Fritz 15 Help
especially when multiple threads perform simultaneous EGTB probing. Houdini has been
extensively tuned for this state-of-the-art end game table base system so as to
provide optimum precision and strength in the late endgame at any time control and
with any number of cores. While installing the files on a SSD disk is recommended, the
performance of the Syzygy on a normal hard disk is still very good.
The only drawback of Syzygy bases is that they do not contain the exact Distance to
Mate information. If you require an exact mating distance in a position you'll need an
alternative solution.

Syzygy EGTB
For the Syzygy EGTB support you'll need to install the Syzygy EGTB files. At the time
of writing all the Syzygy files are available for torrent download at http://oics.
olympuschess.com/tracker/index.php. The 3-4-5-men Syzygy are also available for
direct download at http://olympuschess.com/egtb/sbases.
The total size of the 3-4-5-men files is 938 MB (290 files), the 6-men table bases
require 149 GB (730 files).
The location of the Syzygy EGTB files is specified in the SyzygyPath option.

Nalimov EGTB

of writing they are available for download at the address ftp://ftp.cis.uab.edu/pub/
hyatt/TB or http://tablebase.sesse.net. Download the files and save them in a
directory on your hard disk. The total disk space required for the 3-4-5-men table
bases is about 7 GB (290 files). The space requirement for the 6-men Nalimov table
bases exceeds 1 TB.
The location of the Nalimov EGTB files is specified in the NalimovPath option.
