The Carnoustie Meltdown

I am no golfer and I have played golf more often on a games console than on a real golf course. Either way even I know that if I am 3 shots ahead with one hole to go and the final hole is a par 4 then even with a double bogey I will still win the competition. Frenchmen Jean Van de Velde was in this exact position at the British Open in 1999 and even when things started badly, instead of playing safe things in fact just got more ludicrous.
