Tommorrow at Epsom Downs, Coronation Cup?

Can the filly Midday beat St Nicholas Abbey? I watched St Nicholas Abbey do a demolition job at Chester a few weeks ago, very impressive, but nothing in the field to compare with the mare Midday. Both are genuine Group 1 animals. On the otherhand Midday is racing against a colt this time, with only a 3lb pull. I`ve been watching replays, and racking my brain, but I can`t split them. What do you think?
