HaQiKi D,
a Chinese Chess (XiangQi) engine written by Harm Geert Muller, developed in 2009, and newcomer at the Chinese-Chess Tournament in Pamplona 2009 where it surprisingly won the silver medal ^[1] . The name HaQiKi can be divided into three parts: Ha is the abbreviation of the author’s given name, Qi means Chess in Chinese pronunciation, and Ki represents AI in Dutch. Moreover, the name can be pronounced as Hatsekiedee which is Dutch for an expression of surprise ^[2] . The opening book is collected from the website of ElephantBase ^[3] . HGM developed a chess-like Chinese Chess GUI for WinBoard.
