A price of -1900 is deep odds-on. Bookmakers quote it when an outcome is close to a formality, and the margin they take is proportionally large at this end of the market. Sharp bettors tend to look at the other side of such a market, or at the exchange, where the same favourite is often available a tick or two better.

The vig at -1900

If both sides of a two-way market were priced at -1900, the implied probabilities would add up to 90.00% above 100%. That excess is the overround, or vig; as a share of stakes it is a 47.37% margin for the bookmaker. Removing it leaves fair odds of 2.00 decimal ( +100) on each side.
