So how's everyone doing with their Bet365 accounts? I thought I'd have a bash at their 2 Up offer. Backed and laid Chelsea, and sure enough, as soon as the score became 2-0 they paid out. So I rushed to Betfair and cashed out my lay bet for £12. QL was £1 so that was an easy £11 profit.
Except... I think I was a bit hasty. The match ended in a draw so if I'd let the lay bet stand it would have won as well. Would've been a £90 profit 
Equally, Chelsea could have won and would have just had the £1 QL, but still!
People on the Oddsmonkey forums talk about "locking in" profit at half time in these situations, but I don't know how it's done. By making some other lay bet?
