Suction is a bridge convention used for intervention over an opponent's 1NT opening.
When suction is agreed, a suit overcall of a 1NT opening is conventional and denies the suit actually bid. It shows either (1) a one-suiter in the next higher ranking suit or (2) a two suiter in the other two suits.
If responder passes, advancer is required to bid the next higher ranking suit. If overcaller has the one-suited hand, he passes. Otherwise, he bids yet the next higher suit, showing that suit plus the remaining, unbid suit. Advancer then takes a preference by passing or bidding the remaining suit.
To summarize:
- 2♣ shows either diamonds or both majors
- 2♦ shows either hearts or both black suits
- 2♥ shows either spades or both minors
- 2♠ shows either clubs or both red suits
[edit] Restricted use
Suction is not permitted in events governed by the ACBL General convention chart, except as a defense to artificial opening bids (such as precision, strong 2c openings, flannery, etc.).
