Hello Bridge friend!
This is the third in a series of newsletters from Topbridge. This time I would like to give you some hints on bidding after partners 1NT opening or overcall.

 

System

Answers to 1NT opening or overcall.

2Clubs = Stayman
2Diamonds / 2Hearts / 2Spades / 3Clubs = 4 Way Transfers
2NT = Invitational

Stayman is used to locate 4-4 fit in major after 1NT - opening or overcall

1NT
      2Clubs = Stayman 
                   2Diamonds = no 4 card major
                   2Hearts = 4 card hearts (may also have 4 card spades)
                   2Spades = 4card spades, (denying 4 card hearts)

After 1NT opening or overcall, 4 Way Transfers are used to make the strong hand declearer. With 5+ hearts you bid 2Diamonds. With 5+ spades you bid 2Hearts. 2Spades is a transfer to clubs(6+), and 3Clubs is a transfer to diamonds(6+).

A jump to 3Hearts, 3Spades, 4Clubs or 4Diamonds after partners 1NT is forcing with
6+ cards. A transfer bid followed by 3 in major or 4 in minor is invitational. A direct jump
1NT - 4NT is invitational to 6NT.
 
NOTE: Keep within the limits of the 1NT opening(15-17 balanced) and overcall(15-18 balanced). Your partner will make his judgement based upon these facts.

When opponents interfere !!

This change the situation and we have to switch the system off!!!!
If you hold a medium to strong hand in these situations you have some possibilities depending on opponents action. You can redouble their double or cue-bid their overcall suite with a strong hand. A double of an overcall is for penalty.
If you hold a weak hand you have to keep the bidding on the lowest possible level.
For this you need 2Clubs,2Diamonds,2Hearts and 2Spades as naturale nonforcing bids after opponents double.
If opponents interfere with an overcall of e.g. 2Diamonds, you will need 2Hearts as a fight for contract.
