In Play Betting Rugby Leauge
If you lay the fav at short prices and wait then bet back in play you can have your money running for nothing. eg Wests lay @ 1.5 and back @ 5 on Betfair. You need to ring to back in play.
Yeah, you can make some easy money, I've be looking more into greenbooking and trading rather than just back something outright, even if there only small profits, better than a loss and they all add up. I find calling up in play so annoying, really I don't know why its not legal yet (anyone know if this is happening soon) or alternatvely after your laid it you can put it how much you want to back it at and keep it in play,
I think you can lock inplay in Bettrader and on Betfair Don't know I just ring up
