1H-1S-1NT-2C-2D-2H/3H

[kgr]

1♥-1♠

1NT-2♣

2♦-?

 

2♣=crowhurst

2♦=minimum

 

Responder now bids:

2♥=3c♥, non-forcing (invite hand)

3♥=3c♥, GF

 

What is the advice on the number of Spades that responder should have?

4c♠ searching for 4-4 fit;

OR any 5c♠;

OR good 5c♠ searching for light slam, ...?

I think that a 2H rebid should promise only two hearts and should deny a fifth spade. With a 5-2 I'd rather play 2M than 2N. If responder has 5 spades and 2 hearts, he'd preference spades.

 

I personally don't like to introduce four spades when I have a heart fit and only like to introduce 5 spades (when I have a heart fit) when I have game invitational values or better. That way, If I bid 1S and later GF opposite a minimum hand, I'm showing five spades.

I assume you're playing a 4 card major system. I think responder should have a 5th spade when he rebids 2♥, but isn't promising a 5th spade when he rebids 3♥. This is assuming a style where you bid 2♥ with 6-9 and 3 card support.

I assume you're playing a 4 card major system.

5c Major

This is assuming a style where you bid 2♥ with 6-9 and 3 card support.

2♥ is Good 7 to 10 (we bid 1NT with less)

[lowerline]

Assuming 4+crd spades and 3crd hearts:

With a weak hand and support you show that asap (don't bid spades)

With an inv+ hand you bid spades first and support later

 

All natural:

1♥-1♠

1nt-?

 

2♥ = inv

3♥ = GF

 

Don't know what you need Crowhurst for...

 

With 3crd spades opener can bid them now and reveal the possible double fit
