Balancing 1NT Overcall

1.1.       Balancing 1N

The 1N bid in balancing seat has a different meaning. From an unpassed hand, this shows a strongish hand, 11-15 HCP with a stopper. From a passed hand1N shows a 2-suiter in the lower unbid suits, possibly with the lowest suit being longer (at least 4-5 in length).
 
1N: 11-15 HCP, balanced hand with a stopper, natural responses except for 2§ (Crowhurst) ask. If partner has 12-14 HCP, must have been trapping, bids 2N which overcaller will raise to 3N unless an absolute minimum. Partner is not likely to have an invitational hand in a suit as they would have overcalled, so 3-level bids are preemptive (except for a 3♣ cuebid which shows 5-5 in minors and is non-forcing, other cuebids have no meaning). Other 2-level bids are to play; even a cue-bid would be natural to play in opponent’s suit but for 2§. Texas transfers are also used but its use seems unlikely. With 9-12 HCP responder may bid 2§ to enquire:
Over 1§: 2§: ask
            2¨: 11-13 usually 4¨
            2©: 11-13 four Hearts
2ª: 11-13 four Spades
            2N: All hands 14-15
                        3§: ask for 4 card major
Over 1¨ :2§: ask                                             
            2¨: 11-13 usually 4§
            2©: 11-13 four Hearts
            2ª: 11-13 four Spades
            2N: All hands 14-15
                        3¨: ask for 4 card major
Over 1©: 2§: ask                                             
            2¨: 11-13 usually 4¨
            2©: 11-13 usually 4§
            2ª: 11-13 four Spades
            2N: All hands 14-15
                        3§: sign-off, all other bids GF
                        3©: ask for 4 Spades
Over 1ª 2§: ask                                              
            2¨: 11-13 usually 4¨
            2©: 11-13 four Hearts
            2ª: 11-13 usually 4§
            2N: All hands 14-15
                        3§: sign-off, all other bids GF
                        3ª: ask for 4 Hearts
A 2 follow-up by responder after 2 bids is 4-4in majors.
 
Should 1N be doubled or opener’s partner makes a bid, the same methods as over a direct 1N overcall are used.
