Simplify ThreatBySafePawn evaluation Simplify ThreatBySafePawn evaluation by removing the 'if (weak)' speed optimization check from threats evaluation. This is a non functional change as it removes just a speed optimization conditional which was probably useful before but does no longer provide benefits. This section section had a few more lines not long ago, with ThreatByHangingPawn and a loop through the threatened pieces, but now there is not much left. Passed STC: LLR: 2.95 (-2.94,2.94) [-3.00,1.00] Total: 47775 W: 9696 L: 9624 D: 28455 http://tests.stockfishchess.org/tests/view/5ac298910ebc591746423f8b Closes https://github.com/official-stockfish/Stockfish/pull/1531 Non functional change.
