Favourites win more games. But at -200 you need a 67% win rate just to break even after the vig. The public backs favourites because they "feel safe" — but the math doesn't work. Sharps target inflated underdog lines where the true probability significantly exceeds the implied probability at inflated odds. The psychology of loss aversion makes recreational bettors consistently take bad value on short-priced favourites.

Every bookmaker prices odds below true probability. A fair 50/50 market = odds of 2.00 each way. A typical sportsbook offers 1.91 on each side. That 4.5% margin is the vig — pure house edge on every single bet, paid by every bettor who doesn't find genuine positive expected value. Over 1,000 bets at -110, even a "good" 55% win rate produces a small loss after the vig. Finding +EV bets is the only mathematically sound approach to long-term sports betting.

A "steam move" is a rapid, uniform line shift across multiple books simultaneously — almost always caused by sharp action. But not all line movements are genuine. "Boiling the books" is when a retail sportsbook shifts their line to balance action after early recreational bets (not sharp money). Real steam: multiple books move simultaneously in the same direction with no obvious news catalyst. Fake steam: single book moves, then stabilises. The difference is detectable with live odds monitoring — which is why sharp bettors use line-tracking tools.

Flat staking: bet the same amount every time regardless of confidence. It sounds boring. It's mathematically optimal. The Kelly Criterion promises faster growth but requires precise edge estimation — and a single miscalculation can destroy your bankroll. We recommend 25% Kelly fractional staking — aggressive enough to grow a bankroll over time, conservative enough to survive the inevitable variance that kills Kelly bettors who overestimate their edge.

After a big win, public money floods the winning team, driving their line too short. After a demoralising loss, lines drop too far on the loser. Books shade their lines toward this public sentiment — they know recreational bettors bet on what they just watched. Sharp bettors exploit these overreactions by betting the other side immediately after the market overcorrects. The "bet the bounce" and "fade the hangover" strategies are well-documented market inefficiencies that persist because the public never learns.

The closing line is where the market settles just before a game starts. Getting better odds than the closing line on a consistent basis is the definitive indicator of genuine betting skill. If your odds at 2.10 close at 1.85, you had 12% closing line value — that's an excellent bet. If your 1.95 opens but closes at 1.85, you took poor value. Professional bettors track CLV (Closing Line Value) on every single wager. If you're not beating the closing line by at least 5% on your wins, the vig has likely consumed your edge.

Asian Handicap markets attract more professional money than any other football betting market. Because the draw is eliminated, AH lines are tighter and more efficient — which means inefficiencies (when they appear) are more significant signals. When an AH line moves from -1.0 to -1.5 without injury news, sharp money has arrived. Monitoring AH line movements across multiple books is one of the most reliable ways to track where professional money is flowing.
