'''RofChade''', (rofChade)<br/>
an [[UCI]] compliant chess engine by [[Ronald Friederich]], written in [[Cpp|C++]]. While its over the board tournament debut already occured at the [[PT 53]] in Spring 2018, RofChade was first released in August 2018.
Despite initially using a [[Tapered Eval|tapered eval]] of [[Middlegame|middlegame]] and [[Endgame|endgame]] [[Material|material]] and asymmetrical [[Piece-Square Tables|piece-square tables]] only,
albeit [[Texel's Tuning Method|Texel tuned]] and along with a sophisticated [[Parallel Search|parallel search]], RofChade '''1.0''' nevertheless aleady played in the 2700+ Elo range <ref>[http://www.computerchess.org.uk/ccrl/4040/cgi/engine_details.cgi?match_length=30&each_game=1&print=Details&each_game=1&eng=RofChade%201.0%2064-bit#RofChade_1_0_64-bit RofChade 1.0 64-bit] in [[CCRL|CCRL 40/40]]</ref>.
