Use stronglyProtected ~stronglyProtected is quite similar to ~attackedBy[Them][PAWN] & ~attackedBy2[Them], the only difference appears to be that the former includes squares attacked twice by both sides. The resulting logic is simpler, and the change appears to be at least Elo-neutral at both STC and LTC.
