'''Esc''', (ESC)<br/>
a [[WinBoard]] compatible chess engine by [[Claudio della Corte]], written in [[Cpp|C++]], first released in February 2001.
Esc won the ''2nd Italian Engine Contest'' played on-line in 2001/2002 <ref>[http://www.open-aurec.com/wbforum/viewtopic.php?f=18&t=35745 2nd "Italian Chess Engine Contest", (last round results)] by [[Gianluigi Masciulli|gianluigi]], [[Computer Chess Forums|Winboard Forum]], January 14, 2002</ref> , and participated at three [[Italian Computer Chess Championship#CIPS|CIPS tournaments]], third place at the [[CIPS 2001]] with 3½/5 and [[CIPS 2002]] with 4½/6 repectively, and runner-up at [[CIPS 2004]] with 4/5.

Esc applies a [[Principal Variation Search|principal variation search]] within an [[Iterative Deepening|iterative deepening]] framework, and uses [[Null Move Pruning|null move-]], [[Futility Pruning|futility-]], [[Futility Pruning#Extendedfutilityprunning|extended futility pruning]], [[Razoring|razoring]] and various [[Extensions|extensions]] to sharpen the [[Search Tree|search tree]] as reported in its [[Search Statistics|search statistics]] given in the [[Logging|log-file]] <ref>[http://kirr.homeunix.org/chess/engines/Norbert%27s%20collection/Esc%20%28Compilation%29/v1.16%20CIPS/Esc000.log Index of /chess/engines/Norbert's collection/Esc/Esc 1.16/Esc000.log]</ref> , as well as [[Lazy Evaluation|lazy evaluation]]. Further Esc utilizes three separate [[Hash Table|hash tables]], the main [[Transposition Table|transposition table]], a smaller TT for the [[Quiescence Search|quiescence search]] and a [[Pawn Hash Table|pawn hash table]]. [[Move Ordering|Move ordering]] considers [[Hash Move|hash-]] and [[PV-Move|PV-moves]], winning and equal [[Captures|captures]], and two [[Killer Move|killer moves]].
