Merge Gary's king safety tweak Still well within error bars, so probably not a big improvement, but may be worthwhile. I will let the test keep running. The idea for the tweak came from the TCEC game against Houdini. Stockfish saw it as a draw, well past when it should have seen problems. King safety was off, since it was QN and pawns only, but in fact the king was quite vulnerable. After 8000 games at 60/1 (Gary's test) ELO: -0.43 +- 99%: 10.02 95%: 7.62 Wins: 1235 Losses: 1245 Draws: 5520 Total: 8000 PGN of game against houdini. Moves 55-59 it was seeing a draw, and Houdini was seeing a good sized advantage for black. With the change, Stockfish now recognizes that moving the king there is a bad idea.
