So X = majors, 1NT = minors is popular (as above) or simpler yet X = clubs, 1NT majors or minors, 1 level overcalls sound, 2 level overcalls weak is quite playable.
At the other extreme you can play something incredibly simple and still be effective. In Psycho Suction the possible 1-suiter is the suit bid but there is a whole family of defences based on Suction.
Here the overcalls show either one suit or the next higher 2 suits. 1D! = 2 suits of same Rank ( either minors or majors)ġNT! = 2 suits of same Shape ( pointed Sp/Diam or rounded Ht/Cl )Īguably the 'standard' more complex defence in the UK is Truscottįor a 'cool' defence then look up Suction or, better yet, Psycho Suction.
