Thanks Chrome, yes I think I am still thinking like a "Bettor" rather than a layer, can't seem to shake it off, but I knew I was on the right track,(no PUN intended) lets just take todays sited example, Ascot race 2 -1 Pre post price = $4, top fluc = 7-1, so lay off initial bet of say $100 on bet fair, say at $5.50 (best price) horse wins so $150 in front, extreme example I know, but remember I will be happy with 1% overall profit (because of the the international benefits, YOU know what I mean)
