IE what if there is only one way out, and you don't follow it. Do you use the resulting (and wrong) mate-in-N score? What if there are two ways out, one that draws, one that loses a knight. What do you do if you fail to follow the one that draws and assume you lose a knight? You should not do all evasions if the moving side has any stand-pat opportunity of course, as he would always choose to stand pat rather than getting mated, which would be a wrong score backed up. But if you are at an even ply, and you were in check at _every_ q-search node for even plies, then forcing all replies here makes good sense as if you find it is mate, it is forced. It won't necessarily be the shortest mate, but it will definitely be mate.
