Lesson 3G Main


Overcalls


 by Richard Pavlicek

The opponents will open the bidding ahead of you about half the time, so it is important to have an effective defensive bidding structure. You and partner must be confident in the meanings of each other’s bids.

This lesson applies when an opponent opens the bidding with one of a suit — by far the most common opening bid — and you enter the bidding with a direct overcall.

One Level Suit Overcalls

An overcall at the one level serves a variety of purposes: It tells partner what to lead; it is a general nuisance to the opponents; and it may be the start of a constructive sequence by you and partner.

A one-level suit overcall shows 10-18 points and a 5+ card suit.

With only 10-12 points suit should be at least Q-J-x-x-x. With 13-18 points
a 4 card suit (at least K-Q-J-x) is OK if no other action is appropriate.

Partner should respond at the cheapest level with 8-11 points.

The 2 C response is nonforcing and it denies spade support (else West should raise spades). East is not delighted but he should not rebid 2 S without six cards.

Invitational Responses

If you have more than 11 points after partner overcalls, game is on the horizon.

With 12 to 14 points you should usually make a jump response. This is invitational to game but nonforcing.

Lebanese Lesson

There once was a man from Beirut
Who thought he would try to be cute.
 He overcalled a spade
 And died as he played.
The postmortem: a four-card suit!

Game-Going Responses

If your hand contains 15+ points, you may bid game directly if you are sure of the best contract. If you need to explore, remember that new suits and jumps are nonforcing.

A cue-bid of the enemy suit is the only forcing response.

West has the strength to bid 3 NT over 1 H, but this may not be the right contract so he cue-bids the enemy suit. East rebids naturally to show his diamond stopper, and this resolves any doubt for West.

Lesson 3G MainTop Overcalls

Two Level Suit Overcalls

It is more dangerous to overcall at the two level, and it should not be done on hands of 10-12 points — sometimes you just have to pass.

A two-level suit overcall shows 13-18 points and a 5+ card suit.

Avoid overcalling at the two level with 13-15 points and a poor suit, especially vulnerable. This often leads to trouble.

Partner should respond at the cheapest level with 8-11 points.

Jump Suit Overcalls

A direct suit overcall that jumps the bidding is a weak bid.

A jump overcall of 2 D, 2 H or 2 S is like a weak two-bid. A bid of 3 C or higher is like a preemptive opening bid.

Partner should respond as he would to the same opening bid.

One Notrump Overcall

An overcall of 1 NT is the same as an opening bid of 1 NT although it requires a stopper in the enemy suit.

An overcall of 1 NT shows 16 to 18 HCP and a balanced hand.

Optionally, you may include hands of 15 HCP. Then the range is 15-18.

Partner should respond as he would to a 1 NT opening bid.

Two Notrump Overcall

A direct jump overcall of 2 NT is nothing like a 2 NT opening bid. It is the “unusual notrump.”

An overcall of 2 NT shows 10+ points with at least 5-5 shape in the two lowest unbid suits.

Another way to show a two-suiter is the Michaels cue-bid (not covered in this lesson but highly recommended).

Partner should choose between the suits shown.

Three Notrump Overcall

An overcall of 3 NT shows 16 to 20 HCP, a strong 6+ card minor and a stopper in the enemy suit.

East is simply bidding what he expects to make (with a heart lead). It is acceptable to have an unbid suit unprotected.
