Take note that yellow has some advantages here, but red is hardly out of the game. If you distribute a pillar with your opponent's color in it, you give them a possible move. Thus, circling back around may bury their color again.
Tall pillars let you make major decisions about the landscape of the board. Ideally they will have only your color and white in them.
