I laid the winner on Betfair @ $9.20 and backed it on NSW TAB @ $12.20. When I first looked at NSW, about 10 minutes before race, it was paying $15.50 with $9 million in win pool. I reasoned it could not shorten to $9.20 so I laid it on Betfair , then backed it on TAB.
Easiest money I have made for quite a while, with no risk. Winner was the only runner in race that it was possible to arbitrage with no risk at such a late stage in betting.
