From Interview With The Author

Houdini is very good in defending difficult positions (even against other top engines), and its tactical prowess is literally super-human. I�ve always tried to keep the style of Houdini quite aggressive � it consistently has the lowest draw rate of all the engines in the rating lists. Against 3000+ opponents Houdini has a lower draw rate that what you can observe in the average human GM tournament.
