To top the rating lists and get more interesting middle play, it is a good habit to set the default contempt to the highest value that does not regress against contempt=0. We recently decreased PawnValueEg it is logical that to raise a little bit the default higher contempt because of the following internal dependency in line 334 of search.cpp : ```` int ct = int(Options["Contempt"]) * PawnValueEg / 100; // From centipawns ```` STC: contempt=24 passed non-regression vs contempt=0 http://tests.stockfishchess.org/tests/view/5bd6d7f80ebc595e0ae21e14 LTC: contempt=24 passed non-regression LTC vs contempt=0 http://tests.stockfishchess.org/tests/view/5bd6e0980ebc595e0ae21f07 On 2018-11-01, we also tested the effects of contempt=21 and contempt=24 against Stockfish 9, and the net result was neutral: Contempt 21 ELO: 51.68 +-1.9 (95%) LOS: 100.0% Total: 40000 W: 9487 L: 3581 D: 26932 http://tests.stockfishchess.org/tests/view/5bdb1a140ebc595e0ae2620a Contempt 24 ELO: 52.21 +-2.0 (95%) LOS: 100.0% Total: 40000 W: 9759 L: 3793 D: 26448 http://tests.stockfishchess.org/tests/view/5bdb1b680ebc595e0ae2620d Bench: 3459874
