Subject: Implement pondering on position / analysis
X-Git-Tag: 0.18~44
X-Git-Url: http://winboard.nl/cgi-bin?a=commitdiff_plain;h=0547eaa10ec8df7807fceb591c9692c77081afab;hp=023af02b0b3c0643b612183f8670807b081125f4;p=hachu.git

Implement pondering on position / analysis

Pondering is indicated by setting abortFlag to -1. This suppresses testing
on time, both in TerminalCheck() and at the end of an iteration.
