LLR: -2.95 (-2.94,2.94) [0.00,4.00]
Total: 15227 W: 3356 L: 3460 D: 8411
sprt @ 10+0.1 th 1 Something about @xoroshiro's Bmob seemed strange to me--I had just tested the exact same tweak to BishopPawns as in that test, and it was -1.5 Elo. Try testing the remainder of @xoroshiro's raw values without this one suspicious tweak.

Total: 14391 W: 3146 L: 3239 D: 8006
sprt @ 10+0.1 th 1 Extend pawn moves such that we are immediately stopped by an enemy pawn, and neither we nor the opponent have pawn breaks available (i.e., there are no pawns on adjacent files which can be pushed to attack).

LLR: -2.96 (-2.94,2.94) [0.50,4.50]
Total: 7344 W: 1510 L: 1638 D: 4196
sprt @ 10+0.1 th 1 Extension for a pawn move that locks up the pawn structure: immediately stopped by enemy pawn and no enemy pawns on adjacent files to attack it. (Fix inconsistent bench: exclude promotions. Trying to find the blocking square above to_sq when to_sq is on RANK_8 created problems.)

Total: 14284 W: 3131 L: 3239 D: 7914
sprt @ 10+0.1 th 1 Revive this tweak by @SFisGOD. It was a LTC 70K yellow on March 10, but probably interacts with the tweaks I made to the kingDanger constant and cutoff on April 9. Does this change the performance of this tweak?

sprt @ 10+0.1 th 1 We recently added an extension for killer advanced pawn pushes for passed pawns. Also extend killer advanced pawn pushes that give check.
19-04-22 31m tweak_BishopPawns^^^ diff
LLR: -2.96 (-2.94,2.94) [0.00,4.00]
Total: 22114 W: 4923 L: 5000 D: 12191
sprt @ 10+0.1 th 1 evaluate.cpp has some small, very Elo-sensitive parameters which can only be tuned effectively by repeated tests (they're too small for SPSA). Since this hasn't been done in a while, and the framework is spending considerable time empty or partially empty, this seems like a potential opportunity for a bit of easy Elo. Start with BishopPawns. MG += 1.

Total: 8398 W: 1806 L: 1929 D: 4663
sprt @ 10+0.1 th 1 Currently, we double an Outpost bonus if the outpost is protected by a pawn. Additionally, +50% Outpost if we can protect it with a pawn push.

LLR: -2.95 (-2.94,2.94) [-3.00,1.00]
Total: 10178 W: 2127 L: 2311 D: 5740
sprt @ 10+0.1 th 1 Does this branch actually produce a worthwhile speedup? Remove it. Non-functional change. (Add "?w=1", no quotes, to the diff's URL to ignore whitespace changes, which are most of the changes in this patch.)

Total: 16101 W: 3546 L: 3631 D: 8924
sprt @ 10+0.1 th 1 Possibly a more precise definition: exclude pawn-defended stoppers. (In that case, the enemy defender recaptures, and our pawn is still not passed.)

sprt @ 10+0.1 th 1 This has produced many promising yellows, but I'm running out of ideas to make it green. Coefficient 2, MG-only quadratic. (Half effect of 61K yellow.)
