A high dan-level player ( to which our programs aspire ) would play it properly.
I'm a mid-kyu player, and I find these solutions about half the time, and half not; that's why I am not a dan-level player, lol. GnuGo does have a method ( dragon status ) to explicitly ask "is this group alive or dead?" Correction to my post: the title is Rescue and Capture. ________________________________ From: Stefan Kaitschick <[email protected]> I wouldn't consider not solving this pathological. I think it's a pretty difficult problem. Without a "problem warning" most amateur players would miss it too. You can't force life and you can't force connection. The either-or is easy to miss.
