Hecht didn't give all possible variations but Yace's analyse looks good!
I read it like this: He quickly sees that 1.-b5! is good. Then tries 2.axb5,
finds 3.-Kd8 and sees that black is winning - then changes to look at
2.cxb5 and comes to the same conclusion. I think that Yace would win this
position as black, if the moves given were played out. :)
