Opener's Rebid with 4 spades


Opener's Rebid with 4 spades

After responder's 1♠ or 1♠, when should opener show a 4-card spade suit?

We are looking at an auction that begins either 1♠-1♠, 1♠-1♠, or 1♠-1♠.

When opener should show/bid a 4-card spade holding:

  • After 1m-1♠ (because responder could be 4-4 in the majors), for example, after 1♠-1♠, rebid 1♠ with:

♠ KJ76  
♥ 42  
♦ AQ65  
♣ K32.

  • With any unbalanced hand. For example, rebid 1♠ after 1♠-1♠ with: 

♠ K1076  
♥ 2  
♦ AQ2  
♣ K7652.

Rebid 2♠ after 1♠-1♠ with: 

♠ KQ107  
♥ A43  
♦ 2  
♣ AKQJ2.

When opener should "bypass" (ignore -- or not show) a 4-card spade holding:

  • With 18-19 balanced, opener should rebid 2NT (it is up to responder to locate a 4-4 spade fit).  For example, rebid 2NT after 1♠-1♠ with: 

♠ KQJ7  
♥ Q2  
♦ AJ6  
♣ AJ108.

  • With 12-14 balanced, after specifically 1♠-1♠, opener should rebid 1NT (it is up to responder to locate a 4-4 spade fit). For example, rebid 1NT after 1♠-1♠ with:

♠ KJ76  
♥ KJ2  
♦ J2  
♣ A1065.
This is the modern ("Walsh") style, which I highly recommend. Because reponder's 1♠ (natural) won't include a 4-card major (unless he intends to bid again), there is no need for opener to show a 4-card major.

  • After 1♠-1♠, only with exactly 4=3=3=3 and poor spades. For example, rebid 1NT after 1♠-1♠ with:

♠ 9765  
♥ K54  
♦ KQ7  
♣ AJ6.
