You go to 5-1 by putting 3000 on USS Tinosa at +100. Then put 2000 on Booklet +140. Booklet wins you win 2800 but lose 3000 hence you lose $200. But if USS Tinosa wins you win 3000 and lose 2000 on the Booklet bet. Hence possibly losing 200 to win 1000. As a general gambling strategy this is also used in Baseball. I also see odds to win offered right now at offshores. One thing I have never been able to do is predict where the odds will end up on horses. Right now the following odds to win are offered at one offshore I like 3 of these in Proud Citizen, USS Tinosa and Table Limit.
