3 way Drury

After pass – 1M, bidding 2♣ or 2♦ is Drury. 

2♣ shows either 4 card support and 7 to 9 HP without a singleton (with a singleton we bid Bergen Modified), or 9+ to 11- HP and 2 card support. Can hold 5 card minor suit (or ♥ after 1♠). 

2♦ shows 3 card support and 9+ to 11- HP.

Drury is "on" only when no competition. 

If 2♣/♦ get doubled, general rules regarding doubles of artificial bids apply. 

If 2♣/♦ are overcalled, the continuation is natural.
