download Ghost 2 (32-bit version)

Install guide (64-bit version):

• Untar the downloaded archive:
  tar xzfv ghost2_x64_linux_v2.0.1.tgz
• The archive contains the following files:
  • ghost2/ghost2_x64_linux_v2.0.1: The engine (which can be executed without having the other files)
  • ghost2/settings.cfg: Optimized settings (use the command line option --read_settings settings.cfg)
  • ghost2/kp_kp.gbb: Ghost Bitbases (king+pawn vs king+pawn)
  • ghost2/kpp_kp_ram.gbb: Ghost Bitbases (king+pawn+pawn vs king+pawn with one pawn ram)
• Ghost 2 works best under XBoard:
  • cd ghost2
  • xboard -fcp "./ghost2_x64_linux_v2.0.1 --xboard --read_settings settings.cfg"
• Always set the --xboard command line option (except when using the console mode).
• --help will show the help screen.

Tuning guide:

• Always load the optimized settings: --read_settings settings.cfg
• Increase the transposition table (e.g., --hash trans 1G)
• Check whether the bitbases files (kp_kp.gbb and kpp_kp_ram.gbb) are in the same directory as the executable
• If you have Nalimov tablebases, load them using the following command line option:
  --tb nalimov 8M /path/to/tablebases
