martingales
Equine head-lowering straps
Martingales are straps in horse tack that connect the girth to the bridle or noseband, preventing a horse from raising its head too high.
In sailing, a martingale is a stay that braces the jib boom against upward pull.
In gambling and probability theory, a martingale is a betting strategy that doubles stakes after each loss, or more technically, a sequence of random variables where each expected future value equals the current value regardless of past outcomes.
