I’ve played a few games against HaChu 0.18 on my new laptop. The change of CPU (O/S unchanged – Fedora 20 – I threw Windows 8 away after 5 minutes of checking that the hardware was working) causes HaChu to select different opening moves. In particular, as gote, it moves the Lion out first move, and attempts to win my Go-Between. It also came up with an interesting new variation. More on that when I resume my blog posts on that opening line.
