From a66a7c3870d7b88054d0d6b7c7f734a60fab27f4 Mon Sep 17 00:00:00 2001 From: Marco Costalba Date: Sun, 13 Jan 2013 14:28:22 +0100 Subject: [PATCH] Small change to "ponderhit" handling Reset Limits.ponder only if search continue, but if we are going to stop the search there is no need (and is also confusing) to clear the 'ponder' flag. This mimics the behaviour upon rceiving 'stop' when pondering. No functional change. --- src/uci.cpp | 12 +++++++----- 1 file changed, 7 insertions(+), 5 deletions(-) diff --git a/src/uci.cpp b/src/uci.cpp index 49a0b22f..ddaad417 100644 --- a/src/uci.cpp +++ b/src/uci.cpp @@ -73,16 +73,18 @@ void UCI::loop(const string& args) { } else if (token == "ponderhit") { - // The opponent has played the expected move.
