IPPOLIT is an open-source chess program released by authors using pseudonyms, Yakov Petrovich Golyadkin, Igor Igorovich Igoronov, Roberto Pescatore, Yusuf Ralf Weisskopf, Ivan Skavinsky Skavar, and Decembrists.
The program is a console application that communicates with a chess Graphical User Interface (GUI) via standard Universal Chess Interface protocol. IPPOLIT is a bitboard chess engine optimized for 64-bit architecture with native support for both 32-bit/64-bit Linux and Windows operating systems. According to recent testing, it is one of the stronger chess programs.[2]
Releases
- IPPOLIT, released on May 2, 2009, was the first release of the series. It was split in multiple usenet messages.[3]

IvanHoe uses a decrementing versioning scheme. The latest release includes source-code for a Java GUI, ComradesGUI.
Controversy
IPPOLIT was initially prohibited from many computer chess websites after the author of the chess engine Rybka claimed it to be a clone of his program.[4] IPPOLIT authors have denied the accusation.[5] Even today, some chess rating lists still refuse to include it in their lists of tested programs.
