Blooman over 1NT
BLOOMAN OVER 1NT (Published in the March 2006 Bridge Bulletin)
The natural way of bidding over opponents strong 1NT
A convention by Bob Hoffman (hoffy17@comcast.net) and Irv Bloom
Blooman allows you to make the natural overcalls of (2♣,2♦,2♥,2♠) over
opponents 1nt bid, and still have the ability to compete with 2 suited hands.
Blooman is based on the proven premise that a single suited hand of 6 cards
or longer will occur almost 4 times as often as a 2-suited hand 5/5 or longer.
1NT - 2♣, 2♦, 2♥, 2♠ = Strong 5 card suit or 6 card or longer suit
1NT - 3♣, 3♦, 3♥, 3♠ = Preemptive Bids (6-card or longer suit)
1NT - 2NT = Shows Clubs and diamonds
1NT - X - P - 2♣ (relay bid)
P - 2♦ (hearts and spades); 2♥ (hearts and a minor); 2♠ (spades and a minor)
If responder has only one or two of doubler’s major, he may bid 2nt,
asking opener to bid his minor suit.
Strong Bids (8+ tricks)
1NT - X - P - 2♣ (relay bid)
P - 3♥, 3♠ (strong 6-card or longer suit)
1NT - X - P - 2♣ (relay bid)
P - 2NT (strong 2 suited hand with clubs and diamonds)
BLOOMAN over INTERFERENCE
The following are additional advantages when using Blooman.
When opponents transfer to hearts and we hold 2 or more hearts, we
know that partner has 5 spades and an unknown minor.
1NT - X - 2♦(transfer) - 2♠ = 3+ card support for spades
2nt = support for both minors & less than 3 spades
When opponents transfer to spades and we hold 2 or more spades, we
know that partner has 5 hearts and an unknown minor,
1NT - X - 2♥(transfer) - 3♥ = 3+ card support for hearts
2nt = support for both minors & less than 3 hearts
We always try to observe the Law of Total Tricks.

It has been discovered that a one suited hand 6+ cards or longer occurs almost
Four times as often as a two suited hand 5/5, 6/5 or 6/6

opponents opening 1NT as natural bids.
Easy to remember and very effective when used.
