Blind Draw Cornhole "Walker"

So, what is a "Walker" in a blind draw cornhole tournament?   A "Walker" is used when you have an odd number of players.   How it works is you draw from a bag a numbers to see who you will partner with.  In that bag are 2 duplicate numbers for every player combo.  However, there is just one single number in the bag for the odd person to draw.   That number for the "Walker" is made public to everyone BEFORE the drawing begins and it is put in the bag.   If you draw that pre-designated "Walker" number, then you will be your own partner.   That means you will play both ends of the boards and toss against each partner of the opposite team for the entire Blind Draw tourney, hence walking between the boards (Walker).
