yes, your program (and the others who posted draws) are missing that black is
lost in the line 1...Bb4 2. Kxe2 Qc4+ 3. Qd3 Qxd3+ 4. Kxd3 Bxe7

the point is that the black rook on h8 which you have for the knight is out of
play, and if you do it right, it stays that way. here's a sample line i played
against my fritz in chessbase:

5. h5 {just to make sure that black can't play ...h5 and Rh6, and now black has
many different moves, but i don't believe it makes a difference} 5...Bf6 (Fritz'
choice) 6. Ne6! {freeze! everybody :-)} 6. ...Re8 7. Rb1 Be5 8. Rb6 a5 9. Bd4
{+3 for white now, according to fritzy}

other tries for black may be 6. ...Rb8 7. Bd4 Kxd4 +- or
5. ...Bg5 6. Ne6 Bxe3 7. Nxf8 Kxf8 8. Rf1+ Ke7 9. Rf7+ Kd6 10. Kxe3 with what
looks like a winning rook endgame.

don't believe your programs too much... especially when you see pieces in the
box!
