Pion
[ Quark structure of the Pion [1] Pion,
a chess program developed by a group of students from Delft Institute of Technology. Jan Derksen, Harry Nefkens and Jaap van den Herik started the development in 1979, Sito Dekker, Roger Hünen, Gerlach van Beinum and John Huisman joined the team later [2] [3] [4]. Written in the C programming language, Pion had an opening book of 4000 positions in 1983, when it searched about 1K nodes per second [5].
In conjunction with the official name change from Delft Institute of Technology to Delft University of Technology in 1986 [6], Pion was superseded by its successor Dutch (Delft University of Technology Chess Program).
Tournaments
Pion played the first four Dutch Open Computer Chess Championships. The first DOCCC 1981 was the debut, third with 6/9, the DOCCC 1982 fifth with 6/9, the DOCCC 1983 third with 5½/8, and the DOCCC 1984 third again with 4/6. The ACM 1982 in Dallas, Texas was a bit harder, 1 out of 4 running on a VAX 11/780 of Purdue University, the WCCC 1983 in New York on a VAX 11/750 of Bell Laboratories supported by Ken Thompson, and respectable 2 out of 5. Further, Pion played the International Computer Chess Tournament 1984 in Baarn with 2½/5, running on an TNO Geminix [8] with 68000 processor [9].
