How does Positive Expected Value (EV) betting work?

When bookmakers set betting lines, they estimate the likelihood of each outcome.

Value Bets, our Positive EV Tool available for Oddschecker+ subscribers, leverages advanced AI to perform 100 million projections each week and monitors 125 million live price changes daily. This enables it to identify bets that have a higher probability of winning than what the lines suggest.

Shown below are our five best player props from the Positive Expected Value tool for Thursday October 30th's NBA slate.

Tip 1: Victor Wembanyama - Under 3.5 Assists vs Miami Heat - 1pt

Victor Wembanyama is trending toward staying below this assists line as the Spurs' focal point emphasizes scoring and rebounding over facilitation, where he's averaged 2.8 dimes through four early games with outputs of 1, 2, 4, and 4, dipping under 3.5 in half his outings while prioritizing elite production elsewhere (31.0 PPG, 13.8 RPG).

Miami's defense against centers allows 5.05 assists in small-sample data, but Wembanyama's low-volume passing role (echoing a 3.4 career average) and the Heat's mid-tier perimeter containment could suppress secondary creation, especially in a matchup projecting conservative play-calling for San Antonio's young core.

Our Positive EV tool has the probability of this bet landing at 69.33%, so the odds of 11/10 with Ladbrokes/Coral give us a Positive EV of 45.59% on this play. 

Golden State Warriors @ Milwaukee Bucks

Tip 2: Brandin Podziemski - Over 1.5 Threes vs Milwaukee Bucks

Podziemski has been a reliable perimeter threat for the Warriors, knocking down 2.0 threes per game on 5.0 attempts at a solid 40.0% clip through his first five appearances.

His recent form—hitting 3, 1, 2, 2, and 2 threes—demonstrates steady volume in 28.4 minutes per outing, fitting seamlessly into Golden State's high-octane offense that ranks in the top five for three-point attempts league-wide.

The Bucks' defense, while stout inside, has been average on the perimeter, surrendering 12.5 threes per game overall and specifically 3.0 to opposing shooting guards in early-season data.

With Milwaukee potentially shorthanded (Kevin Porter Jr. out with an ankle injury), Podziemski's spot-up opportunities could increase, making this over a strong play.

Our Positive EV tool has the probability of this bet landing at 78.5%, so the odds of 17/20 with Ladbrokes/Coral give us a Positive EV of 45.23% on this play. 

Miami Heat @ San Antonio Spurs

Tip 3: Harrison Barnes - Over 1.5 Threes vs Miami Heat

Veteran forward Harrison Barnes is finding his rhythm from beyond the arc in San Antonio, averaging 1.5 made threes on 4.0 attempts at 38.5% through four games, with hits of 2, 1, 2, and 1.

The Spurs' offensive scheme, centered around Victor Wembanyama's gravity in the paint, creates ample open looks for Barnes on the wing, enhancing his efficiency as a floor-spacer.

Miami's defense has allowed 13.2 threes per game this season and 2.5 specifically to power forwards, presenting a favorable matchup in a game expected to feature perimeter volume.

Our Positive EV tool has the probability of this bet landing at 74.63%, so the odds of 21/20 with BetMGM give us a Positive EV of 52.99% on this play. 

Washington Wizards @ Oklahoma City Thunder

Tip 4: CJ McCollum - Over 3.5 Assists vs Oklahoma City Thunder

As Washington's lead facilitator, CJ McCollum has dished out 5.0 assists per game through four contests, with distributions of 6, 4, 5, and 5, thriving in pick-and-roll actions over 30.5 minutes nightly.

His vision and ball-handling have been key in the Wizards' offense, consistently creating for teammates.

The Thunder, despite their perimeter focus, have conceded 6.1 assists to point guards early on, a gap widened by injuries like Chet Holmgren's absence (back issue), which could open driving lanes for McCollum.

With a career average of 3.8 assists versus OKC in 33 games and recent trends leaning over, this prop offers solid potential at odds around 4/5.

Our Positive EV tool has the probability of this bet landing at 72.42%, so the odds of 17/20 with BetVictor give us a Positive EV of 33.98% on this play. 

Orlando Magic @ Charlotte Hornets

Tip 5: Ryan Kalkbrenner - Over 7.5 Points vs Orlando Magic

Rookie center Ryan Kalkbrenner has impressed in Charlotte, posting 9.5 points per game on an elite 90.5% field-goal percentage through four appearances, with scores of 10, 14, 8, and 6 in 25-minute stints.

His efficient interior finishing and post moves fit the Hornets' paint-oriented attack, where he's capitalized on mismatches.

Orlando's frontcourt has been porous, allowing 24.6 points to centers this season, setting up Kalkbrenner for continued production in a matchup that favors bigs. 

Our Positive EV tool has the probability of this bet landing at 70.32%, so the odds of 4/5 with BetMGM give us a Positive EV of 26.58% on this play.
