The ACBL NT article was not esp. balanced. Anyway, my favorite defense is extended HELLO. It meets my 2 most important criteria, having a direct seat pen X, *and* being able to show major one suiters at once, with the suit known. Also often has a transfer effect. In direct seat: X = Penalty (Most likely playing strength, not 'equal hand or better', or any such rubbish) 2♣ => Relays to 2♦...diamonds or a Major/minor 2♦ => Hearts 2♥ => Majors 2♠ => Spades 2NT => Relays to 3♣. Either clubs, or a near-GF single suiter in ♦/♥/♠. Overcaller rebids the suit with a strong hand. 3♣ => Minors 3♦ => Majors, strong 3♥/3♠ => Preemptive In balancing seat: 2♣ and up retain their current meaning. X becomes a relay to 2♣, showing a 5cd Minor and a 4 card major. Over 2♣ opener bids 2♦ with ♦ + a major, and responder can scramble for the major...with clubs overcaller just bids the major over 2♣, allowing responder to run back to 3♣ if desired.
