The sad truth is that part of the top programs do not know much about pawn endgames and some of them can avoid Qe4 only by Deep search. Only Deep search helps Deep Fritz to avoid Qe4 at depth 14. Only Deep search helps Gandalf4.32g to avoid Qe4 at depth 13 and unfortunately it could get only depth 12(Gandalf needs only a few more seconds in Enrique's hardware to find that Qe4 is losing at depth 13 and immediatly it finds a better move. Hiarcs7.32 also likes Qe4 and I guess that only deep search can teach it to change it's mind. Qe4 is a losing move and humans have no problem to see because of the following selective search: Qe4 Qxe4 fxe4 h5 Ka6 h4 Kxa7 g5 Kxb6 g4 a4 h3 when it is clear that the black pawn queens first. Uri
