Matches that affected the players for the rest of their careers
The first one that comes to mind is the '93 FO QF Gaby lost to Mary Joe. It was just painful the way she let the huge lead slip and ended up losing. From then on, Gaby had a looong title drought until she finally won the YEC in '94. She went nearly two years without winning a title.. that was crazy for a player as consistent as Gaby up to that point.
I'm positive that match affected the rest of her career and had she won it, then she would have gotten some more GS titles under her belt.
I would like to know what you guys think of the infamous 93 Wimby Final. Do you think that match would have changed Jana's life as a whole if she hadn't choked it away? It was a huge relief that she after won it in the twilight stage of her career. I was very happy for her after choking twice big time!
