This position chills to +1 3/8.

One more number

White can play to a position worth +1/2 (chilling to +1 1/2).

White plays first

The key point now is a.

Black can play to a position worth +2 1/4 (chilling to +1 1/4).

Black plays first

To evaluate the black follower, let's look at its black and white followers.

Black plays twice

reverses to a position worth +3 (chilling to +1).

White responds

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
