Just to clear that up - Im happy to price matches however I'm not comfortable telling people how they should gamble.

What I mean is that Ferrero at 1.28 and Hrbaty at 1.39 are seriously underpriced - even though I mark them as favourites. This leaves you with numerous options:

1) Wait until they get to a better price in the run and back them to win
2) Lay them at the current prices on offer and back them later in the run to cover your losses plus some (assuming their opponents do get close)
3) Back their opponents at the prices on offer and lay them back in the run if they happen get on top
4) Combinations on 2 or 3
5) Lay them at the 3-0 sets option and you win if their opponent takes at least a set

Does that make it a little clearer?
