thanks bhagwan.i will put this one in my little black book.
i remember me and a mate watching this bloke in the t.a.b for about 3 months putting heaps on place bets(9 out of 10 he would collect on).so we asked him was he was on about.
he would bet the favorite for a place if there were 3 market gaps between the fav and 2nd favorite.damn clever i thought.
as i recall(and this was 20 years ago)he told us he was making 50pc on t.o.
i cant vouch for the figures as i didnt follow through with any test but it gives one food for thought.
