Strategy - exchange poker?!

i've been with betfair for at least 2 - 3 years now, i started out with just goals then betting on next goal, this won me some money and was happy with everything i achieved/won . . . but i got bored when there was no football on. so i delved into exchange games, i started with hi-lo backing constantly on a 2 card win. this was good to me for a whole 2 months or so then when i started losing, i chased and obviously lost. this is when i realized the awesome (and of course winning) way of laying. this is where i sat and watched poker turbo for an hour or so and i realized that only 2 -3 times did the last winning hand win again on the next hand. i had a brain wave . . i just laid the hand which had just won. you have to wait a while for the hand to win twice in a row but soon as it comes get laying and i'd say don't lay a price of over £20. once you've won 5 times, come off for a few hours or be happy with your winnings. this can be cruel but when you hit the streak . . . let the good times role!
