Semedori? Not!

Though W3 is sente after a or b is played by white, B4 is enough. Black still has five points of territory: 3 empty intersections + 2 for the capture of W3. Black need not actually capture W3.


Lynx: If W plays, couldn't W reduce it to only 4 points, by semidori? W could play a peep to the stone, then force B to play another move inside by semidori.
