Query: A Classification of Semeai with Approach Moves   The paper analyzes liberty races (semeai) in the game of Go. A rigorous
treatment of positions with approach moves but no ko revealed a class of
positions not described in the literature before.
  The complete presented classification is simpler and more compact than the
one used so far. This was achieved through a classification by the types of
liberties and the order they are to be filled instead of a classification by
group status.
  A principal difference to semeai without approach moves is that in the
presence of approach moves and shared liberties and the absence of eyes, two
different strategies are possible because the un-orthodox filling of shared
liberties instead of outer liberties may be a better strategy.
