Why was this a blunder? There are no good moves. What better move did black
have?

43 ... Ke7 44. Qb7+ any 45. Qxb4 winning a pawn
43 ... Kf7 44. Qb7+ Qe7 (to protect the b pawn) 45. Qxe7 and black's king is
even further back than with what was played
43 ... Kf4 44. Qf3+ Kg3 45. Qg4+ any 46. Qxb4
43 ... Kf4 44. Qf3+ Kg4 45. h4+ Kg3 46. Qg4+ any 47. Qxb4
43 ... Kf4 44. Qf3+ Kg4 45. h4+ Kh3 46. g4 and black cannot take the b pawn or
47. Qf4+ Kg3 48. h5++ or Kh4 48. Qg5++
43 ... Kg4 44. h4+ and a variety of other moves which lead to the same capturing
of the b pawn or mate with the same themes as above

And eventually, no matter how black plays, once white wins the b pawn, all white
has to do is place the queen on b7 and push the b pawn. If black tries to check
white first, white plays Kh3, interposes his queen on any other check, puts his
king back on g2, eventually plays Qf3, and can push b3 to protect the b pawn. It
will be REAL hard for black to prevent white from trading queens and having a
passed pawn.

This seems lost no matter what, so how exactly did black blunder here? Not
trading queens does not delay the inevitable much, if at all.
