'''Delfi''',<br/>
a [[WinBoard]] and later [[UCI]] compliant chess engine by [[Fabio Cavicchio]], written in [[Pascal]] with [[x86]] [[Assembly#InlineAssembly|inline assembly]], compiled with [[Delphi]], first released in August 2001.
Delfi was distributed within a software suite as '''Delfi Trainer''', along with an own [https://en.wikipedia.org/wiki/2.5D 2.5D] [[GUI|chess GUI]], an ergonomic [[2D Graphics Board|2D graphics board]] in [https://en.wikipedia.org/wiki/Bird%27s-eye_view Bird's-eye view] and pieces with 3D-effect, and a position trainer <ref>[http://www.msbsoftware.it/delfi/ Delfi Winboard - UCI Engine]</ref>.
The WinBoard/UCI compliant Delfi '''5,4''' is now freely available, the earlier Delfi '''5,1''' is [[:Category:Open Source|open source]] with a license allowing modification for personal use but no redistribution or playing in public tournaments <ref>[http://www.msbsoftware.it/delfi/source.htm Delfi - Winboard chess engine - source]</ref>.
=Description=
Delfi uses the [[Vector Attacks|vector attacks]] approach of a [[Board Representation|board representation]] with a 16x12 board, combining the property of the [[10x12 Board|10x12 board]] with its surrounding [[Ranks|ranks]] and [[Files|files]] with the property that a square difference uniquely maps a [https://en.wikipedia.org/wiki/Euclidean_vector vector] in the [https://en.wikipedia.org/wiki/Chebyshev_distance Chebyshev] [https://en.wikipedia.org/wiki/Vector_space vector space] of a [[Chessboard|chessboard]].
Delfi applies [[Principal Variation Search|PVS]] [[Alpha-Beta|alpha-beta]] with [[Null Move Pruning|null move pruning]], [[Futility Pruning|futility pruning]] and [[History Leaf Pruning|history pruning]]. Dual core processors are supported using a [[Parallel Search|parallel search]] with a [[Shared Hash Table|shared hash table]].
=Tournament Play=
Delfi won all the six [[Italian Computer Chess Championship#CIPS|Campionato Italiano per Programmi Scacchistici (CIPS)]] championships it played, from [[CIPS 2002|2002]] until [[CIPS 2007|2007]], and further won the [[CCC 2005|Chess Computer Cup 2005]], and [[CCC 2008|2008]]. At the [[WCCC 2006]] in [https://en.wikipedia.org/wiki/Turin Turin], Delfi performed with respectable 5½/11.
