Gokyo Shumyo, Section 2, Problem 4 / Attempts

xela: White 'a' next and black is short of liberties.

This in my opinion refutes B 15 as white's response, but then again so does C 17. I do believe this is the correct first move, but we need a correct 'main line' to go into the solution. Here's what I've got:

White can play 6 at 7 of course, but then he has a problem:

Other responses look equally bad:

Black's best resistance is with C18 in my opinion, but nothing seems to work against white B 18.

--gnostic?

White's 1 move is the key. Black then may respon with any number of moves, but it is futile if played correctly.

Other moves.

LukeNine45: This is ko after Black at a next, no? Can you refute the solution given at attempts?

LukeNine45: Also what are the refutations to the two natural responses?
