Cash each-way bet
Use £10 per part, bookmaker win odds 5.00, quarter odds (1/4), four places at both bookmaker and exchange, win lay odds 5.00 and place lay odds 2.00. Set all commission to zero; assume no settlement deductions.
Lay £10 on the win market (liability £40) and £10 on the place market (liability £10). The combined result is £0 for a win, a standard place or no place.
