We've all seen a lot of pros do it- have a huge dominant lead and choke to death. Lindsay against Kuznetsova, Maria and Serena. Myskina choked when up 5-1 to Henin. The latest is going on right now in Estoril- Osterloh up 6-0 and a break in the 2nd is now in danger of being ousted. It's incredible how such commanding leads can dissipate. How? Sudden caving in under nervousness? I could understand an injury but in the cases I've mentioned, it just seems to be mental weakness.
