The first move is probably the hardest one. Why not 2-2 or 4-2 ? We'll investigate that later. Actually, this problem looks harder than it is. When looking at it from White's standpoint, it is quite easy to find the correct move on the spot.
White can enter Black's EyeSpace from two sides: at a or b. Black has to find a move which protects against both. Let's analyze some failures first.
Simply closing off at 1 is not good. White 8 makes miai of a and b.
If Black closes off the other side, White breaks in from the first. Up to 10, Black makes a (slightly modified) door group which is dead.
Here a and b also fail to protect against White 2. So let's investigate the last candidate, c.
Black 1 fails to protect against the jump to 2. His eye space is sufficiently reduced. The rest of the moves are for reference.
If White plays 2 or a, Black protects at 3 and makes such nice shape that it isn't even necessary for Black to respond to White 4. We'll analyze this in KanazawaDerivedProblem56.
