Map Selection

Each team blindly (as in, unknown to the enemy team) bans 3 maps for each series. There are 4 possible ways the overlap of banned maps can be:

0 map overlap:
* The only unbanned map is marked as map #1, kniferound for side selection.
* The loser of map #1 bans 1 map of the 6 unplayed maps.
* The winner of map #1 bans 1 map of the 5 unplayed/unbanned maps.
* The loser of map #1 bans 1 map of the 4 unplayed/unbanned maps.
* The winner of map #1 bans 1 map of the 3 unplayed/unbanned maps.
* The loser of map #1 picks map #2 (from the 2 unplayed/unbanned).
* (if a map #3 is required, they play the last unbanned/unpicked map)

1 map overlap:
* The two un-eliminated maps are maps #1 and #2 (kniferound with the winner deciding which map to play first, loser of kniferound picks starting side for map #1)
* Should a 3rd map be needed; there are 4 maps available (the commonly banned one is removed, along with the two played maps).
* The loser of map #2 bans a map (making 3 unplayed/unbanned)
* The winner of map #2 bans a map (making 2 unplayed/unbanned)
* The loser of map #2 picks a map (of the 2).
* The winner of map #2 selects side.

2 map overlap:
* 3 maps remain unbanned, kniferound for who decides map #1
* loser of map #1 decides map #2 (between the other 2 unbanned/unplayed maps).
* if there's a map #3 it's on the unbanned/unplayed map

3 map overlap:
* All 3 banned maps are veto'd.
* Kniferound. Winner picks map #1 (of the 4 unbanned maps)
* Loser of map #1 picks map for map #2
* (if a map #3 is required, the loser of map #2 picks the map for #3).
