.Look at the field first - it may not lend itself to locking down from back centre, or pushing snake.
As a general rule though, play it as you would normally - if you like to get up in people's grills then do that. If you prefer to sit back, take a G then push, then do that.
There is no definitive answer as it depends on so many variables.
Yep, and all those games I still shot more people than you. Even when I wasn't allowed a gun on field. As for my prowess at 3 man, playing 7 man with you was like 3 man given the amount of 2, or maybe 3 for 1's you got us pulled on.At least I learned to play. Oh, and lock my maxflow down so I can take a gun on-field, put my pack on and remember that my straight shot IS around my neck when shooting custard.
