The original El Ajedrecista by Leonardo Torres y Quevedo was an exhibit in the tournament hall [1] . The Seventh World Computer Chess Championship was a triumph for the RISC architecture - Ed Schröder won the title with the TASC Chessmachine [2] , with a program called Gideon, a port of his Rebel program for an ARM2 RISC Processor, plugged as ISA card into an IBM PC. Runner up Zugzwang played with a grid of 1024 Inmos T800 Transputer [3] . With Kasparov Sparc, under the patronage of Saitek, Kathe and Dan Spracklen played their last tournament, after losing the finish against the Chessmachine. Berliner's HiTech used B*.

Wedgitude, then, by a well-known English transformation, is the state of being wedged".
