Hi Macca - I think you still have value with your Henin selection so I personally wouldn't lay the bet off. She's a red hot chance of winning though Petrova won't be as easy as some people think.

My outright on Pierce had more to do with the draw opening up and the chances of her reaching the final after beating Schnyder. If Pierce makes the final I'll let the bet stand if she faces Petrova but will lay back the stake if she faces Henin.
Should be value either way.
