In addition to ranking chess engines from best to worst, these lists also provide margins of errors on the given ratings.Īmong these rating lists, the most famous are CCRL (Computer Chess Rating Lists) and CEGT (Chess Engines Grand Tournament). There are literally hundreds of ‘rating lists’ that measure the relative strength of chess engines, based on how many moves they make per minute. These numbers are dwarfed by the number of possible moves in chess, making it one of the most complex board games. To put this into perspective, there have been only 10 26 nanoseconds since the Big Bang and about 10 75 atoms in the entire universe. If you construct a complete tree of all possible moves in a chessboard, you will get a total of 10 120 moves.

Modern engines are more selective and have a better positional understanding. Since the hardware and programming techniques are getting better year by year, chess engines are becoming more intelligent.

A chess engine usually analyzes thousands of outcomes before making an efficient move.
