Worked example

At -110 (standard juice) you need to win 52.38% of the time to break even. At +200 you only need to win 33.3%.

The extra 2.38% is the vig. The book charges it on both sides, so a true coin flip priced at -110 still loses you money long-term.

Find odds priced better than the true probability — that's +EV betting. OddsOps grades every pick against that bar.

Every pick tiered, unit-sized, posted before games — and graded publicly when they end. Wins and losses, on the record, forever.
