White to play.

Roadblock. A roadblock is a task that only one person can do. In this roadblock, the task is to find the best sequence of moves for capturing the three BC stones.

War Eagle: How about W1?


[Diagram]
White 1 roadblock

W1 either starts a ko at a. If Black connects at a, then White at b will cut off the six black stones.

HolIgor: there is a better sequence for White.

unkx80: To War Eagle: Sorry, but I can't give you the next clue.

How's this?

tywin: W5 at W1. With this sequence, White takes the ko first. If B4 fills the ko, W5 cuts at B4.

unkx80: Precisely the sequence I am looking for. There you go, have the next clue. =)
