These games are very beneficial because the theme is very common and the patient winning technique is often beyond players under master level. I know I drew more games than I won in a pawn up late middle game. My plan always being sac the pawn back to attack the King.

Here I wondered why Black didn't play 33....Qxf2, since if 34.Qxb7 Qf4+ 35.Kh1 Qxa4 Black is two pawns up. But then White has the familiar 36.Qc8+ Kh7 37.Qf5+, etc.

I would have been trying to get to a rook ending, but Cramling, being a strong master, had no fear of a queen ending.

A few other SF notes:

White could have played 34.Qg3! since the pawn ending is drawn! Black would have had to avoid the queen exchange, but White would have had much better drawing chances than in the game. E.g. 34....Qxc4? 35.Qb8+ Kh7 36.Qxb7 Qxf2? 37.Qxa6 and White's passed pawn should ensure the draw. I'm sure 34.Qg3 never crossed either player's mind.

After a few other imperceptible-to-me inaccuracies, this position, Black to move, is probably drawn with best play:

But a few moves later, this very similar position, White to move, is a clear win for Black.

Kind of makes me hate engines. I thought 48....Qb4 49.Qxb4 ab 50.a5, etc., amounted to a pawn exchange, but it was actually a transition to a clearly won ending for Black. One of many reasons I'll never be a master.

Couple practice pointers:

Black didn't have to bring her king out towards the end.

Just 59....Qd1+ 60.Kh2 Qb3 61.Qd4 c3, etc. is simpler.
