A pathological seki
Keywords: Life & Death
If Black plays on a, White answers on b and Black loses the capturing race. I don't know whether this is a classic strange position or not. It doesn't seem likely that such things could appear in real games. I stumbled across it years ago while trying to construct an algorithmic definition of seki. (It convinced me to work on something easier.:-) I think it's interesting as a suggestion of how to create sekiish positions with arbitrarily large numbers of shared liberties. -- WilliamNewman
I think the correct way to continue is this, resulting in an "ordinary" seki. Weird position, though. --Dansc
Bill: Nope, but he does lose sente.
WilliamNewman: I have since found somewhat similar shapes
