? about Connect 4

First Merry Christmas. Ok, so earlier the this morning I was playing Connect 4 with my little sister and got to thinking if there is something to whom ever goes first. I am wondering if there is something to this? I am sure you are all farmilar with this game is uses two color chips Red/Black and the playing board is 7 squares wide and 6 tall. And also is there any certain kind strategy other than just traping your opponent much like poker? Any ideas?
Thanks
