If you are re-searching a score from the root that is a mate score
(alpha is > 32000 or alpha is < -32000),
should you turn PVS off?
Has this been looked at before?
Example code:
//Do PVS
if ((foundOne) && (alpha < 32000) && (alpha > -32000)) {
X = -NMSearch(-alpha-1, -alpha, depth+extensions, &line);
//Don't trust a first fail high until it has been researched
// therefore don't use (X < beta) in the below equasion
if ((X > alpha) && (!gAbort))
X = -NMSearch(-beta, -alpha, depth+extensions, &line);
}
else
X = -NMSearch(-beta, -alpha, depth+extensions, &line);
