![]() ![]() In games played at the slower rate of 40 moves in 40 minutes ( 40/40), Komodo 8 has a 22 elo point lead on Stockfish 5 and a 39 point lead on Houdini. In games played at a rate of 40 moves in 4 minutes ( 40/4), Stockfish 5 leads Komodo 8 by 7 elo points and Houdini 4 by 30 elo points. Komodo 8 appears on two of the CCRL lists.It is in first place on the IPON list, leading Stockfish 5 by 6 elo points and Houdini 4 by 17.Update: The three lists mentioned above have tested Komodo 8. Houdini, Stockfish and Komodo are the three top engines at the moment, with very little differentiating between them, and with the particular order of the engines varying due to time control and other criteria. While many people process private matches, there are three main public rating lists: IPON, CCRL and CEGT. So one way that engines are tested now is in a series of engine vs engine battles. (1) There is little question at this point that the best chess engines of the past five years can beat 99.9% of human players on modern hardware. I put ‘best’ in scare-quotes because there are two ways to look at this question. Which engine is ‘best’ for the practical player to use in his or her studies? Here, however, I want to take up the thorny issue of choosing a chess engine. ChessBase 12 is the gold standard for chess GUIs, and I will be reviewing a new book about proper use of that GUI in the near future. This, as I have previously discussed, involves three elements: the GUI, the data, and the engine. Increasingly I’m convinced that a serious chess player must make use of chess technology to fully harness his or her abilities. Open-source and available at the Stockfish website.
