Apr-08-13  Interbond: Have anyone tried the Bratko-Kopec test? How does your score in this test compare to your rating?

Jun-12-16  SimonWebbsTiger: RIP Danny Kopec.

  Sally Simpson: Sad news about Danny passing away.

I have loads of happy chess memories from the 80's when we became friends and we kept in touch with each other over the years. He was quite a character. Not many dull moments....often quite the reverse.

Rest in Peace Danny, Thank you for all your help and encouragement.

  paulalbert: I just learned of Danny's death. I had attended many of his summer chess camps, and Danny authored along with GM Lubomir Ftacnik the book on all the 64 games that won my Brilliancy Prize at the U.S. Chess Championship. He just sent out an email ten days ago related to this year's camp and I was about to call him. I was unaware that the medical condition he had seemingly been successfully conquering had taken an irreversible turn for the worse.

He was true lover of chess.

My condolences to his family. May he rest in peace.

  perfidious: RIP Danny.

Our first meeting, at the 1982 New England Open, is a game I will always remember: you sacrificed a pawn in the opening and I hung onto it through over ninety moves and 8.5 hours of play before securing the draw.

Towards the end of that game, you said something--do not recall now what, I was offended and we had words, but we talked about things afterwards and it was simple tension amidst a difficult game. Thereafter, it pleases me to note, we always got on well, including two more tournament games, in 1988 and 1996.

  HeMateMe: what was the illness that affected IM Kopec? I remember seeing his name many times in Chess Life, over the years.
Premium Chessgames Member
  naisortep: RIP IM Danny Kopec, a great player, lecturer, author, teacher and expert on artificial intelligence. Inventor of the Kopec System and the Bratko-Kopec Test.

  kingscrusher: I can't believe this - I played Dr Kopec 3 times recently on the ICC autopairing.

Here is one of the games where he crushed me:

Very sad news

RIP Danny Kopec

  Sally Simpson: Hi Perfidious,

Danny was a bit reckless as far as endorsing himself with the British/Scottish way. When he arrived in Edinburgh with a bang! (that is the correct word.) he put a few noses out of joint with his American straight to the point ways. I thought he was great.

I recall one lad making an illegal against him. Danny thought for 5 minutes to see if he could take advantage of it.

Seeing none he pointed out the error, demanded the player move the touched piece and then wanted his time back!

Although he attended Edinburgh University he had a row with the University chess team (I think Danny wanted paid to play for them) and there was little or no love lost between them though most of the banter was humorous.

Danny played for us, the Edinburgh Chess Club (unpaid but we allowed him to advertise his services as a chess coach on the noticeboard - which we would have done anyway irrespective of who he played for.)

This game.

D Kopec vs M Condie, 1980

Danny missed a wonderful wrap up though went onto win. Next day some of he University players set up the missed brilliancy position on all the 15-20 boards in the analysis room.

Danny did actually find that quite funny.

There were/are quite a few Scottish players, definitely including me, whose Chess greatly benefitted from Danny's time in Scotland.

  Penguincw: Just heard about his death, and I'd also like to offer my condolences.
Premium Chessgames Member
  SteinitzLives: Danny Kopec was a strong and capable chess teacher and he greatly popularized chess camps in the U.S..

His old videos on pawn structure (back when there were few resources at all on them) tied to specific opening formation was fantastic!

  Sally Simpson: Hi HeMateMe,

"(1985) Master Chess: A Course in 21 Lessons."

This was co-authored with me, Ian Mullen, Chris Morrison and Nigel Davis.

Ran through three publishing houses and 21 reprints (possibly more, all I know is up until 2010 I was still getting a cheque every April for something I wrote in 1984.)

When it first came out the authors were listed in alphabetical order and sometimes it read 'by Chandler et al...'.

Danny was not too happy with that. Quite rightly so, it was his idea and he did all the spade work regarding the organisation and meeting the publishers. I thought it was quite funny. Danny says they be will confusing me with Murray Chandler. I said that's good. He's a Grandmaster.

I wonder how many people bought it thinking I was him! There again I wonder how people bought his books thinking he was me! :)

Danny wrote to various places and it was soon appearing as Danny Kopec et al.

It was also translated into Spanish. That was odd seeing something you had written and not being able to read it.

I've never met Nigel which is also pretty strange since we wrote a book together.

Every now and since I heard of Danny's passing another wee nugget of a happy or funny memory drops by. They were good days.

  HeMateMe: Did he have cancer? Heart disease?
Jun-14-16  belgradegambit: In our youth I lost to him on the black side of a Kopec Sicilian. I wasn't that bad out of the opening but I was intimidated by our ratings difference. RIP Danny. As an aside, having suffered a near death experience last year I actually found (near) death to be incredibly peaceful.
Jun-15-16  kamagong24: The Kopec System!!!

RIP Danny

Jun-15-16  Granny O Doul: Pancreatic cancer is what I hear.
Premium Chessgames Member
  paulalbert: I was honored to be one of the speakers at a memorial event for Danny at the Marshall Chess Club in NY on Tuesday, June 28. Along with Danny's wife Sylvia and son David were many other relatives as well as chess friends, including Danny's young chess students, and also fellow professors and students from Brooklyn College where Danny was a tenured professor of computer science and artificial intelligence.

Given Danny's extensive chess activity as a player, lecturer, coach, and author, and summer chess camp entrepreneur, it is amazing that chess was really a hobby, along with a lot of other interests and projects outside his full time and demanding job as a professor and author of books and papers, and full time teaching responsibilities. In many ways Danny was a polymath, fluent in 5 languages for example. One of his nephews made an interesting comment that he always regarded his Uncle Danny as a genius.

Fortunately, I guess anticipating that he might not beat the pancreatic cancer that took him away too soon, Danny made provisions that his long time friend GM Lubomir Ftacnik would be able to take over all the teaching responsibilities at this year's adult only chess camp which starts July 11 in Bennington, VT, with Sylvia and David as always taking care of the administrative aspects. I am pleased that I can attend, and Lubomir who has been at the camps before is a superb teacher. However, we sadly will miss Danny's unique exuberance.

I hope it is not against Chessgames rules to mention it, but Danny's family has requested that anyone wishing to remember Danny do so by donating to the Pancreatic Cancer Action Network ( ).

Jul-26-16  Conrad93: Kopec had absolutely no ego, and really loved the game. The chess world needs more people like him.
