The Lay Fixed Liability Staking Plan allows us to always know how much we could lose on each bet. Let us say that we do not ever want to risk more than £50 in any one bet. The horse we are interested in is 4/1 of 5 in decimal terms. The stake we would use is £12.50. If the horse were to lose we would lose £50. If the horse was to win we would win £12.50.
