Partypooper,

As Shy has indicated the price on Betfair is usually over the TAB/Bookie price so simply laying what you used to back will generally not work to well (of course it depends on how much of a loss you are making to start with - if you are loosing 30% on turnover then you probably could make a decent profit simply laying your selections). I have been working on a system for laying and here are the selections for today.

The rules are simple - if the horse is over $4 on Supertab (but less than say $12 - don't want the risk to be too high) then lay it on Betfair provided the price is not too much higher than the TAB price (10-20% should be OK). If it is under $4 on TAB AND the price on Betfair is higher than TAB then back the selection instead. I have given 2 selections for each race - only use the 2nd one if first selection is scratched.

SR1 1,5
SR3 1,4
MR3 1,3
SR4 5,7
SR5 1,11
MR5 2,6
SR6 6,1
MR6 2,15
SR7 2,3
SR8 2,5
SR9 7,3
MR9 1,2
