Small reformat in evaluate threats (non functional) When evaluating threat by safe pawn and pawn push the same expression is used. STC LLR: 2.95 (-2.94,2.94) [0.00,5.00] Total: 19444 W: 4540 L: 4309 D: 10595 Closes No functional change. -------------------- Comments by St├ęphane Nicolet: I don't measure any speed-up on my system, with two parallel benches at depth 22: Total time (ms) : 74989 Nodes searched : 144830258 Nodes/second : 1931353 master Total time (ms) : 75341 Nodes searched : 144830258 Nodes/second : 1922329 testedpatch And anyway, like Stefan Geschwentner, I don't think that a 0.3% speed-up would be enough to pass a [0..5] LTC test -- as a first approximation, we have this rule of thumb that 1% speed-up gives about 1 Elo point. However, considering the facts that the reformatting by itself is interesting, that this is your first green test and that you played by the rules by running the SPRT[0..5] test before opening the pull request, I will commit the change. I will only take the liberty to change the occurrences of safe in lines 590 and 591 to b, to make the code more similar to lines 584 and 585. So approved, and congrats :-)
