IE the current candidate passer detection easily finds that with white pawns on a2/b2/c2, black pawns on a7/b7, that it has a candidate passer/candidate outside passer. But it also knows that moving the black pawn to b6 disrupts this totally and requires white to sac a pawn to get a passer, but giving black one as well (the pawn race will at least make it do this in the right cases however.) The real issue is overall pawn structure. In the middlegame I would rather have a7/b7 for black. In that endgame, I would rather have b6/b7... it seems a bit messy to handle properly... even though the code for detecting the candidate passer was easy... using the information is not so easy...
