I know he's a thoroughly dislikeable individual, but I think Mervyn King may be the only one to give Taylor a match on that side of the draw.
Kevin Painter and Ronnie Baxter would be the two I'd be looking at on the other side of the draw at the prices. Painter usually goes well at the World Championship and he isn't likely to throw the towel in like that clown Mardle last night. Baxter was in great form earlier on in the year, he might have slipped back a bit since Vegas but if he can get a bit of momentum going he could go far.
BTW, how did this Kirk Sheppard lad reach the final a few years back? I'd give him a run for his money down the local!
