sprt @ 10+0.1 th 1 Adding a few more unsafechecks For example Rg1 Ng4 against h5 Kh8 Ng4 is not in the mobilityArea[WHITE] but should be considered as an unsafecheck. Was already tested here http://tests.stockfishchess.org/tests/view/5a3940ca0ebc590ccbb8bf36 The difference is that I don't allow a bonus for pawn blockers such as White Rg1 g2 against Kg8

sprt @ 10+0.1 th 1 A very interesting patch from nearly three years ago by Vince Negri. Passed STC and long yellow at LTC. Since king safety has been changed drastically since (e.g. it's a quadratic now, we now consider mobility danger, etc.), I think this is worth retesting.

Motivated by loss to A0 here: http://www.chessgames.com/perl/chessgame?gid=1899422, from about move 17-24 SF underestimates White's position perhaps because we penalize White's king too much. Previous versions deleted before it played any games.
