Kibitzer's Corner
Oct-26-04  Knight13: Since Chess 4 drawed in 1774, Chess 4 has fight back. Too hard to be beaten in the 1970's. Good game.

  RandomVisitor: Botvinnik writes of this game in Computers in Chess: Solving Inexact Search Problems:

"KAISSA used a computer with a speed of 3 [million] operations per second, CHESS 4.6 had a speed of 12 [million] operations per second. KAISSA could calculate variations to a depth of 5 plies; CHESS 4.6 could go to 6... In the end [game], KAISSA extended the length of a variation to nine plies and CHESS 4.6 went to twelve."
