Heres another idea that seems to work OK.

Target the tipsters 1st selection in race No.1 we dont bet on this.
If it gets a place .
Bet the tipsters 1st selection in race No.2 for the Place ,
if its paying $1.30+ for the place.

If the tipsters horse in race No.1 falls over , no-bet in race No.2

Now look for a tipster that may have struck a Place for the 1st selection in race No.1 then bet their 1st selection in the 2nd race.

Plonk $20 on for the Place.

This seems to have a very high SR for some reason.
Check it out on some past results first.

Cheers.
