Malus during move ordering for putting pieces en prise
The original idea is the reverse of a previous patch [1] which added bonuses in our move picker to moves escaping threats. In this patch, in addition to bonuses for evading threats, we apply penalties to moves moving to threatened squares.
Further tweaks of that basic idea resulted in this specific version which further increases the penalty of moves moving to squares threatend depending on the piece threatening it. So for example a queen moving to a square attacked by a pawn would receive a larger penalty than a queen moving to square attacked by a rook.
