GokyoShumyoSection3Problem74/Attempts

Here is my take on this problem, white use two different special-techniques to make a Ko.

[Diagram]

W begin by making a squeeze

[Diagram]

Continuation, W2 at B5, W uses W6 tesuji to increase liberties

[Diagram]

The two hanes gives white an extra liberty making it 4 vs 3 liberties if black tries to avoid Ko
