White 1 prevents the capture of two stones and makes shape. She has to be careful in answering Black 2 and 4.
The throw in at 1 is tesuji. White can't block at A with 5 because of damezumari, but captures at 1 instead. JamesA: Is it necessary to throw in? can white just play at 3 straight away? unkx80: Both will lead to the same result. =)
After Black capture of two stones with 2, White can recapture at 3, and has two eyes at A and B.
If instead of throwing in, White blocks at 1, Black 2 starts a ko.
White 1 on the 2-2 point doesn't give life. After the connection at 6, White still has only one eye in the corner. Black can also play atari with 2 at 4.
Connecting at 1 is the third way to save the two stones. Black makes a hane at 2 and a placement at 4 and White is dead, because now A and B are miai. Black could also kill playing 2 on the vital point of this shape, being 3.
