I've just taken up Netbet offer of a 50% matched bonus on your first deposit. The maximum free bet is £50 requiring a deposit of £100. I've staked my £100 bet and matched it on betfair, with a loss of approx £5, couldn't find any better matching odds. Once the bet has been placed should I aim to try and win the free bet offer on betfair so I don't have to roll over the deposit before withdrawing on Netbet, what is the best way of ensuring that my lay bet is more likely to win on betfair?
