Two Suited Overcalls

These methods are suitable for any system, not just Precision.

Basic 2 Suited Overcalls


Have been convinced by Ian Payn (see http://www.ebu.co.uk/publications/EB-web_library/2009/October/debate.pdf )that the cost of losing 3§ as an overcall bid and other difficulties not to use the Questem convention(Ghestem inverted). Instead Michaels and unusual 2NT are the calls.


cue-bid over a minor = both major suits 5-5. 2NT is responders asking bid.

cue-bid over a major = 5 of other major and 5 of an unspecified minor. 2NT is responders asking bid.

2NT = two lowest unbid 5-5. Cue-bid is responder’s asking bid.

I strongly believe that these 2 suited bids should be at least 5-5 in length and the difference in length should be at most 1 card. With 5-4, even in the major, simply overcall in your 5 card suit. 6-5, 6-6 or 7-6 are ok. However, with 6-4, 7-5, 7-4, 8-4 or 8-5 again bid your longest suit.

I used to believe that strength should be mini-maxi, either 6-11 or 16+ pts. However, I found whenever I had the strong hand and bid again, my oartner didn’t believe it and we missed slam. Also, Mike Lawrence in his book Overcalls is against a mini-maxi approach. So the strength should be 9+ HCP at IMPs, lower points allowed at matchpoints, but remember if you don't have a chance to play contract opponents will be able to read you cards like there exposed.

Should you have 16+ HCP and you get another chance to bid,

 Balancing cue-bid

From an unpassed hand this shows a strong 2-suiter of unknown suits. Must use unkown suits as 2NT in this case would be 19-21 Balanced.  Responder, bids as follows

            new suit: good  support for this suit
            NT: weak hand wishes to sign-off
            Cue-bid: strong responding hand, slam possible

            Overcall responds as follows:
            To a new suit:   
                        Raise: if that is one of the suits.
                        Jump Cue-bid: no losers in suit, and has this suit.
                        New suit: doesn’t have this suit, has other 2-suits.
                        Cue-bid: does have this suit, slam interest.

            To a NT bid:
                        Bid lowest of a 2 suiter

            To a Cue-bid:
                        Bid lowest of a 2 suiter
                        Jumping with exceptional strength

From a passed hand a cue-bid is modified Michaels, will show the higher two unbid suits,
but weak. Bidding proceeds similar to a direct modified Michaels above

Balancing 2NT


From an unpassed hand shows a strong balanced hand, 19-21 HCP. Systems
ON. From a passed hand this shows a weak 2-suiter of the 2 lowest unbid suits, bidding proceed
as over a direct call.
