Darky,

Here's a golden oldie for ya,see if ya can guess what it is!

Rule 1)Eliminate any race where the fav is odds on PP
Rule2)Mark all horses which have raced in the last 9 days(inclusive)
Rule3)Horse must be selected in the most favoured column(must be at least 8 tipsters)
Rule4)Must have placed 1,2,3 at ONE of it's last 2 starts,and if a placing only,must have finished within 3 lengths of the winner.
Rule5)Had 7 career starts,unless 2 or 3YO,then 5 starts.
2 and 3Yo against older horses 7 starts.
Rule6)Has had 2 starts this prep,and has not won it's last 3 starts.
Rule7)Eliminate Maidens an Jumps,and jumpers runnung in flat races.
Rule8)Last start winner must not be going up in weight more than 1and a 1/2 kilos or down in weight more than 5&1/2 kilos from last start(after deducting any apprentice allowance)
Rule9)If there are 3 selections for any one race,bypass that race.
If there are 2 selections,the bet is the horse which is better off at the weights compared to last start,UNLESS
a)both have the same weight difference or there is only 1/2 kilo between them
b)both raced in a set weights feature race and today's race is similar
c)one of the horses is down in class
If either a,b,or c apply,the bet is the longer priced of the 2 in the prepost market.
When there are more than 5 selections at a single meeting,eliminate any runners less than 5/2 PP.

There are also a set of Super Select rules,but I'm sick of typing right now.If your'e interested I'll post 'em later on.
