Overall strategy
  - Aim for an efficient use of the tiles, in a way that helps 
    the board.

  - Be willing to sacrifice several turns per game, for some combination 
    of the following:
      - Opening up the board
      - Safely disposing of C's and V's
      - Redrawing

Rack management
  - When holding more than 1 S, or more than 1 blank, favor immediately 
    redrawing the extra S or blank, unless a bingo is available.
  - An extra S or blank will otherwise tend to be used inefficiently, 
    leading to fewer bingos in the game. 

  - When holding 3 or more S's and blanks combined, consider redrawing 
    even if a bingo is available (unless there's a spectactular bingo 
    worth at least 100 points).
