One More Number
This position chills to +1 3/8.
White can play to a position worth +1/2 (chilling to +1 1/2).
The key point now is a. Black can play to a position worth +2 1/4 (chilling to +1 1/4).
To evaluate the Black follower, let's look at its Black and White followers.
B 3 reverses? to a position worth +3 (chilling to +1).
W 4 reverses to a position worth +1 1/2. (The chilled value is the same, since each player has made the same number of plays.) The Black follower, chilled, is { 1 | 1 1/2} = 1 1/4 So the original position, chilled, is { 1 1/4 | 1 1/2} = 1 3/8 This is a copy of the living page "One More Number" at Sensei's Library.
