shinkenjoe: Wouldn´t white sacrifice the three stones to live in the corner ? something like this ?

gogobera: so, is this an overplay by white??

zxb: yes, this is still an overplay by white. If white sacrifice the three stones to live in the corner, you can see how black's stones all become connected and strong, while white's left group still needs to crawl on the second line for life. Black's position is much, much better than white's.
