Houdini is appreciated by many players and even top Grand Masters. In arecent interview, when asked the question "If you had to pick one player to represent earth in a chess game vs. aliens, which active player would it be? You can pick different active players for the white and black side, if you feel it necessary.", super GM Peter Svidler had a simple reply: "Houdini".

From numerous interviews it appears that many top Grand Masters including the current chess World Champion Viswanathan Anand use and appreciate Houdini.
The Chess Club Live Facebook page phrased it like this: "If there ever was a computer descendant of the romantic players like Morphy, Anderssen, Spielmann, Marshall, Bogojulbow, Tal, Nezhmetdinov, Shirov, Morozevich it would be Houdini. Houdini is the current World number 1 chess engine and plays in a very romantic style."
