a Dutch computer scientist, [https://en.wikipedia.org/wiki/Information_technology_consulting IT consultant], and as computer chess programmer author of the chess engines [[Bright]] and [[Spark]], which both support the [[UCI]] protocol.
While Bright utilize a [[0x88]] [[Board Representation|board representation]], the later Spark started as [[Perft|perft framework]] using [[Bitboards|bitboard techniques]] and experimental program to explore new ideas in [[Search|search]] and [[Evaluation|evaluation]].

Quote by Allard Siemelink from the [[Frank Quisinsky]] interview published in the German online chess magazine ''Schachwelt'' <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>:
In 1999, when I was working as an [https://en.wikipedia.org/wiki/Information_and_communications_technology ICT] consultant for [https://en.wikipedia.org/wiki/CMG_%28company%29 CMG] (now [https://en.wikipedia.org/wiki/Logica Logica]), some colleagues started a company competition for who could write the best chess engine. It took me two weeks to create something in [[Java]], and although it was slow and only searched 5 plies deep, it did manage to beat the competition, which incidentally consisted of the two tournament organisers themselves only. Later, when I first learned about [[Bitboards|bitboards]], I just had to give that idea a try and I wrote a new Java engine based on that technique. And although it eventually did fairly well (it was probably 2500-2600 elo'ish), it turned out that Java just wasn't fast enough to be competitive. Have become fully infected by the computer chess virus by that time, I switched to [[Cpp|C++]] and eventually I created Bright.
