Solution.

Once the reader spots the tsuke-koshi tesuji of B1, reading out the rest is very easy. Of course, for those who never seen such a move before, then B1 would not be very obvious. Note that unlike the usual tsuke-koshi play, this tsuke-koshi of B1 is not followed by a cut.

[Diagram]

Variation 1.

If W2 plays below B1, then B3 connects the B1 stone back and threatens to cut at W4. When W4 connects, B5 destroys the eye on the edge.

[Diagram]

Variation 2.

If W2 plays the clamp, then B3 simply connects. There is still no eye on the top edge.

[Diagram]

Failure.

If B1 makes a hane, then W2 blocks. B3 is forced to connect, and W4 connects too. The edge is a five-in-a-row on the second edge, which gurantees an eye there, so White lives.

[Diagram]

Failure.

B1 is played in the wrong order. W2 descends and lives.
