BTW, Stockfish 130418 is downloaded from chess.ultimaiq.net and I think 130418 is a date of compilation, but original version has been out in 100418:

Simplify condition in space definition

We remove an unnecessary condition in the definition of safe squares
in the space evaluation. Only the squares which are occupied by our
pawns or attacked by our opponent's pawns are now excluded.

STC:
LLR: 2.96 (-2.94,2.94) [-3.00,1.00]
Total: 21096 W: 4321 L: 4199 D: 12576
http://tests.stockfishchess.org/tests/v ... 547e537d4e

LTC:
LLR: 2.96 (-2.94,2.94) [-3.00,1.00]
Total: 23437 W: 3577 L: 3460 D: 16400
http://tests.stockfishchess.org/tests/v ... 547e537d6a

It may be possible to further refine the definition of such safe squares.

Wow, if that is really reliable performance scaling against much stronger engine seems not so great. Roughly 60Elo per time/node doubling. At the level of play of LC0 that is much worse than SF.
