Beginner Exercise 11 / Solution
Here I present a solution, which I attempt to make as simple as possible, as well as involving the smallest area on the go board as possible. There are other possible variations, please see /Discussion. --unkx80

There is death in the hane. Black reduces White's eye space twice, and then makes the nakade (placement) inside, reducing White to one eye. If White captures at and , Black can answer at and and White has no way out.
Note: can be played at a instead. Likewise, can be played at b instead.

If White descends at , reduces the eye space further and makes a placement, reducing White to just one eye. captures two stones...

makes a throw-in and turns it into a false eye. If White tries to escape with , Black makes a net with . It is not possible for White to get out.

is tricky. is one way, but there are other possible answers. When captures, Black can actually defend at as White has not enough eye space.

In the Solution diagram, when captures a stone, Black should refrain from playing the atari at . It gives a possibility to open up a ko. If Black tries to avoid the ko with onwards, eventually he is caught in a net by and still has to fight the ko.

here is acceptable. After , now can make the atari. There is no way for White to open up a ko.

The placement in the middle results in a seki.
