A straightforward answer this month. White can kill, Black can live.
"White can kill"
White 1 threatens a capture and Black cannot connect - he would then have 3 stones in atari. Therefore 2 is the best move, aiming for an eye at 1.
However 3 is a clever move that falsifies the eye at 1 - White can atari on the right, or if Black connects, an extension from 3 to the 1-3 point puts the 3 stones in atari.
"Black can live"
Playing 1' at 2, 7 or below 4 result in a ko. Playing 1' at 6 fails. Playing 1' at 5 starts an alternative successful sequence.
