It seems that you are right that it is a draw but proving it is not so simple. The king cannot be always at f2 f3 because when it is in f3 after Be3 Qf1+ Bf2 Qh1+(or Qd1+) it must leave the f2-f3 area. In order to prove a draw we need a table of the white pieces against every possible position of the black pieces(including positions without one of the black pawns). I also think that in comp-comp games it may be not a draw because white may blunder(for example by prefering gxh4 and not Rxh4 that gives black chances thanks for the passed pawn) Uri
