lol vads, with all due respect, you worked on the gate, not in the stewards or presidents rooms, or stables, or stipes room, and you probably weren't someone that those 'in the know' really cared to pass proper information aka 'good oil' on to.

Oh and I WAS a steward

Anyway, Its the entertainment dollar, like betting on sports results or even poker.
And like those, only the few become - and succeed - as professionals.
I'm an 'enthusiast' and am happy to share my 'knowledge' with my fellow biggie gamblers to spread the gospel of the horse

So here's an example of how I operate:
I had a $2600 collect on Friday night, after putting $100 in my phone account. I top up my account with anywhere between $50 and $150 once or twice a week, depending on whats on and how busy I am. I spend most Mondays driving around the 3 Queenstown TABs to see if any of them have enough money to pay me out

I like to study form properly and have built up a good pool of knowledge with regards to racing patterns, horse breeds, ages, conformation, distances, trainers, jockeys, owners, tracks conditions & biases, which races to bet on/which to avoid, horse preperations and even the odd 'gut feeling'. So much other shit as well which I cant think of right now. Of course often im wrong, thats racing. But generally my selections are fairly close to the mark.
Consider the above collect on Friday night, courtesy of race 4 at the big Auckland Harness meeting. There was a huge first 4 pool, courtesy of it being a big race night with aussie interest (they can bet into our pools and vice versa). An ideal race to spent $10 on a first 4 bet.
I took the favourite and 5th favourite to run first and second (I know the trainers of both and like the way they've been running, their draws, times etc etc) then a bunch of other horses to run 3rd and 4th which I selected for various reasons including offering juicy odds that would bolster my collect... The end result: favourite won, 5th fav 2nd and the 2 outsiders of my 'behind' horses came in 3rd & 4th. Dividend $12000, of which I had about 22% of for my $10 investment. BOOM.
It aint that hard or rare, you just have to know what you're doing and have a wee bit of luck on your side. Dont go silly betting on everything all the time, or blowing your winnings on big stupid bets and you'll probably come out on the right side of the ledger
