Daniel Kopec, February 28, 1954 – June 12, 2016
Daniel Kopec (February 28, 1954 – June 12, 2016) was an American
chess International Master, author, and computer science professor at Brooklyn
College. He graduated from Dartmouth College in the class of 1975. Kopec
later received a PhD in Machine Intelligence from the University of Edinburgh.
With Ivan Bratko he was the creator of the Bratko-Kopec
Test, which was one of the de facto standard testing systems for chess
playing computer programs in the 1980s. Danny Kopec died on June 12, 2016.
Danny Kopec was one of the more talented home-bred players in the US. Danny
was New York High School Champion at 14, National Master at 17, Scottish
Champion in 1980, 2nd-equal in the Canadian Closed in 1984, and International
Master in 1985. He was an active player, journalist, writer, chess educator
and scholar. His competitive results with top-flight chess professionals
have always been remarkable. He has also delivered many chess courses, lectures,
published seven highly recognized chess books, and has developed eight highly
regarded instructional videos (18.5 hours).
In parallel with his chess career, Dr. Kopec pursued an academic career
in computer science with research in artificial intelligence, software methodology,
and computer science education. For more than 20 years he tested and evaluated
hundreds of human and machine chess players in the UK, Canada, and US in
order to quantify their overall chess strength, their specific deficiencies
and definite abilities. In bridging his chess and academic interests, Kopec
developed a reputation as perhaps the world’s greatest exponent of
chess knowledge.
And here's a video promo for his
DVD seriesHow to Visualize Chess Combinations, produced in
2009.
Finally we bring you a video of Danny Kopec annotating a spectacular game
between Alexei Shirov and Judith Polgar, entitled "Middlegame Pawn
Play for Mate":
Bratko-Kopec test for chess software (PGN)
The following test positions were compiled by Ivan Bratko and Danny Kopec
in 1982 and became an important computer and human testing tool. The 24
positions were meant to mainly measure the positional understanding of the
programs. Nowadays, this test has lost its significance. The toughest positions
for computers are 2, 3, 11, 17, 23, 24.
