Date: Fri Feb 26 19:45:29 2021 +0100 Timestamp: 1614365129 Introduce DistanceFromPV We introduce a metric for each internal node in search, called DistanceFromPV. This distance indicated how far the current node is from the principal variation. We then use this distance to search the nodes which are close to the PV a little deeper (up to 4 plies deeper than the PV): this improves the quality of the search at these nodes and bring better updates for the PV during search.

Date: Sat Feb 20 22:49:39 2021 +0100 Timestamp: 1613857779 Introduce ProbCut for check evasions The idea of this patch can be described as follows: if we are in check and the transposition table move is a capture that returns a value far above beta, we can assume that the opponent just blundered a piece by giving check, and we return the transposition table value. This is similar to the usual probCut logic for quiet moves, but with a different threshold.

Date: Thu Feb 18 22:14:55 2021 +0100 Timestamp: 1613682895 Stockfish 13 Official release version of Stockfish 13 Bench: 3766422 ----- It is our pleasure to release Stockfish 13 to chess fans worldwide. As usual, downloads are freely available at https://stockfishchess.org The Stockfish project builds on a thriving community of enthusiasts who contribute their expertise, time, and resources to build a free and open-source chess engine that is robust, widely available, and very strong. We would like to thank them all! The good news first: from now on, our users can expect more frequent high-quality releases of Stockfish! Sadly, this decision has been triggered by the start of sales of the Fat Fritz 2 engine by ChessBase, which is a copy of a very recent development version of Stockfish with minor modifications. We refer to our statement on Fat Fritz 2[1] and a community blog[2] for further information. This version of Stockfish is significantly stronger than any of its predecessors. Stockfish 13 outperforms Stockfish 12 by at least 35 Elo[3]. When playing against a one-year-old Stockfish, it wins 60 times more game pairs than it loses[4]. This release features an NNUE network retrained on billions of positions, much faster network evaluation code, and significantly improved search heuristics, as well as additional evaluation tweaks. In the course of its development, this version has won the superfinals of the TCEC Season 19 and TCEC Season 20. Going forward, the Leela Chess Zero and Stockfish teams will join forces to demonstrate our commitment to open source chess engines and training tools, and open data. We are convinced that our free and open-source chess engines serve the chess community very well. Stay safe and enjoy chess!

Date: Sat Jan 30 13:20:56 2021 +0100 Timestamp: 1612009256 Improve play for closed positions This patch give a small bonus to incite the attacking side to keep more pawns on the board. A consequence of this bonus is that Stockfish will tend to play positions slightly more closed on average than master, especially when it believes that it has an advantage. To lower the risk of blockades where Stockfish start shuffling without progress, we also implement a progressive decrease of the evaluation value with the 50 moves counter (along with the necessary aging of the transposition table to reduce the impact of the Graph History Interaction problem): since the evaluation decreases during shuffling phases, the engine will tend to examine the consequences of pawn breaks faster during the search.
