ishi-no-shita

Sometimes referred to as under the stones. Concerns sequences where stones are played on points from where stones have just been captured. Such sequences are hard to visualise and so are ubiquitous in tsume-go. In the example below, the aim is to make two eyes for White. Capturing the single black stone would be a mistake because Black can convert the resulting space into a false eye. However the sequence shown succeeds. White 3 is played on an intersection that was previously occupied in order to capture two black stones to make the second eye.
