oh i see this makes sense as far as the matched bet stuff it talks about. So I need there to be someone else out there willing to bet 100 or 100 betters betting 1 unit for me to win 100 if I stake 100? Or does it have to match it to someone who is staking exactly 100 units? So betfair doesn't pay me like TAB does? Its just other punters?

So effectively if I lay bet I don't need to put up anymoney coz I'm the bookie?

Thanks for the rundown King. I don't have an account with betfair just using the guest login to check it all out.
