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. 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. The opening book is collected from the website of //ElephantBase//. HGM developed a chess-like Chinese Chess GUI for WinBoard.
