Phil Mickelson and Vijay Singh's former caddie Kip Henley has recently come out and said a number of players are seen regularly cheating on Tour.
We therefore thought what better time to reveal the dark art of cheating at golf in the amateur game and how to spot the criminals and catch them red-handed, and red-faced.
Here’s the GolfMagic guide to golf cheats and how to stop them in their tracks...
TOUR CADDIE: CHEATING HAPPENS ALMOST EVERY WEEK ON TOUR
#1 - THE COIN MOVER
Watch how the cheat marks the position of the ball on the green.
Invariably they will use a big coin, like a 50p or inch-diameter foreign currency, carefully sliding the coin as far as possible under the ball.

When replaced, the distance between ball and coin will be at least an inch nearer the hole or slightly to the side to avoid a spike mark or blemish on the green.

Occasionally they will surreptiously toss another coin a few inches, or even feet, nearer the hole (depending on the length of putt they face) and ignore the original marker to give themselves a closer putt.
Watch too when a marker in an opponent’s putting line goes down nearer the hole when measured a putter head’s length – the angle changes when replaced and the cheat steals an inch or two.
