In the year 1997, IBM's Deep Blue defeated the world chess champion Gary Kasparov. Because standard chess game results in ten to the power of 125 possible board positions in the look-ahead tree, it takes ten to the power of 108 years if the computer can calculate one billion moves per second to examine these board positions. Deep Blue evaluated 200 million moves every second.
The computer architecture of Deep Blue is a highly parallel architecture with 32 nodes and 512 ASICs to encode move generation. Each node contains IBM Power2 Super chip, which executes 6 instructions per cycle.
