The Win Bet Optimizer calculator uses the results of a paper by J.L. Kelly to calculate the optimized win bets when you know an accurate odds-line. Many blackjack experts are familiar with "Kelly optimal betting" which is based on the same paper, and tells you how to bet optimally on a single entry. The Win Bet Optimizer allows you to optimize your bets when you can bet on more than one entry at a time. The bets are optimized as a whole, not one by one.

Tips
You can enter expressions like 15, 3.5, 20-1, 5/2, 8-5, or scr in the odds-line and odds fields.
You can use Tab or Shift-Tab to move from one odds or odds-line field to another.
Be sure to enter the odds-line and odds for all entries. Leaving out an entry will skew the results.
The probabilities are based on the odds-line. If you omit the odds for a scratched entry, the probability for that entry is 0, whether or not that entry has an odds-line.
The optimization occurs only when all indicated bets are made. Making only some of the bets or not betting the indicated amounts produces a return of capital that is less than optimal.
Using an inaccurate odds-line will produce inferior results. You will probably lose in the long run with an inaccurate odds-line.
We have no recommendation for an accurate odds-line. Studies have shown that morning line odds are not accurate.
Even with an accurate odds-line, you can still lose by making the optimized bets.
We make no claim that you will win or that you will not lose if you make the bets in the Win Bet Optimizer.
