Beginners Endgame Exercise 1 / Miai Value

Black first

is gote: is sente and White can play it any time

Let's fix the count at 4 here

White first - Black's basic answer

is sente as it can revive he 4 stones After , White can play sente again with

White gote

Then -- is gote and the count is 0

Black sente

turning here is sente because next it would make more in the follow up than it makes here.

If is allowed to capture here, then after and at , Black makes another 4 points. If White omits , then Black can destroy at least another 2 points.

Hence this is the eventual count of White going first: 1

White first - Black's tesuji

After this exchange the count is fixed: a, b and c are all dame and the count is 1.

White first - Charles' move

Since Black can next answer a with b, this variation too leads to a count of 1

Hence the value tree looks like this

```               1 (3)
/   \
4 (1) 1
/ \
5   4
```

and White is a 3 point sente move, Black being a 3 point reverse sente
