Reversi (Cont..)

Advanced Strategies for Reversi

An example of playing for key squares is shown in Figure 2. Here, Black has taken two edge squares along the top of the board and is in good position. Black can now also take the edge square at b1 (indicated by a question mark). However, doing so would be a costly mistake; it would jeopardize all of Black's key positions (b1, d1, and e1). If Black takes b1, white will move into c1, subsequently gain control of the corner, and wipe out all of Black's edge positions (Figure 3 shows the end result). Black must do something else instead; just about anything else would be a better move.
