OK. Basically who do I use. A quick explanation though. I, with partner, have access to 3 accounts: Bet365, Sky, Betfair. Basically I trawl around the 3 to see who is offering the best price ..... and/or an alleged added benefit. Alleged added benefit tends to mainly when there ia a high priced horse and that bookie is offering extra places. In this case, Sky is the worst of the worst, because they tend to offer lower prices plus hold you to that price; i.e. BOG basically becomes BOG off; a sortof ha ha got yer mate.
Bet365 tends to be the go to, on most days. Not only do they have BOG, but sometimes a flash better odds moment, against which they still aply BOG (One looks to the Sky with disdain). SO there you have it.
Yes Sir! This is always my start point, then with partner check Bet365 first if they are first = on the oddschecker precheck.
