sprt @ 10+0.1 th 1 Adding middlegame components to these scores has shown promise in the past, but has never been quite enough to pass. Respin with effect sizes that are larger and unequal between the two cases (minors and rooks).

Total: 22405 W: 5056 L: 5109 D: 12240
sprt @ 10+0.1 th 1 @sg had several promising passed pawn patches recently (changing bb and/or k) which didn't scale to LTC. Now that PR #2182 cleans this part of the code up a bit, see if they are now able to pass.

LLR: -2.94 (-2.94,2.94) [0.50,4.50]
Total: 12150 W: 2655 L: 2759 D: 6736
sprt @ 10+0.1 th 1 Building on @Vizvezdenec's best take (#3). I hypothesize it is good to have queen and bishop on matching-color squares in the middlegame, to coordinate attack, but bad in the endgame, where we want to cover as many squares as possible.

Total: 31142 W: 5218 L: 5272 D: 20652

LLR: -2.96 (-2.94,2.94) [0.50,4.50]
Total: 34078 W: 7635 L: 7630 D: 18813
sprt @ 10+0.1 th 1 Take 3: A refined version of take 2, based on a case pointed out by @Lolligerhans, where the neighboring pawn is advanced and able to threaten a faraway stopper. Consider the pawn able to push in this case.

Total: 24787 W: 5536 L: 5577 D: 13674
sprt @ 10+0.1 th 1 Take 2: don't count enemy pawn attacks. Only consider stoppers on the same file.
19-06-02 31m Outpost_pushablePawn diff
LLR: -2.95 (-2.94,2.94) [0.50,4.50]
Total: 12581 W: 2741 L: 2843 D: 6997
sprt @ 10+0.1 th 1 My attempt at a much lighter-weight version of @Lolligerhans's idea. Exclude from the outpost calculation pawn attacks from pawns with no hope of pushing: if a pawn has stoppers and no neighbors beside or behind it, only include pushes up to its stopper.
19-06-02 31m initatk1 diff
LLR: -2.95 (-2.94,2.94) [0.50,4.50]

sprt @ 10+0.1 th 1 Endgame penalty S(0, -16) if our threats against enemy pieces are offset by an active bishop--increasing penalty for the more pieces this bishop is defending. (Effectively this is like an endgame-only Overload penalty, but of opposite effect.)
