Unsafe checks Introducing a new multi-purpose penalty related to King safety, which includes all kind of potential checks (from unsafe or unavailable squares currently occupied by some other piece) This will indirectly detect and reward some pins, discovered checks, and motifs such as square vacation, or rook behind its pawn and aligned with King (example Black Rg8, g7 against Kg1), and penalize some pawn blockers (if they move, it allows a discovered check by the pawn). And since it looks also at protected squares, it detects some potential defense overloading. Finally, the rook contact checks had been removed some time ago. This test will give a small bonus for them, as well as for bishop contact checks.
