I think this is a clear win now. The white king is just too open.  His e-pawn
gets picked off in many lines  and black will still have two reserves!    Like
most endgames,  it's all a question of time. Since  white has to lose a move
to break the  pin and move his king, there is no  point in capturing on b2 yet.
} 50... Kg7 {So Kasparov used his  'extra move' to get his king off the  back
rank and away from queen check and also safe from the white a-pawn  queening
with check.    "The more you look, the  harder it is to find a concrete
winning  line for Kasparov. I'm sure he found that  out himself long ago! Just
pushing the pawn is not enough.  } 51. Ka2 (51. Qb4 Bxb2+ 52. Qxb2 Qe1+ 53. Qb1

Bxb2 52. Qxb2 Qc4+ 53. Ka3 Qxe4 54. a5 g5 55. Qd2 {Watch one trick in these 
endgames. If Black plays his king to g6 and there is a pawn race, white queens
the a-pawn, black  queens the g-pawn, and Qg8+ wins the black queen.    This
is either  winning or it isn't. Computers need evals in order to decide what
to play, so their move  suggestions are interesting. BUT, it is not  relevant
to evaluating the position. There  are many +3 positions that are dead draws
(or theoretical wins) computers don't understand.  } 55... Qf4 56. Qd8 {
Now black catches up in  "queening time" because if the white pawn goes to a7,
Qe3+ puts it back in the box. So white will have to lose  another move with
his queen to protect the  a-pawn.} 56... Qc1+ {Hmm, interesting choice by 
Kasparov. Not sure how the queen can be better on c1 than on f4. Too subtle
for me.} (56... g4 $1 57. a6 g3 58. a7 Qf3+ {
Now the queen covers the h5 square, so there is no perpetual check!} 59. Kb4 g2

So the queen gets back to  the right diagonal with Qe3+ and THEN g4. I  hope!

} 59... Qb3+ {In his infinite wisdom, Garry  decided e3 was better than f4 for
the queen. From e3 it covers the critical a7 square.  } 60. Kc5 {I'm still not
sure if it  really gains a tempo over the immediate  56...g4 line, but I'm
willing to give him  the benefit of the doubt! Mostly I think he  wanted to
make move 60 and get more time.} 60... Qc3+ 61. Kb5 Qb3+ 62. Kc5 Qe3+ {
All those checks were exactly  what the principles of endgame play tell you
NOT  to do! The white king was less active back on a3. But it shouldn't really
matter in this line where the white king is.} 63. Kb4 Qe4+ {f3 was a key
square for the black queen. It eliminated  the perpetual. Now black doesn't
have access to that square with check. From f3, the black queen covered the h5
square, so no perpetual. Now it looks like a draw.  } 64. Kc5 Qc2+ 65. Kb5 Qe2+
