Cash bet with an extra place
Enter £10 per part, win odds 5.00, quarter odds, four bookmaker places and three exchange places. Set win lay odds to 5.00, place lay odds to 2.00, and commission to zero; assume no settlement deductions.
The win and place lays are £10 each, with liabilities £40 and £10. A win, standard place or no place produces £0. Finishing fourth produces £20 because it wins the bookmaker place bet but not the exchange place market.
