Quote by Allard Siemelink from the Frank Quisinsky interview published in the German online chess magazine Schachwelt [2]:
In 1999, when I was working as an ICT consultant for CMG (now 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, 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 C++ and eventually I created Bright.
