Agree especially if the underdog scores early .If you were willing to take 1/2 about a team to win you were not expecting them to win by 1 goal so if they go 1 down and you can get 15/8 9/4 its a fair bet .When the equalize take a bit of profit .
No, I would not take the profit if they equalize, I would hold fer the final result, the thinking being that once the bigger team are back in play proper it's only a matter of time before they annihilate their weaker opponents.
I think the theory is sound but the time and effort to do it is not fer me as it would have to be done properly and not just when I feel like it.
Handicap betting is different as in again take Liverpool last night, if they had been ahead after 90 minutes then no way would they have scored that last ditch goal in injury time fer the 3 points.
So buy backing a team -1 goal if the score is 2-1 in their favour with a few minutes to go they will not be pushing fer another goal, but back them to win the match when a goal down and then they will play.
