I don't really have a strong opinion on this and I do know a lot about the game even at a young age. I spoke to someone who has been in the game for 50+ years he said that he used to do $20/$40/$80 you keep backing up your bets but it doesn't work he said.
Now when I think about it I mean if you bet $20/$40/$80 and your horse comes off the board. Now you need your next horse you put $20/$40/$80 on to pay atleast $4.00 for show to just break even from your show bet.
I don't know why people like the $20/$40/$80 method I mean the more money you put on a horse to show it's just like bridge jumping.
Cleary the best bet you can make is Win and Place just incase you get nosed at the wire or bad trip etc. I love doing $150/$50. I really don't think the $100/$100 is good. I think you need to put more money to win and less to place.
IMO the best bet you can make in horse racing is Win/Place. Someone here posted it's about getting winners...I don't agree it's about making money .
1) Win/Place 2) Daily Double 3) Pick 4/Pick 3
Daily Double just could be the best bet because the parlay doesn't pay more then the double.
For example yesterday at Aqueduct Race 1.
$200 to Win horse pays $6.30...So thats $630. Now next horse pays $7.80 si $630 to win on $7.80 would be like $2400ish.
Even with a scratch for consolation which shortens DD payout. It still came back much more...So your $200DD would got you $3600. So it's better to bet DD's then to just keep betting Win each race.
$2 Daily Double (5-8) Paid $36.20 Daily Double Pool $146,342
$2 Consolation Double (5-6) Paid $5.70
