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.

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!

Now the queen covers the h5 square, so there is no perpetual check! 59.Kb4

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.

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.

A ChessBase program with tablebases will now happily inform you that this position is mate in 62! But that would almost certainly be harder for Black to win than the queen endgame with two black pawns. 73...Qg5+
