'''Bright''' (Brightchess),<br/><br />
an [[UCI]] compatible chess engine by [[Allard Siemelink]], written in [[Cpp|C++]] based on the [[0x88]] board representation, running as 32-bit executable under [[Windows]]. <br />
Bright's complex [[Evaluation|evaluation]] considers things such as [[X-ray|x-ray]] attacks on the king. <br />
Allard Siemelink developed a statistical analysis tool to tune it for maximum concordance with human assessment of almost all evaluation aspects based on a large number of quality human games.<br />
Able to [[Search|search in parallel]], Bright basically applies a [[Young Brothers Wait Concept]] algorithm. Since splitting is a cheap operation in Bright, avoiding an expensive copy of the board and associated data, the [[Search Tree|search tree]] can be split at any [[Depth|depth]], maximizing the use of the otherwise idle cores. <br />
[[Late Move Reductions]] as popularized by [[Fruit]] and [[Glaurung]] are used in Bright with different implementation details. The reductions are not [[History Heuristic|history]] based, and all moves, except the first one, can be reduced by one [[Ply|ply]] depending on static criteria <ref>[https://www.schach-welt.de/schach/computerschach/interviews/allard-siemelink-deng Interview with Allard Siemelink] by [[Frank Quisinsky]], [https://www.schach-welt.de/ Schachwelt], January 10, 2010</ref> .<br />
<br />
=Tournament Play=<br />
Bright played a strong [[CCT11]] and became runner-up along with [[Fruit]] behind [[Rybka]], and after Rybka's disqualification in 2011 co-champion <ref>[https://cctchess.com/previous-events/cct-11/results/ CCT11: Bright by Allard Siemelink and Fruit by Fabien Letouzey are Co-Champions] (dead link)</ref>. <br />
