From f9dc502ea66938564e9e6eabcc2aff4199f5dd83 Mon Sep 17 00:00:00 2001 From: H.G. Muller Date: Wed, 5 Dec 2012 16:57:19 +0100 Subject: [PATCH] Fix ponder start There was an inconsistency in starting ponder searches, because they occur with the opposite side-to-move, or thus exchange wtime and btime. This was solved in the old version by changing stm only after starting the ponder search in response to an engine move. But for starting through 'hard' there is no turn change. So the start routine has to swap the times by itself, and the turn change was moved to before it to compensate. --- UCI2WB.c | 11 ++++++----- 1 files changed, 6 insertions(+), 5 deletions(-) diff --git a/UCI2WB.c b/UCI2WB.c index 256150c..029b34b 100644 --- a/UCI2WB.c +++ b/UCI2WB.c @@ -79,9 +79,10 @@ Sync (int action) void StartSearch(char *ponder) { // send the 'go' command to engine.
