I am interested because the mate >in 50 is a conversion in one, which is not very long. No, I don't collect that information, that is a whole different database building strategy. I think that all of the long ones in this endgame will feature short conversions, they will be like the case I gave, where white has to underpromote to a knight in order to avoid a drawn KN vs KP. You'd think that in the typical case, you'd be able to move a pawn often in this ending. You see this in other endings as well. In the pawn-up minor piece endings you'll see mates in a hundred or so, because someone has to immediately underpromote into a KNB vs KN. bruce
