c645587270 Simplify semiopen_file (#2165) 
This is a non-functional simplification. Since our file_bb handles either Files or Squares, using Square here removes some code. Not likely any performance difference despite the test.

bf6b647a1a Allow RQ through pieces. Bench: 3415326 (#2153) 
We evaluate defended and unsafe squares for a passed pawn push based on friendly and enemy rooks and queens on the passed pawn's file. Prior to this patch, we further required that these rooks and queens be able to directly attack the passed pawn. However, this restriction appears unnecessary and worth almost exactly 0 Elo at LTC.

The simplified code allows rooks and queens to attack/defend the passed pawn through other pieces of either color.

272936eaba Score and Select Best Thread in same loop (#2125) 
This is a non-functional simplification that combines vote counting and thread selecting in the same loop.

It is possible that the best thread would be updated more frequently than master, but I'm not sure it matters here. Perhaps "mostVotes" is a better name than "bestVote?"

STC (stopped early).
