Two steps slider threats on queen Allow a potential slider threat from a square currently occupied by a harmless attacker, just as the recent "knight on queen" patch. Also from not completely safe squares, use the mobilityArea instead of excluding all pawns for both SlidersOnQueen and KnightOnQueen We now compute the potential sliders threat on queen only if opponent has one queen. Run as SPRT [0,4] since it is some kind of simplification but maybe not clearly one.
