MWP, we’ve discussed this before. You can make “zero-hold” bets on both sides of an event (like -300/+300) at zero cost to you. So, the value of the free bet becomes your EV. These odds combos are relatively easy to find with an odds finder service like OddsJam. Without that, not so much. However, you can get close. Most of these odds combos are found in alternate lines (spreads/totals). So, you could search “alternate lines” on an event in Caesars and then dig around somewhere else (DK, FD, etc) for the opposing side. To minimize your loss, your $100 you bet on Caesars should have the most negative odds. So, bet the $100 on the Caesars side and then do some easy math to figure out how much to bet on the other side to break as even as possible. Quick tip is that the TOTAL (wager plus winnings) should be equal for both sides. If you want to go for Diamond on Caesars, then do this 260 more times before the end of the year .
