Lock it, swing it, or scoop both.

Three things should be true: there’s a clean opposite bet available, your original odds have improved so the math works, and you either get a good number on the hedge or you’re happy to trade a little long-run value for certainty tonight. If none of those hold, letting it ride is usually the higher-EV play.

Be honest with yourself here. A lock (equal-profit) hedge does guarantee the same profit either way — but because the book charges vig on both sides, you’re usually paying a small slice of expected value for that certainty. The only true free lunch is an arbitrage or a “free middle,” where the prices are soft enough that every outcome profits. Those are real but rarer, and books limit accounts that hammer them.

A middle is when you hedge at a different number than your original bet, opening a window where both tickets win. Example: you hold Cowboys +7 and hedge Eagles −3. If the Eagles win by 4, 5, or 6, your +7 covers and your −3 covers — you scoop both. Outside the window you’re still protected; inside it, you hit the jackpot.

The trap version. If your numbers are set the wrong way — you lay more on the hedge than your leg is getting — there’s a gap where both bets lose instead of both winning. Always check which way the window runs first. The calculator turns red and warns you when a middle is inverted; almost no other tool does.

Most books let you move a spread or total by a half or full point for extra juice. Buying a point can widen your middle window — or even turn a middle that costs you a little into a guaranteed one. The calculator shows exactly which point to buy, what it adds, and roughly what it costs.

Both lock in a result, but the sportsbook’s cash-out button is built to favor the book — it almost always pays less than hedging yourself. Drop the cash-out offer into the calculator: if the hedge pays more (it usually does), skip the buyout and place the hedge.

Let it ride — no hedge, full payout or nothing.
Minimize loss — you’re underwater; lay to cap the damage.
Free-roll — lay just enough to win your stake back, leaving a free shot at the middle.
Lock a profit — guarantee the same green either way.
Swing the middle — light hedge, keep most of the upside and a fat shot at both cashing.

You usually need two different bets, often at two books, windows can be small, and lines move fast — so act quickly and double-check your numbers. Books also limit or ban accounts that middle and arb aggressively, so spread your action around. And never hedge on emotion: run the math first.

Shop every book for the opposite side — even −145 vs −150 changes your lock. The best hedge price is often at a different book than the one holding your original bet.
