By 1967, a computer program by Georgy Adelson-Velsky, Vladimir Arlazarov, Alexander Bitman and Anatoly Uskov on the M-2 computer[1] in Alexander Kronrod’s laboratory at the Institute for Theoretical and Experimental Physics had defeated Kotok-McCarthy running on the IBM 7090 at Stanford University.
By 1971, Mikhail Donskoy joined with Arlazarov and Uskov to program its successor on an ICL System 4/70 at the Institute of Control Sciences.
[2][3] In 1972 the program played a correspondence match against readers of popular Russian newspaper, Komsomolskaya Pravda.
Also it could search during the opponent's move, used null-move heuristic and had sophisticated algorithms for time management.
The last time when Kaissa participated in WCCC was its third championship, 1980 in Linz, where it finished tied for sixth to eleventh place in a field of eighteen competitors.
[6] The development of Kaissa was stopped after that due to a decision by Soviet government that the programmer's time was better spent working on practical projects rather than chess.
