Penguin v13   -  PGN Editor for Chess


Penguin is a PGN viewer / reader / editor and desktop board for the review and analysis of games of Chess.

It can interface with UCI chess engines to analyse game positions.

It contains a database of opening positions from the world's premier tournaments to enable the user to explore the most popular lines of opening play.

Penguin is a freeware program for Windows, and is available from this web page.

Use Penguin to
  • Store and replay your games and the games of the professionals.
  • Launch a quick chess board from your desktop.
  • Analyse game positions with the help of a UCI game engine and identify the best sequence of moves.
  • Guide you along the best lines of opening play, lines favoured by the top professionals of today.

Penguin is the effort of one single programmer.  My objective was to create a compact, non-commercial product that could stand alongside the existing editors and offer some original functionality.  I hope that you will find it an enjoyable and useful product and that it will help you improve your skill at Chess.

July 2016.  Version 13 of Penguin was released.  Penguin is now available in two versions: standard and portable.

UCI Chess Engines

Penguin can interface with chess engines that support the Universal Chess Interface ( UCI ) protocol.

Chess engines are stand alone executables that form the computational core of a chess playing program.  They can analyse game positions and suggest best moves.  If an engine supports multi best line analysis then the relative strengths of different moves can also be obtained. 

No UCI engine comes packaged with Penguin.  Users will need to download their own.  There are many UCI engines available for download and most will require no special configuration or setup.  Penguin is not a chess playing tool ( i.e. human vs. computer ) but a tool for game analysis, so not all engines will be suitable for use with Penguin.

  • Some engines are slow to start.
  • Some engines do not support multi best line analysis ( multiPV ).
  • Some engines are not freeware and may require registration.
  • Some engines run by default in GUI mode and require a command line parameter  to force them to run as a background process.

64 Bit Engines.  Many chess engines come in 32-bit and 64-bit versions.  64-bit engines will only work if you have a 64-bit computer.

The following UCI chess engines ( 32-bit versions ) require no configuration and work well with Penguin.

  • Critter 1.2
  • Fruit 2.3.1
  • Gambit Fruit 1.0 Beta 4bx
  • Houdini 1.5a w32
  • Rybka 2.3.2a mp 32-bit
  • Stockfish 2.1.1 JA
  • Toga II 2.0 SE
