Stockfish - UCI chess engine,  compiled by  31m059 Timestamp: 1580203885 Less NMP if the position was previously in PV. The intention of the patch is to avoid aggressive null move pruning (NMP)  in positions that have previously been found to be important (PV nodes). If we already do not apply NMP for current PV nodes, it makes sense to apply  it less often for positions that have previously been PV nodes too.

Brainfish - UCI chess engine, CEDR Rating=3262 From the author: Brainfish is a standard Stockfish chess engine extended by a general book format that is capable of handling a reduced part of Cerebellum, which is an innovative chess opening and playing book. In Brainfish, the book moves are only used in engine games, not in analysis mode. All moves in the published book Cerebellum_light.bin generated by Cerebellum were calculated by using Stockfish as analysis engine, without using statistics. Then those moves where recalulated by the Cerebellum Library using a graph algorithm that makes all scores in the library consistant. Consistant scores means for example, in case the starting position has a score of 0.2 and a best move is 1.e4, the position after 1.e4 must have the score -0.2. Additionally, some others properties are found, like the best main line of a position and possible Transitions. Hence, when Brainfish is playing moves that are in the Cerebellum book, it plays lik...

Stockfish - UCI chess engine,  compiled by  Vizvezdenec Timestamp: 1579802605 Tweak trapped rook penalty This patch greatly increases the endgame penalty for having a trapped rook.  Idea was a result of witnessing Stockfish losing some games at CCCC exchanging  pieces in the position with a trapped rook which directly lead to a lost endgame.  This patch should partially fix such behavior making this penalty high even in  deep endgames.

Stockfish - UCI chess engine,  compiled by  Guenther Demetz Timestamp: 1579801427 Use (strict) greater-than-operator for 'improving' Currently on a normal bench run in ~0,7% of cases 'improving' is set to  true although the static eval isn't improving at all, just keeping  equal. It looks like the strict gt-operator is more appropriate here,  since it returns to 'improving' its literal meaning without sideffects.
