LOL WTF do i know.....Cheylesmore hacks up at nearly double the price I bet!!!!
When the price drifts out from the one you've taken do you press up the bet as its now even bigger than your "value" odds?
I'm gona field this one too coz its an interesting one.
In the past this was definitely the +ev thing to do but nowadays the market (largely coz of the exchanges and technological advances) is too wise to make it worthwhile in the long term. Now I think the opposite in a way is almost worth doing, when you fancy a horse and its price is contracting to get further and further involved if you still think its somewhere near reasonable value.
In Championship Football I'll still do it because I'll believe I'm right and the market is wrong at times (for example when Derby drifted out from 2.6 to 3.8 at home a few weeks ago which I thought was massively wrong with the market over-reacting on a huge scale to Millwall's new signings and general ability) just because you can have the confidence that you have pretty much all the information available to you that you need to have to judge the market correctly.
In racing you often don't know things like how the horse is behaving at the track, if all is well with the horse/stable at home and many other factors.
