Hi:
Today I met a special problem while I looked on Teams D20 FlightA T2 .
Its basic bidding at below:

---

2♥ is forcing or not?

So I consult with my friends,some people think it is not forcing since 2♥ is a free bid,not cuebid,not raise bid.Some think it should be forcing a round.

Here is example hand at Teams D20 FlightA T2

---

The result ：2♥E+2

Another table:

---

The result ：4♥E+1

Here is my thread at Gib robot discussin.

As you know,2♠ as a new suit is not forcing in the competitive auction,now there is a new problem.
For north player,how to look for ♠ fit? how to creat forcing sequences?

Now I don't know how to take next action in the two hands above,can you help me?
Many thanks.

It depends on partnership agreement. Generally I play with many people that new suits after an overcall are non-forcing constructive. Some might think a 2/1 new suit is stronger than that - but others still play non-forcing constructive except if on the 1-level where they are forcing. Some people play all these are forcing by UPH.

My preferred solution is transfer advances where the east hand would bid 2♦ showing hearts and west would compete the transfer if and only if they'd pass a non-forcing natural 2♥. If west bids something else it is natural and shows extras. If east bids on over the 2♥ complete it is generally natural (returning to ♠ shows a mild invite with length/features in hearts). When I play transfer advances (which are on between the cue suit, diamonds here, and one less than the overcall suit) the suits that you can't transfer to (clubs in this case) I play as F1 by UPH and NFConst by PH.

I prefer this, but of course the cue-bid has to do extra duty in this style. I play what partner likes, which varies; this is why the vote options should include "either".

Some play that 1/1 and 2/2 are forcing, while 2/1 is not.

I don't play transfer advances, but I think that they are the way to go.

NF, although as always partnership depend.

NF, does not mean junk / weak, a new suit would show a constr. hand,
upto inv. strength.
After a 1 level overcall, you could play a change of suit at the 1
level as forcing, which simplifies discovering 44 fits in a major,
not uncommon, similar after a 2 level overcall, a change of suit could
be played as forcing, which is also not uncommon.

And for simplicity / symmetric reasons, you could play change of suit as
forcing.

In the end your overcall style does matter.

With kind regards

It's a rather common agreement to play 1 and 3 level bids as advancer forcing, and 2-level bids non-forcing constructive but I've seen virtually every possible configuration so you have to discuss this with partner.

[NickRW]

One solution I have seen proposed is that a cue from advancer in 4th seat can include this hand (as well as a good raise) - which helps in some situations - though it rather depends on whether it guarantees 5 or 6 cards in your suit when you reveal it. If 6 it leaves the problem of what do with a good opening hand and only a 5 carder. If 5 it leaves opener wondering whether it could be 6 and what to do with a doubleton support when the auction has got quite high already.

The majority of partnerships will use this bid as non-forcing. I play it as non-forcing, constructive.

I have a meta-rule for this:

If RHO passes, it's forcing.
If RHO acts, it's constructive but not forcing.

Example:

(1♥) 1♠ (pass) 2♦ = forcing
(1♥) 1♠ (1NT) 2♦ = not forcing

Reasoning is that when RHO acts, odds of our side having a game on diminish.

In your case it would be forcing.
