On 2 August 1876, the legendary Wild Bill Hickok was playing five card draw in a saloon in the town of Deadwood in the lawless Black Hills of Dakota.
Aware that his fame was as much a curse as a blessing he rarely sat down to a game of cards without ensuring that his back was to the wall but on this occasion that particular seat was unavailable. He decided to play nonetheless.
It was to prove a fatal error.
Later that afternoon a ranch-hand by the name of Jack McCall walked up behind him and fired once into the back of his head for no other reason than he could boast that he had done so.
The cards that Hickok was holding at the time, two black aces and two back eights, has since become known as the Dead Man’s Hand.
It is the most famous hand of cards in the history of poker. But it does not contain the most notorious playing card.
That dubious honour goes to the Nine of Diamonds – the Curse of Scotland.
There are various versions as to why the Nine of Diamonds sends a shiver down the spine of the Scottish collective.
The most popular theory why it is so known is because of the similarity the playing card has to the family crest of John Dalrymple, the 1st Earl of Stair, who on 13 February 1692 ordered that the MacDonald Clan be put to the sword in the notorious massacre at Glencoe.
The events at Glencoe caused outrage in Scotland even if much of it was less than genuine.
There were many especially amongst the Lowland Scots who considered their Highland kinsmen little better than savages and who would have raised a glass in celebration of their demise not choked on its contents aghast at their fate.
Cattle rustling thieves and unrepentant Jacobites deserved no better so their deaths, however gruesome,would not have been considered a curse by many.
Also, just how many Scots would have been aware of the Dalrymple family crest?
And would they necessarily have drawn the comparison with the Nine of Diamonds in a pack of playing cards?
Another version for the origin of the curse comes just prior to the bloody conclusion of the Jacobite Rebellion of 1745-6.
On the eve of the Battle of Culloden the Commander of the English Army William Augustus, the Duke of Cumberland, later known as Butcher Cumberland, was playing cards when he issued the order that in the coming battle no rebel was to be given quarter.
The young Officer who was to pass the order onto the Regimental Commanders uncertain if he had heard it correctly nervously asked the Duke to repeat what he had just said.
A clearly irritated Cumberland then hastily scrawled the order on the Nine of Diamonds and handed it over.
That night on the other side of Drumrossie Moor Bonnie Prince Charlie was likewise playing cards when it was discovered that the Nine of Diamonds was missing from the pack.
Some of those present considered it an ill-omen and so it was to prove for the following day the Jacobite Army was brutally crushed.
All of this may well have been true but it does not explain why the first mention of the Curse of Scotland had occurred in print in 1710, thirty six years earlier.
Perhaps a more plausible theory is that which concerns Mary, Queen of Scots.
Mary was a Catholic raised in the French Court who was beautiful, flirtatious, and a woman.
If that in itself wasn’t enough to raise the hackles of the predominantly Presbyterian Scots then her love of dancing and games was - whether it was golf, falconry, or playing cards.
Mary particularly enjoyed playing a game known as Pope Joan in which the Nine of Diamonds was the most significant card.
As far as many Presbyterians were concerned the Pope was the anti-Christ and to be playing cards at all was a sinful act, to be playing a game called Pope Joan was damn near heresy.
It was also the case that during the reign of Queen Mary nine priceless diamonds were stolen from Edinburgh Castle by the thief, George Campbell.
They were never recovered and the loss to the Scottish Treasury was such that Mary had to raise taxes significantly to make up for the shortfall.
The theft of pennies from the Scotsman purse and the fury that it evoked plays into their supposed parsimony but does little to explain why it should be considered the Curse of Scotland.
After all, the raising of taxes, then, as now, remains commonplace.
The legend of the Nine of Diamonds as the Curse of Scotland remains vague, perhaps lost forever in the mists of time.
Though with time to ponder some might reflect that the real Curse of Scotland is, and has always been - the English.
This may all change of course on 18 September.
