Re: hcp sanctions ( 17:54:15 FriAug 15 2003 ) |
ACBL convention regulations make no mention of the rule of 18 or similar rules. On the General Convention Chart, opening at the one level by partnership agreement on less than 8 HCP is prohibited.
The only restriction I can see for natural preempts at the two and three level (or higher, for that matter) is that if you have an agreement to open a weak two on a range greater than 7 points or with fewer than 5 cards you may not use conventional calls thereafter.
You may find, particularly in clubs, that the actual rule is "whatever the TD - or some influential player - doesn't like is prohibited" even when the GCC is nominally in force.
