Houdini 3

on


For your info, at the same 2'+2" TC the current Houdini 3 DEV version scores 57.2% against Houdini 2.0 (+50 +/- 4 Elo), and 60.2% against Houdini 1.5 (+72 +/- 4 Elo). Again using 9,000 game test matches.

edit.23.09.2024: The old entry praises Houdini 3. But you should know that this engine later aroused a lot of controversy and the author was accused of breaking the license.

In March 2020, an anonymous poster who came into possession of Houdini 6's source code, apparently due to access to a subversion server owned by Robert Houdart, claimed Houdini 5 and 6 were Stockfish derivatives. In summer 2021, the Stockfish team filed a lawsuit against ChessBase to enforce the consequences of the license termination concerning Fat Fritz 2 and the allegedly Stockfish derivative Houdini 6 sold by ChessBase.
