The passed danger and close enemies values seems the most sensitive (changing close enemies alone to 6 failed before but now it passes), whether or not they are close to optimal I don't know, but it seems some parameters are also correlated to others.

Date: Fri Jul 6 01:34:01 2018 +0200 Timestamp: 1530833641 Simplify ThreatByKing to be a single Score. In the current master, ThreatByKing is an array of two Scores, one for when we have a single attack and one for when we have many. The latter case is very rarely called during bench and was recently given a strange negative value during a tuning run, as pointed out by @candirufish on commit efd4ca2. Here, we simplify away this second case entirely, and increase the remaining ThreatByKing to compensate. Although I derived the parameter tweak independently, with the goal of preserving the same average bonus, I later noticed that a very similar Score had already been derived by an ongoing SPSA tuning session. I therefore recognize @candirufish for first discovering these values. I would also like to thank @Rocky640 for valuable feedback that pointed me in the direction of ThreatByKing.

Date: Tue Jun 26 09:08:15 2018 +0200 Timestamp: 1529996895 Remove make_bitboard() In current master, the function make_bitboard() does nothing apart from helping initialize the SquareBB[] array. This seems like an unnecessary abstraction layer. The advantage of make_bitboard() is we can define a bitboard, in a simple and general way, not only from a single square but also from a list of squares. It is more elegant, faster and readable than combining multiple SquareBB explicitly, but the last complex use case in evaluation was simplified away a few months ago. If make_bitboard() becomes useful again to define complicated bitboards, it will be easy enough to reintroduce it using this pull request as an implementation reference.

For example a White rook on a1 attacking a black pawn on a7 would score the bonus * 6 but would be probably better placed on a8 b) a defender might be counted on different pawn paths and might be overloaded. For example a Ke4 or Qe4 against pawns on d6 and f6 would score the bonus * 6. Counting each blocker or attacker only once is more complicated, and does not help either: http://tests.stockfishchess.org/tests/view/5b2ff1cb0ebc5902b2e582b2 After this small simplification, there might be ways to increase the HinderPassedPawn penalty.

There was a bunch of patches that passed recently regarding captures, maybe this part of the master code redundant? The patch was tested as a simplification: STC: LLR: 2.95 (-2.94,2.94) [-3.00,1.00] Total: 20833 W: 4218 L: 4096 D: 12519 Elo +2.03 http://tests.stockfishchess.org/tests/view/5b1cf2100ebc5902ab9c6651 LTC: LLR: 2.95 (-2.94,2.94) [-3.00,1.00] Total: 27050 W: 3975 L: 3864 D: 19211 Elo +1.43 http://tests.stockfishchess.org/tests/view/5b1cfdc80ebc5902ab9c6776 Closes https://github.com/official-stockfish/Stockfish/pull/1643 Bench: 4980482 see source |

Date: Mon Jun 11 09:54:32 2018 +0200 Timestamp: 1528703672 Optimize contempt value (21) After several tests it seems best to increase contempt from 12 to 21. This does not regress against contempt=0 and gives a gain of around 7-8 elo against SF 7 in comparison to current default contempt.
