You are a bit thin to reverse, but decide to upgrade based on the good holding in partner's suit.
Traditional Methods
Say you treat the reverse as a one-round force and play traditional continuations - so you need to bid the 4th suit or jump to create a strong continuation. On the East hand above you presumably bid a non-forcing 2NT now. What do you bid next as west? Do you bid 3♠? And is it non-forcing?
Ingberman
Let us now suppose that you play 2NT as Ingberman (or Lebernsohl) as described here, presumably you also bid 2NT as East - a relay with a minimum strength hand? West rebids 3♣, as requested and East bids what? 3♦ false preference? 3♥ - a likely 4-3 fit? Whichever East chooses (3♦/3♥) would you now bid 3♠ as West? And is that forcing?
Reverse Lebensohl
As a final thought, it has been suggested that we could play "Reverse Lebensohl" in this situation - i.e. all strong hand bid 2NT and three level bids are non-forcing. Is this playable? Does anyone have experience of this method?
Thanks
