At the 5th Computer Chess World Championship (5th WCCC) in Cologne in 1986, 23 programs competed against each other. One of them was Lachex . Its two developers used “the largest computer in the world at the time”. It was a Cray XMP 4/16 (picture) , of which they usually only had a small part of the computing time available during the World Cup.
At the 17th North American Computer Chess Championship (NACCC) in 1986 in Dallas , Lachex took second place behind the tournament winner Belle . The game of Lachex and Bebe at this tournament gave rise to the formulation of the idea of singular extensions .
