I do not say always evaluate them as unclear but only evaluate part of them as unclear. There are cases when you can be 99% sure that unstoppable passed pawn wins(for example when the opponent most advanced pawn is less advanced and the question what to do when it does not happen. unclear also does not mean exactly 0 and may be something between -1.xx and +1.xx It may be dependent on how much the opponent pawns are advanced and how much the opponent king is advanced. In the relevant case black pawns are more advanced than the unstoppable white pawn and I am not sure what happens in most of these positions. Uri
