When partner decides to bid 1 of a major in the 3rd position in bridge…sometimes their bid can be weaker than a normal opening. It’s called a 3rd in hand opener. You can also do it in 4th position as well…usually when you hold the spade suit.

So we use an artificial bid of 2♣ or 2

The bid of 2♣ / 2 asks opener for their strength.

Very simply opener rebids their major if they are weak and bids anything else to show they have a sound opening bid.

Rebidding 2 of the major shows a hand with sub opening values and any other bid now shows at least normal opening values.

This prevents the partnership from getting to the 3 level when only 2 of a major can make.

Example Hands

So all of these hands you could open 1 of a Major in third or 4th

  1. ♠ – AQJ54 – Q984 – 6 ♣ – KQ107
  2. ♠ – 4 – AQ1097 – A986 ♣ – 974
  3. ♠ – AQJ105 – J102 – Q63 ♣ – 32
  4. ♠ – KJ10986 – A43 – KQ4 ♣ – 7
  5. ♠ – AK10986 – KQ3 – A4 ♣ – K7

After partner bids 2♣ Reverse Drury each hand would respond :-

  1. Bid 2 – Normal opening strength and shows 54 shape
  2. Bids 2 – weak opener…don’t go on partner
  3. Bids 2♠ – weak opener…don’t go on.
  4. Bids 4♠ – no other suit to show fast arrival…no slam interest
  5. Bids 3♠ – slam interest
