Sharp bookmakers (and betting exchanges) run low margins, accept large stakes, and shape their prices from the flow of professional money — their lines are treated as the market's reference truth. Soft bookmakers target recreational customers with bonuses and promotions, run higher margins, move slower on news, and restrict accounts that win consistently.
The practical edge map follows directly: value is found most often at softs whose slow or promotional pricing lags the sharp consensus. Comparing a soft book's price against the sharp/consensus fair line is precisely the pattern our value detection uses. The trade-off to know about: consistently taking those prices tends to earn stake limits at soft operators — a badge of honour, but a real constraint.
Sharp consensus prices a side at 1.95 (fair ~51%); a soft book still shows 2.15 from yesterday. That 10% gap is a classic soft-book value spot — and exactly the kind of discrepancy that closes within hours.
