Nearly lost £100 matched betting because I put a stake on the wrong market (half time instead of full time). A goal in injury time turned that loss into a £40 profit.
It was this match -
Chelsea 3-2 Shakhtar Donetsk - BBC Sport
I went out for a walk and some beer at half time once I realised I messed up. I needed to clear my head. Betting is stressful. When I came back in I saw the score and I thought I had only lost £5, I was relieved and went to bed. It wasn't until the next day when I checked thoroughly I realised I had made a profit of £40.
A great story I know.
