5. A pre-empt too far

This was a spectacular example of aggression back-firing. The usual results at a recent Swiss Pairs event were either 5♣ by EW or 5♦ by NS doubled but only down one. Only one EW reached 6♣, when an adventurous South decided to open with a Weak 2♦! West bid 3♣ and North jumped straight to 5♦, leaving East little option but to bid 6♣.
