The bread and butter is what you have probably done with those two...
1. Place a back bet with a bookie.
2. Place a corresponding lay bet with an exchange, taking a small loss.
3. Receive a free bet that you turn into guaranteed cash by doing another back/lay at likely longer odds.
Sometimes you do the initial back/lay in the hope of triggering a free bet, as opposed to one being guaranteed.
What you'll find is that you have a pot of money that basically gets swirled around between different bookies and exchange(s) and the size of that pot will gradually grow.
So when a match is 100% or above, you basically cannot lose? As your back and lay bets are such that you would be in profit, I'm getting that right?
Smarkets against betfair there are currently a couple of matches at 133% and 121%. Seems too easy!
