I think my code is self explanatory (probably not...):
/*
* Probe the endgame tablebases
*/
if (ply <= iterationDepth
&& EGTBEnabled
&& PopCount(pos.occupied[WHITE] | pos.occupied[BLACK])
<= EGTBLimit
&& (
Capture(currentMove[ply-1])
|| Promote(currentMove[ply-1])
|| ply < 2
)
)
{
++EGTBProbes;
Score EGTBValue;
if (EGTBProbe(pos,EGTBValue))
{
++EGTBHits;
alpha = EGTBValue;
if (Abs(alpha) > MATE - 300)
{
alpha += (alpha > 0) ? -ply : ply;
}
else if (alpha == 0)
alpha = DRAW;
HashStore(pos,MAX_PLY*ONE_PLY,ply,EXACT,alpha,0);
return(alpha);
}
}
