Obstructive bidding
Pre-empts
Pre-emptive bidding stops the opposition from finding the right contract — or at least makes it hard. The danger is that pre-empting at the wrong vulnerability can hand them a bigger score than they'd otherwise get.
The rule of 500
When pre-empting first or second in hand, apply the rule of 500:
- Non-vulnerable, you must hold 6 sure tricks.
- Vulnerable, you should hold 7 sure tricks.
Three off doubled non-vulnerable and two off doubled vulnerable both give a 500 penalty.
Third-in-hand pre-empts after two passes are simply obstructive — the rule of 500 doesn't apply, but common sense does. As a corollary: you must have a very good reason to pre-empt vulnerable against non-vulnerable.
