Chess Daily News from Susan Polgar
I feel bad for Krush. When she had a dead won position, some GM’s in the audience joked that she would lose. And she did . . .
It is unfortunate that Krush lost, but I cannot say that I am surprised. This is a clear example of the problem she has in her game and why she will never ascend to the GM level. The amount of serious time she puts into working on chess is not commensurate with attaining a GM title. It is sad quite honestly because she is a waste of talent.
