Belly attachment  

The belly attachment does the trick. In this particular situation, it is known as attaching at the belly of the weasel (in Japanese, itachi no hara-zuke). Itachi no hara-zuke is considered a proverb, probably best translated as "Attach at the belly of the weasel [in situations like this].

Continuation 1  

After the continuation to W7, which of course Black would not play out, White wins the capturing race.

Continuation 2  

If Black fills outside liberties first, he still loses the semeai.

Zokusuji  

W1 is zokusuji: a crude move which doesn't work. The best result White can get now is ko.

Zokusuji cont 1  

If White protects at W3, B4 kills her.

Zokusuji cont 2  

Persevering with W3 makes it ko. The ko is very disadvantageous for White. There is no need to make it ko if you can win unconditionally. W5 could also be at a. The continuation is left as an exercise. It's still a ko.

Another corner problem  

Note that this problem is a different beast altogether! For the solution, see two stone corner squeeze.
