Rolling Blackwood
aka Sliding Blackwood

The origin of this variation is unknown. Rolling Blackwood, or Sliding Blackwood, is a variation of the Blackwood Convention. It takes into account that two partners could reach an unsafe contract in the Minors using the normal Blackwood convention, which could take them past the level of a safe contract.

Some bridge players will employ a different form of Blackwood if the established trump suit is a Major suit.

The following auction should illustrate the concept behind Rolling Blackwood, aka Sliding Blackwood.

Dealer: North
Vulnerable: North-South

South
1 3
4 No Trump = Blackwood 5 : 1 Ace
Normally, 5 No Trump would be asking for Kings.
The Rolling Blackwood convention states that the lowest-ranking non-trump bid is used to ask for Kings.

5 would then be the correct bid.

Responses:
5 :
0 or all 4 Kings
5 NT:
1 King
6 :
2 Kings
6 :
3 Kings

This variation of the Blackwood convention enjoyed some popularity at one time. The problem with the Minor Suit Slams is real and this method helped to solve it. However, this variation has lost some ground and is rarely used by bridge players.

Check with the governing body and/or the bridge district and/or the bridge unit prior to the game to establish the guidelines applied. Please include the particular feature on your convention card in order that your opponents are also aware of this feature during the bidding process, since this information must be made known to them according to the Laws of Duplicate Contract Bridge.
