Here is a example
Lets say you have worked a race, you have two horses you decide are worth a bet
Again lets deal in reality. You feel both of these horses can and should win the race. but outside of a dead heat only one of them will win, in the real world and this is the key to this post, You feel they both have the
same chance of winning the race
Horse AAA odds are 5/2
Horse BBB odds are 4/1
here is what will happen if you bet 60/40 or 50/50
You bet $100 into the race
Lets say you bet $60 on AAA If it wins, you will get $210
Lets say you bet $40 on BBB It it wins, you will get $200
now its the next race
again your two win contenders are:
CCC at 5/2
DDD at 4/1
You bet $100 into the race but split your bet $50/50
You bet $50 on CCC If it wins you will get $175
You bet $50 on DDD If it wins you will get $250
