Which bids are forcing?

[nigel_k]

With opponents silent, the auction starts 1♣-1♠-2♣-2♦-2♥.

 

2♦ is forcing and ostensibly natural, 2♥ instead of 2♦ would have been natural and forcing.

 

Which continuations by responder are forcing?

To me everything is forcing and i would make my invitation bids without stepping on to 2♦ first, including 2NT.

 

1♣-1♠

2♣-2NT/3♣/2-3♠ and i wont nitpick the red stoppers when bidding 2NT.

 

For some of us 2♣ is wide range, wider than those who plays it strictly 11-14. Depends on how picky you are with opener's jump rebid suit quality and/or reverses. If u are picky with those bids than 2♣ can be as good as 16 hcp.

 

Also, the structure of system and meanings of other bids directly affects the meaning of bids made here. For example we play

 

1♣-2♠ by unpassed hand as (8)9-11 6 card invitational and can not be bad suit. Thus

 

1♣-1♠

2♣-3♠ can be played as forcing and solid suit (or he wld start with 2♦ first if non solid and rebid ♠) or can be played as inability to bid 2♠ at the first place (bad suit inv hand etc..)

I don't think 2N Tis forcing, but anything else is
