Subject: Fix the polling frequency when pondering
X-Git-Url: https://git.sesse.net/?p=stockfish;a=commitdiff_plain;h=e59ff49a55da737a70d2a50fd12d830ae9f22b90

Fix the polling frequency when pondering

When pondering InfiniteSearch == false but myTime == 0 so that
NodesBetweenPolls = 1000 instead of the standard.

The patch fixes the bug and is more robust because checks
directly myTime for a non-zero value, without relying on
an indirect test (InfiniteSearch in this case).

No functional change.
