RHO Partner LHO You 2 Double Pass ? ? ?

You might wish to bid 3 with either: a)J43 KQ3 KJT95 J2 or b)J43 42 JT9876 43

Lebensohl provides a method of distinguishing between weak and strong hands.
• With hand a), the immediate bid of 3 is in order.
  
• With hand b), a bid of 2NT warns of a possible weak hand. The doubler, if holding a standard takeout double of the weak two opening, then bids 3. You now bid 3 and partner must Pass.

You might decide that about 8 points in support of a regular takeout Double is adequate to forego the Lebensohl 2NT prelude.

Thus, after a weak 2 opening and partner's Double, with:
1. T93 74 A9643 K53 respond 2NT, intending to bid 3 after partner's 3 relay.
2. QT3 74 A9643 K53 respond 3 to show a good hand.
