Bidding#24 06/02/2018

MrQ: This time the bidding went without interference from opponents. After W opened 1♥ and rebid 1NT, my thinking was: she shows me 15-17 HCP, she has at most 3 clubs and at most 3 diamonds, 4 hearts, so at least 3 spades if not 4 of them. As you can see my partner rebid NT holding 5-card major and I was pretty lucky because I could have ended up with only 2 spades in the dummy. How do you feel about rebidding NT holding 5-card major (especially such a nice one)? How this should have been bid?

Guru: I like the fact that you are playing a 1NT rebid with 15-17 not 15-16. Nothing wrong with that rebid with five heart after 1♥-1♠. Do you play “checkback” after the 1NT rebid, if not you should. There are no doubt different versions of it so look it up on Google or follow this: 2C is “checkback”, rebid of suit shows five and minimum, jump rebid shows five and maximum, 2NT shows four and maximum, 2D shows four and minimum. Hope that helps.


MrQ:
Yes, exactly Checkback Stayman! We haven’t discussed it with my partner but I was previously taught a bit different version:

  • 1♥ – 1♠ – 1NT – 2♣ asking:
    do you have 3 spades (my originally bid major) OR 5 hearts (your originally bid major)?
  • 1♣/♦ – 1♥ – 1NT – 2♣ asking:
    do you have 3 hearts (my originally bid major) OR 4 spades (the other major)?
  • 1♣/♦ – 1♠ – 1NT – 2♣ asking:
    do you have 3 spades (my originally bid major) OR 4 hearts (the other major)?
  • 1♣ – 1♦ – 1NT – 2♣ asking:
    do you have 4 hearts OR 4 spades?

Responses are:

  • 2♦ = none is true
  • 2♥ = question about hearts is true
  • 2♠ = question about spades is true
  • 2NT = both are true

What do you think?

Guru: Keep the checkback as simple as possible is all I can suggest. Keeping it simple is also logical, the only problem with checkback is that if opener opens 1♣ and rebids 1NT, you can no longer play in 2♣. But that’s no big deal. Use your version and make sure you both do it the same way.
