A little news for fans of chess engines, especially those of you who may have bought a one-year subscription to the Komodo chess engine: version 10.3 is out, and the claim is that it's 30 points stronger than 10.2. Komodo 10.2 was itself stronger than the 10.1 release that narrowly missed the TCEC Superfinal, so don't reject it on that basis. (Of course, the TCEC champ, Stockfish, is always available for free, but different engines have different strengths, and one isn't always right vis-a-vis its rivals.)
