Actually this is not obvious. If you are able to replace the White Choice gadget shown at page V in this paper: https://tromp.github.io/lad.ps with an equivalent Go gadget that doesn't capture any stone then I believe you actually prove that first-capture go is PSPACE complete. --Marcel On 18 June 2018 at 20:17, Marcel Crasmaru <crasma...@gmail.com> wrote: > You can also find here one of my attempts to create a difficult Robson > like problem on a Go board but I guess I've run into difficulties and > didn't finish it: > > https://senseis.xmp.net/?Crasmarum%2FStrangeTsumego > > However, it might help you understand how to convert Robson's problem > instances to equivalent Go positions. > > --Marcel > > On 18 June 2018 at 18:42, Mario Xerxes Castelán Castro > <marioxcc...@yandex.com> wrote: >> Thanks you very much, Marcel.
