Best odds guaranteed races, paired to the win lay

Best odds guaranteed (BOG) means the bookmaker pays at the starting price when it beats the price taken. The BOG board serves the races where a bookmaker offers it: win back prices, best first, each paired to the exchange win lay, lowest first, with the money available.

What the board holds

Horse racing, pre-match, win market. A row is on this board because the bookmaker offers BOG on that race; every other bookmaker's price for the race is on the standard board.

Each row carries the bookmakers' back prices and links, and the exchange lay prices for the same horse with the money available at each.

The shape

The BOG board has the standard board's shape: a back list and a single lay list, no place terms. What sets it apart is which races and bookmakers it holds, not a field.

Working a row

A BOG row is a win back price against a win lay, which is what the matched betting calculator sizes. The docs carry the full response shape.

What you get

Only Best odds guaranteed racesWin prices from bookmakers offering BOG on the race.
The win lay beside itExchange lay prices for the same horse, each with the money available and a link.
One schemaThe standard board's shape, so a BOG view is a path change.

What it does not do

Pre-match only, not in-play. The board carries the prices on offer now. The starting price is set at the off and is not in the feed, so what BOG pays on the day is not something a row can show.

Questions

  • What is Best odds guaranteed?

    A bookmaker's promise on a race to settle a winning bet at the starting price if that is bigger than the price taken.

  • Does the feed carry the starting price?

    No. The board carries the prices on offer before the race; the starting price is set at the off.

  • How is it different from the standard board?

    Same shape, different set: the BOG board holds only the races and bookmakers where BOG applies.
