'''UCI''', (Universal Chess Interface)<br/>
an open [https://en.wikipedia.org/wiki/Communication_protocol communication protocol] for chess engines to play [[Games|games]] automatically, that is to communicate with other programs including [[GUI|Graphical User Interfaces]]. UCI was designed and developed by [[Rudolf Huber]] and [[Stefan Meyer-Kahlen]] <ref>[http://www.playwitharena.com/?Newsticker:Archive_9 Interview with SOS programmer Rudolf Huber in German language!] by [[Frank Quisinsky]], [[Arena|Arena Chess GUI 3.0]] - Archive 9, 132, May 10, 2005</ref> , and released in November 2000 <ref>[https://en.wikipedia.org/wiki/Universal_Chess_Interface Universal Chess Interface From Wikipedia]</ref> . It has, by-in-large, replaced the older [[Chess Engine Communication Protocol]] ([[WinBoard]]/[[XBoard]]).
=Design Philosophy=
The UCI capable [[GUI]] is not only View and Controller of a chess [https://en.wikipedia.org/wiki/Model%E2%80%93view%E2%80%93controller MVC], but also keeps the Model with its internal [[Chess Game|game states]]. It is also an "arbiter" instance to decide about the outcome of the game, for instance in declaring a game to be drawn after a [[Repetitions|threefold repetition]] has occurred. The UCI GUI may choose and play moves from an [[Opening Book|opening book]] and [[Endgame Tablebases|endgame tablebase]].
=Critique=
While the UCI design makes it simple for engine programmers to integrate a "stateless" chess engine, it was also disputed by various chess programmers, since it subsumes engine control parameters and delegates possibly game decisive stuff to the GUI.
==Contra==
Excerpt concerning UCI from a [[Robert Hyatt]] interview by [[Frank Quisinsky]] in 2002 <ref>[http://www.top-5000.nl/int/crafty.htm Interview with Robert Hyatt] by [[Frank Quisinsky]], May 11, 2002, hosted by [[Ed Schroder|Ed Schröder]]</ref> :
I simply don't like UCI. It subsumes '''all''' engine control parameters. It tells the engine when to [[Pondering|ponder]], when to [[Search|search]], when to stop, etc. That is contrary to my design and I have no interest in hacking [[Crafty]] to support something that is so different from the [[Chess Engine Communication Protocol|WinBoard/XBoard]] protocol that has been around for a '''long''' time and which works '''perfectly'''.
It removes several critical engine-decisions that are best made by the engine, not the GUI.
==Pro==
[[Fabien Letouzey]] emphasize the ease of implementation in a [[Frank Quisinsky|Quisinsky]] interview, April 05, 2005 <ref>[http://www.playwitharena.com/?Newsticker:Archive_7 The alternative to Crafty, Interview with Fabien Letouzey] by [[Frank Quisinsky]], [[Arena|Arena Chess GUI 3.0]] - Archive , Page 7, 96, April 05, 2005</ref> :
The choice of UCI is based on software-design principles that are not easy to explain. It's a programmer's thing really, I don't expect engine users to understand. Let me give you a clue though: think about young WinBoard engines that you have tried; how many handled pondering ... without bugs??? Another clue might be that surely, [[Stefan Meyer-Kahlen]] knows a lot about good programming, right? So trust him if not me, UCI is good for programmers because it leads to fewer bugs in the code ...
Fabien wrote a protocol translation program, [[PolyGlot]] to allow use of the new protocol on [[Linux]], though this is now supported natively by the powerful [[Scid vs. PC]] toolkit. Scid vs. PC itself includes Polyglot code to enable support for Polyglot opening books.
