FIDE player card for Vasik G Rajlich

(born Mar-19-1971, 51 years old) United States of America

[what is this?]
Vasik Rajlich was born in Cleveland, Ohio. He grew up in Prague, and has dual U.S. and Czech citizenship. He is an International Master, but is best-known as the author of the computer chess program Rybka (Computer). He is married to IM/WGM Iweta Radziewicz Rajlich, and currently resides in Budapest.

In 2011, the International Computer Games Association (ICGA) found that Rajlich had plagiarized two other programs, Crafty and Fruit, disqualified him for life from competing in the World Computer Chess Championship and all other ICGA events, and stripped Rybka of the championship titles it had won in 2006 through 2010.

Kibitzer's Corner
Feb-26-06  mj29479: This guy is author of Rybka (Computer) the result percentage definitely favours his opponents unlike his chess engine :)) although i must say they share almost identical chess knowledge :)))
Mar-07-06  EmperorAtahualpa: IM Vasik G Rajlich is married to WGM Iweta Radziewicz.

For a recent interview, go here:

May-07-06  chessmoron: In an interview for Arena, he wants to meet Brad Pitt and Veronica Varekova
Jun-11-06  cotdt: Rajlich could beat Rybka, just that Rybka plays much more consistently and calculates better.
Jun-11-06  Dionyseus: <Chessmoron> Actually the interviewer joked aroud saying Vasik will soon become famous and that he would be able to meet Brad Pitt and Veronica Varekova. Vasik said that he doesn't know why he would want to meet Brad.

Here's the interview:

Nov-05-06  fgh: I knew it! The first time I saw this guy's face I felt there was something Czech about it. But good to know, the strongest avaible chess program was made by an Czech!
Jan-30-07  cpoc: <fgh> <guy's face I felt there was something Czech about it> Name Rybka is also suspicious to Czech ear :)
Sep-24-07  Resignation Trap: <fgh> This is what a Czech face looks like? : .
Sep-24-07  cotdt: rajlich looks like booby fischer
Premium Chessgames Member
  WannaBe: <cotdt> I wouldn't know, never seen/met Booby.
Sep-24-07  mrbasso: He won his title by participating in numerous Kecskemet and First Saturday events. I doubt he ever had International Master strength.

  WannaBe: His FIDE card says IM title: and federation of USCF, his USCF card says he has not played in an USCF rated tournament since 1999:
Dec-22-09  zanshin: This is a very sparse bio for someone as dominant in the field of chess engine programming. I suggest a chessgames biographer add some details from

Some interesting parts:

His father teaches computer science at Wayne State University, in Detroit; his mother trained as a mathematician; and two of his brothers are computer scientists. A third one, the black sheep, is a doctor.

Finally, his savings and his morale both nearly depleted, he broke the rating barrier, getting as high as 2440—earning him the international master title—before another decline forced him to realize that he’d never make grandmaster. So he set his sights on a new brass ring: writing the strongest chess-playing program in the world.

”I figured there were about 2000 people in the world stronger than me in chess,” he says, ”but not one chess player that was stronger than me in programming.”

Dec-30-09  zanshin: Pretty good interview with Vas covering his life, Rybka, his co-workers, plans for Rybka and his future in general:

  Stonehenge: <You are a reliable and helpful person, honest through and through. Intellectual independence is an essential virtue: each and everyone must take one's responsibilities and accept the consequences of one's faults.

You avoid underhand manoeuvres and scheming like the plague! Your unfailing sincerity commands your entourage's consideration. You fight shams and all forms of hypocrisy>.

Jul-01-11  Reggaalex: CHEATER.
Jul-01-11  Ragh: <Vasik Rajlich, the creator of Rybka, plagiarised volumes of code from two pre-existing chess engines called Crafty and Fruit.

He's been stripped of his titles and ordered to return all the prize money. >

Jul-01-11  Bratek: <Apparently ICGA has a rule that every programmer who enters its annual world computer championship tournament has to be aware of: namely, that plagiarism will not be tolerated. Levy is using this rule as the excuse for disqualifying Rybka. Me thinks that why stop there: disqualify EVERY programmer! Chess players may not cheat, but they copy like whores!>
