From: Joona Kiiski Date: Sun, 15 Sep 2013 19:54:26 +0000 (+0200) Subject: Fix time parameters for blitz games X-Git-Url: https://git.sesse.net/?p=stockfish;a=commitdiff_plain;h=77b5ee0117e86736817cf90f64055dce1ddbc55e Fix time parameters for blitz games The ideal setting for super-blitz might be something like: "Emergency Base Time" = 50 "Emergency Move Time" = 5 This would give a total emergency time buffer of: 50 + 40 * 5 = 250 ms This setup replaces the previous half cooked hack "Don't blunder under extreme time pressure". Test results are very good at super blitz, but keep good even at 60 secs.
