Belly attachment  

The belly attachment, W1 in the diagram, is a variety of attachment on the side of two enemy stones. black+circle is the belly being attached to (think of the stone above as the "head").

The belly attachment can be highly effective for living, connecting, capturing, sealing in, or penetrating.

One's immediate instinct in this position is to play at a or b, both of which could indeed be vital points. The interesting thing about W1 is that it takes one of Black's liberties while making these two points into miai, allowing you to take whichever one your enemy doesn't, In situations where either move is useful, that makes this a powerful tesuji.
