The new Komodo Dragon 3 engine has gained 100 Elo points in playing strength compared to its predecessor when using one processor core in lightning time. A huge step forward for a program that has already performed at an Elo level of over 3500!
The gain is even greater (120 to 130 Elo points) with unbalanced openings, eg rare variants or gambits. When using several cores or longer time controls, however, the Elo increase is somewhat lower due to the higher draw range.

Higher skill level = faster analysis The absolute gain in skill level also offers very practical advantages: Komodo Dragon 3 only takes about a quarter of the time to play or analyze at the same level as Dragon 2! Or he plays better chess on one core than his predecessor on four cores in the same time. The big Elo increase is due to a new network structure for NNUE with a corresponding new network as well as various optimizations and improvements in the search. One for all: freely selectable playing strength between Elo 1 and 3500 Komodo Dragon 3 is delivered with the current program interface from Fritz 18 and thus offers different levels of play. In addition, the playing strength of the engine in Komodo Dragon 3 can be adjusted according to the desired Elo strength from 1 to a maximum of 3500. The Elo values refer to human play in rapid chess and are suitable, for example, to ensure a balanced match. Because when the playing strength is reduced, the engine makes the mistakes that are to be expected from people with the set rating. The Elo settings of Komodo Dragon 3 have been tested and tuned against many human players of all skill levels, particularly in the GM field in numerous rapid chess games against GM Alex Lenderman, who is part of the Komodo development team.
