አማርኛ A price boost raises the odds on a selection the bookmaker chooses, usually stake-capped. Because the base price includes margin, a boost often merely returns you to fair — but occasionally, especially on exchange-comparable markets, it genuinely crosses above it.
The check is mechanical: compare the boosted price against the best un-boosted price and the exchange. Boosted 2.20 where sharp books quote 2.10 is real value in a capped size; boosted 2.20 where the fair price is 2.35 is marketing arithmetic.
Boost: 2.00 → 2.20, max £10 stake. The exchange trades the same outcome at 2.16, roughly 2.12 fair after commission. Taking the boost carries (2.20 / 2.12 − 1) ≈ +3.8% expected value on the capped stake — worth taking, and worth not extrapolating to the operator's unboosted prices.
