Practical Endgame Test 3 / Solution - White

First, the upper left  

The best that I could find was White 1. Compared to simply exchanging 5 for 6, this is two points better in sente. Since it threatens the corner group's life it is absolute sente for White.

Next, the upper right  

In the upper right, White 1 here seems best. It threatens to cut at 2 so Black has to answer at 2 himself. Despite the connection Black is short of liberties and must submit at 4 and 6. White keeps sente again.

Bits and pieces  

Finally there are three one-point plays left. All are one-sided sente but 3 is the smallest so White will get two of them as long as she starts with 1 or 4.

It looks like White has 30 points to Black's 27; W +3
