When partner opens a suit at the one level then he usually has 12+ points and No Trump responses are generally defined as 1NT (6-10), 2NT (11-12), 3NT (13-15). |
|
| |
|
|
| |
But when partner makes a 1-level overcall things are different. Partner has a 5 card suit but may have as few as 7 points, so you need more points to respond in No Trumps (and also a good stopper(s) in the suit that LHO opened). |
|
| |
|
|
| |
No Trump responses to a 1-level overcall are as follows: - |

Consider the four hands above, and the action you would take if : |
|
| |
| (a) |
Partner opened 1♠ (assume that 2NT is natural and not Jacoby 2NT), or |
| (b) |
LHO opened 1♦ and partner overcalls 1♠. |
|
|
| |
|
|
| |
| Hand A: |
(a) |
1NT, this is a ‘courtesy' bid – you are obliged to bid with 6+ points. |
| |
(b) |
Pass. You are under no obligation to bid over a simple overcall. |
| |
|
|
| Hand B: |
(a) |
2NT, 11-12 points. |
| |
(b) |
1NT. Partner may have as few as 7 points and so 2NT would be too high. |
| |
|
|
| Hand C: |
(a) |
3NT, 13-15 points |
| |
(b) |
2NT, 13-14 points |
| |
|
|
| Hand D: |
(a) |
2♣, you do not bid 2NT as that would deny a 4 card ♥ suit. You plan to bid 2NT (11-12) next go unless partner bids ♥'s in which case you raise. |
| |
|
| |
(b) |
1NT, 11-13 with quite possibly a 4 card ♥ suit. |
| |
|
Note that you cannot use the same ploy of bidding a minor suit as that is non-forcing opposite an overcall and a 2♣ bid may get you too high anyway. |
| |
|
|
|
|
| |
Note that if partner's overcall is at the two level (not a weak jump) then he presumably has close to opening values and the No Trump responses are approximately : - |
