I was very happy & proud when I solved that problem some 5 years ago (found the first move), then another one and made some small error some 20 moves later.

Those who are up for a challenge may want to consider this slightly different problem (also cut away the excess from Kirby's problem with a shorter ladder-breaker). The thing about the problem posted by Kirby is that E13 is suboptimal play from White in response to Black E14:

Ko.
at x, as Kirby has it, is much harder to punish, but if punished correctly leads to unconditional capture of the white stones. This is also a double ladder breaker, but it only gives black a ko, instead of an unconditional kill
