'''Vincent Diepeveen''',<br/>
a Dutch chess programmer and chess player, author of the strong chess program [[Diep]] and [https://en.wikipedia.org/wiki/FIDE_Master Fide-Master] in over the board chess. He started chess programming in 1993, first the program [[Grijp]], a team effort with [[Remy de Ruysscher]], and in January 1994 with Diep <ref>[[Eric van Reem]] ('''2004'''). ''Drei Gewinner in Leiden - Die Geschichte von Diep''. [[Computerschach und Spiele]], 6/2004 (German)</ref>. Since the mid 90s until 2007, Vincent almost played each over the board [[Tournaments and Matches|tournament]] in Europe with Diep, since 1997 [[World Computer Chess Championship|World Computer]] and [[World Microcomputer Chess Championship|World Microcomputer Chess Championships]], as well as online tournaments. Diep became Dutch Open Champion in [[DOCCC 2004|2004]] and third at the [[WCCC 2004]] in Ramat Gan behind [[Junior]] and [[Shredder]]. Vincent is known as one of the most knowledgeable experts in massive [[Parallel Search|parallel search]] and proposed the [[Double Null Move]] idea. He is also famous for his emotional discussions in [[Computer Chess Forums]] and his animosity against [[Bitboards]] <ref>[https://www.stmintz.com/ccc/index.php?id=173418 On Beowulf - long post] by Vincent Diepeveen, [[CCC]], June 05, 2001</ref> <ref>[https://www.stmintz.com/ccc/index.php?id=266030 Re: Differences between 0x88 ,10x12 and Bitboards!?] by Vincent Diepeveen, [[CCC]], November 19, 2002</ref> and the gibberish of a few academics.

==Vincent==
===1997===
Vincent Diepeveen's early claim caused some trouble and antagonism <ref>[http://groups.google.com/group/rec.games.chess.computer/browse_frm/thread/11e70ee3cec6c75f Unsubstantiated claim in the Diep homepage] by [[Bruce Moreland]], [[Computer Chess Forums|rgcc]], January 17, 1997</ref> <ref>[http://groups.google.com/group/rec.games.chess.computer/browse_frm/thread/a20a25fbec56fd82 Let's stop wasting time on Vincent Diepeveen] by [[Dap Hartmann]], [[Computer Chess Forums|rgcc]], January 23, 1997
</ref> <ref>[[Peter Kouwenhoven]] ('''1997'''). ''DIEP, Deep Trouble''. [[ICGA Journal|ICCA Journal]], Vol. 20, No. 3, pp. 200-203</ref> :
Diep is without doubt the strongest chess analysis program in the world at infinite level (few hours a move). The longer you allow it to analyse the better the move it will produce, something which is uncommon for most other chessprograms, caused by the enormeous chessknowledge in Diep, which is at the time still considerably growing every month (and decreasing the Diep searchspeed).
===1999===
Vincent after [[WCCC 1999]] on [[Cilk]] <ref>[https://www.stmintz.com/ccc/index.php?id=58505 DIEP parallel in Paderborn - technical and detailed story] by [[Vincent Diepeveen]], [[CCC]], June 28, 1999</ref>:
Actually the big professor who has written so many books that i have in my possession was there too: [[Charles Leiserson|Leiserson]]. Lucky i could exchange a few words during the game with him.
Cilk really is a very promising language. In contradiction to all my big efforts to parallellize [[Diep|DIEP]], writing in Cilk this goes a lot simpler. Regrettably when starting the parallel version of DIEP, there was no port of CILK to windows (the first demand for something is that it must work both in windows and linux before i can use it; interface is of course something different) otherwise i might have done better in paderborn.
Anyone who still must start his parallel project here gets a free tip from me:
Don't go fiddle with difficult parallelization, simply use CILK, let that language handle the parallellism and keep only busy making a good program!
The alternative to Cilk is years of bugfixing the parallel code.
==Bruce==
[[Bruce Moreland]] on Vincent in 2000 <ref>[https://www.stmintz.com/ccc/index.php?id=127350 Re: DIEP in WMCCC2000 London - long story] by [[Bruce Moreland]], [[CCC]], August 29, 2000</ref>:
With Vincent, you have to take the whole package. He has firmly held opinions, and when he aims one of these at you, you have to duck and grab your shoes. He also has a lot of insight, he can direct his most cutting criticisms at himself as well as at others, his mother is a great cook, and if you ask him he'll haul you and your computer clear across northern Europe.
