• Horse racing uses parimutuel (pool) betting, NOT fixed-odds like sports betting
• All bets go into a pool; the track takes its cut (called “takeout,” typically 15–25%)
• Remaining money is split among winners proportional to how much they bet
• This means odds change right up until post time as more bets come in
• Morning Line (ML) odds are just estimates — they’re the track handicapper’s prediction of where the odds will land, not a guarantee
• The tote board shows live odds that update every 60 seconds

• Most bets at the track have a $2 minimum (some exotics allow $0.50 or $0.10)
• When odds are listed as “5-1,” that means $5 profit per $1 wagered, so a $2 bet returns $12 ($10 profit + $2 stake)
• Win pays the most, Place pays less, Show pays the least — but each is progressively easier to hit
• Don’t think of Show bets as “bad” — they’re a lower-variance way to play a strong opinion

• Study the program or Daily Racing Form before betting — look at speed figures, jockey/trainer records, and recent form
• Set a bankroll BEFORE you arrive and stick to it (this app helps with the 20% daily budget rule)
• Start with straight Win bets on horses you have conviction on — exotics come later
• Watch a few races before betting to observe the track surface and see which running styles are working
• “Chalk” = the favorite. A “bridge jumper” bet is a large Show bet on a heavy favorite — low return but high hit rate

Takeout varies by bet type and track:

• Win/Place/Show: typically 15–17%
• Exacta/Trifecta: typically 19–22%
• Pick 4/5/6: typically 22–25%

• The Kelly Criterion suggests betting a percentage proportional to your edge — but most recreational players should cap at 5% per bet
• This app’s 20% daily budget rule is designed to keep you in action across 4-5 bets per day
• Never chase losses — if you lose your daily budget, you’re done for the day
• Track every bet (the Results tab does this for you) — review weekly to find patterns in what you’re good at

• Betting every race: the best handicappers PASS more races than they play
• Only betting favorites: favorites win ~33% of the time but rarely at profitable odds
• Ignoring the odds: a great horse at 1-5 odds is usually a terrible bet; a decent horse at 8-1 can be excellent
• Over-boxing: a $2 Trifecta box with 6 horses costs $120 — know your cost before you click
• Emotional betting: never bet a horse because of its name, colors, or your “gut feeling” without data

• A bet has positive EV when the true win probability exceeds the implied probability of the tote odds
• Implied probability = 1 / (decimal odds). At 4-1, implied probability = 20%. If you estimate the horse wins 28% of the time, that’s an 8% overlay
• This app’s Advice Engine calculates overlay as: modelProb - impliedProb (a straight percentage-point difference, matching the worked example above) — values > 0.08 (8 points) flag a horse as a “Value Play”
• Professional bettors focus exclusively on overlay — they don’t care if a horse “wins,” they care if it wins MORE OFTEN than the odds price in
• Key insight: you can be profitable betting horses that lose 70% of the time, as long as the 30% wins pay enough to overcome losses + takeout

• Dutching: betting multiple horses in the same race, sized so that any winner returns the same profit
• Formula: stake_i = (totalStake × impliedProb_i) / sum(impliedProbs) for all selected horses
• Best applied when you can eliminate 40%+ of the field but can’t narrow to one horse
• Spreading in exotics: using a Key horse with multiple “with” horses rather than boxing, to reduce cost while keeping the high-probability horse anchored

• The single most predictive factor in route races (1 mile+): the pace scenario
• Classify every horse as E (front-runner), EP (presser), P (mid-pack), S (closer), SS (deep closer)
• Count the “E” and “EP” horses: 0-1 = slow pace (favors speed), 2 = moderate (honest), 3+ = hot pace (favors closers)
• Lone speed is the most powerful angle in handicapping — a front-runner with no early challengers can dictate tempo and save energy
• In sprint races (under 7f), pace is less decisive — raw speed figures dominate

• Track trainer stats in specific situations: first-time starters, turf-to-dirt, layoff returns (60+ days), equipment changes (blinkers on/off)
• Some trainers have 30%+ win rates in specific spots but 12% overall — the specific angle matters more than the overall number
• Jockey/trainer combos that work together frequently often outperform either individual’s stats
• “Barn moves” (horse transfers to a new trainer) are high-value angles, especially when moving to a top barn

• Exactas: Rarely box — instead, play two straight exactas if you have a strong opinion on the winner. $2 EX 3/5 + $2 EX 3/7 costs $4 and gives you a key position. Boxing 3-5-7 costs $12
• Trifectas: Key your strongest horse on top with 3-4 “with” horses underneath. Key cost = base × n × (n-1) where n = with-horses. Much cheaper than full box
• Pick 4/5/6: Use “spread” legs (many horses) in races with no standout, and “single” legs (one horse) in races with a strong opinion. The ideal ticket has 2-3 singles and 1-2 spread legs. A Pick 4 with singles of 1×1×4×6 = 24 combinations ($48 at $2) vs full spread 4×4×4×4 = 256 combinations ($512)
• Daily Doubles: The most underrated exotic. Lower takeout than Trifectas/Supers, and you only need two winners. Use them to create value when one leg has a clear standout

• Flat betting: Same amount every bet. Simple, prevents overexposure, but doesn’t maximize edge
• Proportional betting: Bet a fixed % of current bankroll (e.g., 3%). Automatically scales down during losing streaks and up during winning streaks
• Kelly staking: Optimal bet size = (edge / odds). If you estimate 30% win probability at 4-1 odds: Kelly = (0.30 × 5 - 1) / (5 - 1) = 12.5% of bankroll. Most pros use “fractional Kelly” (half or quarter Kelly) to reduce variance
• Session management: Set stop-loss (e.g., -40% of daily bankroll) and stop-win (e.g., +100%) targets. When either hits, walk away
• Track your ROI by bet type — most players find they’re profitable in one or two bet types and losing in others. Double down on your strengths

• “Steam” = odds dropping rapidly, usually indicating sharp (professional) money. Late steam on a non-obvious horse is the strongest signal
• “Drift” = odds rising. Can mean insiders are NOT betting their own horse — a negative signal
• Watch the late odds changes (final 2 minutes before post) — this is when sharp money tends to appear
• Pool size matters: in small pools ($10-20K win pool), a single large bet can distort odds. In large pools ($200K+), significant moves more likely represent collective sharp action

• Results-oriented thinking is the enemy. A correct bet that loses is still a correct bet — evaluate process, not outcome
• Keep a betting journal (beyond just results) — note WHY you made each bet. Review weekly to identify pattern biases
• The concept of “due” doesn’t exist in racing — each race is independent
• Fatigue kills edge: your worst bets will come late in the card when you’re tired and chasing. The 20% budget rule prevents this
