Kibitzer's Corner
Feb-16-04  Benjamin Lau: Wasn't he the world junior chess champion at one point?
Jul-18-04  nikolaas: He was indeed. In 1967.
Jun-08-05  trumbull0042: He programmed one of the Saitek tabletop chess computers, called, strangely enough, the Kasparov Trainer. Garry endorsed it and wrote a preface in the instruction booklet, but I doubt he had anything else to do with it.

Oct-26-06  Caissanist: Kaplan was a friend of my Artificial Intelligence (AI) professor in college, and one day he came to lecture about the technical details of his programming for Saitek. It was pretty interesting, but it had nothing whatsoever to do with AI. He had the effect of reinforcing my belief that AI is a crock.

Der in Argentinien geborene Julio Kaplan gehört mit Sicherheit zu den spielstärksten Schachprogrammierern. 1963 emigrierte er nach Puerto Rico, wo er 1967 nationaler Schach Champion wurde. Seinen größten Triumph feierte er ebenfalls 1967 als Jugendweltmeister. Unter anderem vor Robert Huebner und Jan Timman, die beide jahrelang zur absoluten Weltklasse zählten! Für diese Leistung wurde ihm von der FIDE der internationale Meistertitel verliehen. Nach einigen Jahren als Schachprofi studierte Kaplan Computerwissenschaften in den USA und gründete bald darauf seine Firma Heuristic. Seit 1981 entwickelte Heuristic ausschließlich Schachsoftware für die Firma Saitek. Seine Programme waren von Anfang an hochselektiv angelegt und mit viel strategischem Wissen versehen, die Konkurrenz baute zu dieser Zeit noch ganz auf die Brute-Force-Methode. Alle Kaplan-Programme konnten zwar durch schönes positionelles Spiel gefallen, erhebliche taktische Schwächen trübten jedoch den Spielgenuß. Zur Analyse taktischer Stellungen waren diese Programme nicht zu gebrauchen und konnten sich beim Verbraucher nicht durchsetzen. 1990 beendete Kaplan seine Zusammenarbeit mit der Firma Saitek und nahm mit den renommierten Schachprogrammierern Larry Kaufman und Don Bailey die Arbeit an einem PC-Programm auf. Starke Schachspieler unterstützten die Analyse-und Testarbeit an dem neuen Programm. Die erste Version wurde Heuristic Alpha (Computer) genannt und durfte 1991 beim Harvard Cup, einem Mensch - Computerturnier, mitspielen. Dort errang das Programm einen durchschlagenden Erfolg, denn gleich zwei Großmeister wurden bezwungen und die beste Plazierung aller teilnehmenden Rechner wurde erreicht. In einigen Partien zeigte Heuristic Alpha noch gravierende strategische Schwächen, deshalb hielt Kaplan das Programm vom kommerziellen Markt zurück. Nach einem weiteren Jahr harter Arbeit trat die neue Version unter dem Namen Sokrates wieder beim Harvard Cup 1992 an und errang wieder das beste Ergebnis. Zum erstenmal erreichte ein Computer in einem Turnier ein positives Ergebnis gegen starke Großmeister, das Programm lief auf überall erhältlichen 486ern und nicht auf einer unerschwinglichen Spezialhardware. Leider gab Kaplan auch diese starke Version zum Bedauern aller Schachcomputerfreaks nicht für den kommerziellen Handel frei und arbeitete mit seinem Team konsequent weiter an Verbesserungen. Der nächste Triumph war der souveräne Sieg im Februar 1993 bei der nordamerikanischen Computermeisterschaft, bei der alle Spitzenprogramme und Großrechner vertreten waren, lediglich der Superrechner Cray Blitz (Computer) kam mit einem Remis davon. Endlich wurde dieses Programm mit einer sehr guten Benutzeroberfläche ausgeliefert. Julio Kaplan gehörte zwar mit diesem Programm kurzfristig wieder zu der Spitzengruppe, konnte sich aber in den folgenden Jahren nie mit seinen Programmen in den Top Listen dauerhaft etablieren.

  chancho: The top rated guy in Puerto Rico at the moment is this dude:

Mark Machin Rivera

Jul-31-14  Gallicrow: A few days ago I bought a book by Bronstein on eBay. When I opened it this morning, I discovered to my surprise that it was signed by Bronstein himself: "To my friend Julio Kaplan with best wishes David Bronstein 13.11.1992"
Nov-27-14  Yopo: His most important contribution to opening theory_ probably was: Kavalek vs Kaplan, 1969
Apr-22-15  zanzibar: I think using his full-blown name, even if correct, doesn't correspond to how the player himself wants to be known. I tend to think the name <CG> should use is

<Julio P. Kaplan>

Which is, after all, the name used on both his FIDE card and on the computer wiki page for him:

https://chessprogramming.wikispaces...

He's even published under <Julio Kaplan>:

http://www.schach-computer.info/wik...

What's the source for the full-blown name? That should be included in the bio.

It's quite appropriate to mention the longer name in the bio, but for database use the shorter name <Julio P. Kaplan> should be used, especially since it's the name most often used by the player himself, professionally.

Oh, and did I mention it's the name on his FIDE card?

Mar-28-16  Yopo: Great combination:
J Kaplan vs V Liberzon, 1980
Aug-29-16  technical draw: In the picture Julio looks surprised and is thinking hard. What, he never saw 1.e4 before?

  WannaBe: He was expecting Kp-Kp4
Aug-30-16  technical draw: (WannaBe) I think the correct notation from that time was PK-4.
Aug-09-17  Eagle41257: Yet they write: Julio Kaplan - Puerto Rico, the USA. I've remembered it since my childhood.

  GrahamClayton: Kaplan was a member of the Berkeley Riots team that competed in the US National Chess League in the mid-1970's. The team got their name from the riots that occurred at the University in the late 1960's and early 1970's. Kaplan himself was arrested for taking part in a protest, but was released.
