  "description": "A teaser lets you move the spread or total in your favor on multiple legs (commonly 6, 6.5, or 7 points in the NFL) in exchange for reduced payout odds compared to a straight parlay. A pleaser does the opposite — you move the line against yourself for a much bigger payout, essentially betting a worse number for a lottery-ticket-style return. Both are two-team-minimum combo bets that live or die on every leg hitting. This calculator takes the number of legs, the points moved, and the payout odds your book offers for that teaser/pleaser tier, then computes the break-even win rate per leg needed to profit, so you can judge whether the discounted odds are worth the extra points. The classic trap is the 'Wong teaser' concept, crossing key numbers like 3 and 7 in the NFL with a 6-point teaser, which meaningfully improves true win probability per leg — this calculator doesn't know which numbers you're crossing, so pair it with actual key-number research rather than betting teasers blindly on any two games.",
  "formula": "Break-even per-leg win rate = (1 ÷ decimal payout)^(1/legs). Total parlay probability needed = break-even^legs = 1 ÷ decimal payout.",

  "faq": [
    {
      "q": "Why do teasers pay less than a straight parlay?",
      "a": "Because moving the spread in your favor raises each leg's true win probability, so the book compensates by cutting the payout odds. A standard 2-team 6-point NFL teaser often pays around -110 to -120 instead of the roughly +260 a straight 2-team parlay at -110 legs would pay, since teaser legs are individually much more likely to hit."
    },
    {
      "q": "What is a 'Wong teaser'?",
      "a": "Named after gambling author Stanford Wong, it refers to using a 6-point teaser specifically to move a spread across the NFL's most common margins of victory — 3 and 7 points. Teasing a -8.5 favorite to -2.5, or a +1.5 underdog to +7.5, crosses both key numbers and meaningfully boosts true win probability beyond what a generic 6-point move on a random line does."
    },
    {
      "q": "Are pleasers ever a good bet?",
      "a": "Pleasers require every leg to beat a worse number than the original line for a much bigger payout, which mathematically makes them a longshot bet with high variance and typically negative expected value unless you have a specific, strong reason to believe your teams beat the tougher numbers. Treat pleasers as entertainment bets, not core strategy."
    },
    {
      "q": "How many legs is optimal for a teaser?",
      "a": "Two-leg teasers, especially Wong teasers on key numbers, have the best documented track record historically. Adding legs increases payout but multiplies risk — needing all 5 or 6 legs to hit even at improved individual probabilities usually pushes expected value back toward breakeven or negative, since one weak leg sinks the whole ticket."
