White is forced to move its pawns forward until black will have all eaten them and then has to move its king which looses. This is another one of Eduards famous zugzwang-problems which are for most engines very hard. Congratulations! P.S.: Play 1.b4 Kb7 and even Shredder will realize that white is lost ;-)
