'''Gaviota Tablebases''',<br/><br />
a [[Endgame Tablebases#DTM|depth to mate]] endgame tablebase by [[Miguel A. Ballicora]], initially developed for his [[Gaviota]] engine <ref>[http://www.talkchess.com/forum/viewtopic.php?t=25311 Gaviota's Endgame Tablebases] by [[Miguel A. Ballicora]], [[CCC]], December 07, 2008</ref> . The probing code, written in [[C]], is open source, along with the tablebase files licensed under the [[Massachusetts Institute of Technology#License|MIT license]]. Gaviota Tablebases [[Memory|cache system]] works like [[Endgame Bitbases|bitbases]] on the fly, allowing to probe WDL information with fourfold increased cache efficiency. Further, the [[Thread|thread safe]] probing [https://en.wikipedia.org/wiki/Application_programming_interface API] allows soft probes to get information from the cache without reading the [https://en.wikipedia.org/wiki/Hard_disk_drive hard disk] - intended to use everywhere inside the [[Search|search]], and the classical ''hard'' probe, suited to use with some distance to the horizon. The up to 5-men tablebase files can be generated <ref>[https://sites.google.com/site/gaviotachessengine/Home/endgame-tablebases-1/gtb-generation Generation from Console - gaviota chess engine]</ref> and checked <ref>[https://sites.google.com/site/gaviotachessengine/Home/endgame-tablebases-1/gtb-checking Checking Files After Generation - gaviota chess engine]</ref> using the free command line program ''tbgen'', performing several compression schemes using ''tbcp'' <ref>[https://sites.google.com/site/gaviotachessengine/Home/endgame-tablebases-1/gtb-compression Compressing Tablebases - gaviota chess engine]</ref>, yielding in 5-men sizes below 7 GB. <br />
