Hi,
If you didn't get matched on the Donny lay under 6's, it's not looking hopeful at the moment as its drifted out to 7.4 already with a few hours to go. I would never lay that high, but I'd recommend following the match anyway if it doesn't miraculously move in to 6 or under before the off.
At any stage if Donny go ahead, the odds to lay them will shoot right down somewhere between 2's and 3's if it's relatively early, maybe lower obviously depending on the time of the goal. I'd look to lay them then, as I would always fancy Forest to equalize at least, and then there is your trade off point when/if they do!
This of course depends on if/when Donny score, if it's in the last few minutes, then maybe not! If it's early enough for a comeback, get on the lay at that point as opposed to taking high odds we currently have.
Just some advice. :o)
Cheers
