Thoughts on reopening the bidding with a balancing double

Situation: You open the bidding one of a suit in 1st or 2nd seat, left hand opponent makes a suit overcall, partner passes, and right hand opponent passes. Notice that partner did not make a negative double. Do you keep the auction open and, if so, how?

Marty Bergen has guidance for us in this situation.  I will summarize his guidance below, but first look at two hands I recently observed. For each of them would you bid, pass, or make a reopening double?

Hand 1:

 

Hand 2:

What did you decide?

 

Here is Marty’s guidance:

Doubling in this situation is not “automatic” as some players seem to think. The main consideration is your holding in opponent’s suit.

  • Void: It’s rarely the case that you should double. Defending with a trump void is usually not correct. I was surprised to read this guidance. But on reflection “law of total tricks” may work in opponents favor on average, so our side may get a better score on offense than by defending. What do you think?

  • Singleton: Usually the ideal time to double.

  • Doubleton: Good time to double an overcall at a low level.

  • Three cards: Try to avoid making a double.

  • Four or more: Never make a reopening double.

Post mortem on the two hands:

  • Hand 1: South made the reopening double, partner bid two hearts, and South ran to three diamonds resulting in plus 130 for above average board.

  • Hand 2: South chose to rebid three clubs holding 10 cards in the rounded suits. A reopenng double would have resulted in 1100 points for NS. North had the ideal “trap pass”, and the partnership missed the opportunity for a top board.

Another on Counting your Losers

You opened one heart in 2nd seat and West overcalled two diamonds. Partner had enough strength to make a negative double at the two level. Having 5-5 in the rounded suits increased the value of your hand. So, you were willing to go to three clubs for your rebid. Partner took the suit preference for hearts and you bid game. Opening lead was the king of diamonds.

 

Here is what you saw summary of the bidding:

You were in a good contract. How would you play to make four hearts? Your thoughts on opening lead:

  • West should have the ace of hearts.
  • Other than that you have the remaining high hearts.
  • You have the top three clubs, and there is a good chance they will split no worse than 4-2 (84%).
  • You should lose no more than two spades and the ace of hearts.
  • Hearts should split no worse than 4-2 (84%).

Do those clues shed light on how you should play? Please let me know by email or in comments if you are unclear on what to do at trick two.

Learning from our Errors

A particularly useful aspect of playing on BBO is the ability to assess errors quickly via post mortem discussion with partner. Here is a hand I thought I had misplayed, and I knew an expert had been in the field sitting in my seat (East). It would be easy for me to see how the expert had played this hand:

BBO misbid

Both vulnerable, my partner opened one club in 1st seat. North overcalled one heart. With eight points, three spades and a partial heart stopper I decided to respond one no trump. That’s where the bidding ended.

South led the nine of hearts and this is the dummy I saw:

BBO misbid1

I was happy to see the nine of hearts, knowing I now had a sure heart stopper. North took three rounds of hearts. But rather than giving me my sure stopper in hearts, he shifted to a low diamond. I correctly recognized that I had a sure stopper in diamonds since dummy had the nine and eight. So, I played low from hand. The rest of it went quickly. And when the dust settled, I was down three for a bottom board. Do you see where I went wrong? What did the expert do that was different? Give it some thought and then scroll down for my evaluation.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

What did North do that was different? Answer was easy: East passed at his first turn. It was a negative double situation, and he had a heart stack. There was no reason for him, with eight points, to come into the auction. We bridge players tend to be too aggressive at times, and that was my blunder. No reason not to be patient, partner still has another turn.  The huge error on my part was bidding.

 

BTW, I did misplay the hand, too. I could have salvaged a matchpoint by putting up the king of diamonds at trick four. ☹

 

A Bidding Judgment Problem

Posted on by 3 comments

See update below

Here is a bidding problem that I got wrong recently:

MikeL16

What would you do after the auction shown? I failed to exercise my visualization skill. What is partner doing? Why is she bidding hearts after making the negative double? How big is her hand? Can you you make a better decision than I did? Let me know in the comments.

Update 6/2/2020:

Partner would have responded 3 hearts rather than making the negative double at her 1st turn. The negative double should have told me she is near to a game forcing hand or better. The three heart bid at 2nd turn suggests she has game forcing values and is looking for me to bid 3NT with a club stopper. Having none, I should bid out my pattern by making the rebid of four diamonds. Parter’s strengh must be in diamonds and hearts, and she she should have fewer than three spades with an honor. Here is the entire hand:

Planning your Rebid

Posted on by 0 comment

Here is a common situation. You have a minimum opening hand, so you must plan a rebid that does not get the auction too high should partner respond one spade.

rebid3

I recommend opening one diamond, planning to make a comfortable rebid of two clubs. That distorts partner’s image of your shape, but she will clearly know that your opening bid was minimum.

You may want to change that plan if opponents interfere. For example, say your left-hand opponent overcalls one heart, and your partner responds one spade. Since your partner did not make a negative double, you know she has at least five spades (double would promise exactly four spades). In that situation I recommend you switch your rebid to 1NT. Partner will know that you have fewer than three spades. And even though your spade is singleton, it sure is a nice one!

Negative Double

In this case your partner opens the bidding with one diamond. Right hand opponent overcalls one heart, You hold:

neg dbl2

You have just enought strength to make a negative double with bidding still at the one level. Double by you says to partner that you hold exactly four spades and 6+points. If you held 5+ spades you would instead bid one spade.

Negative Double

Here is a hand from yesterday that displayed the negative double in action.

neg dbl

Your partner opens one diamond in second seat. Right hand opponent overcalls one spade. You have some nice values, four hearts and six clubs. It’s perfect situation for a negative double. Double promises four plus hearts in this situation. Your partner will know what to do. Most pairs yesterday got to game and made five hearts.

Action When Opponents Overcall?

Hint: I hope you did not raise clubs or bid two hearts!

Handling Interference

Update Below

Lot’s of interesting hands in today’s Unit Game. Here is one for you:

unit1

You are in 4th seat (favorable vul), and your partner opens one diamond. RHO overcalls two spades. What is your call?

First, how good is your hand in context of the auction so far? Singleton spade is a nice feature. You have three card support for partner’s suit, including two honors. You have five clubs, including King-Queen touching honors. I suggest it’s worth 11 or 12 points. Don’t you think you should bid? If so, what’s your call?

My recommendation tomorrow.

My recommendation: This is a perfect hand for a negative double. You promise at least four hearts and have clubs. Also, you would be happy if partner rebids her diamond suit.

Allan on two interesting hands

The first is board 1 from Wednesday the 14th:

bd1 Wed 8 14

Allan commented:

Board 1.  Assume bidding starts 1D 2C .  How does south express his holding?  Be aware that direct 2S is strong and forcing 1R.  Negative X and intending 2S seems suitable; if (west passes and) opener rebids 2D, then what? If west raises to 3C and south becomes balancer, then what?  [Note – negative free bids allows initial 2S by south.]

My comment: South has 10+ points in context of the auction so far. Why shouldn’t South respond 2S? South’s hand looks strong enough to me.(I don’t usually don’t play negative free bids.) Maybe I need a stronger hand to make a 2 over 1 response when my suit is higher ranking than the one partner opened? Any thoughts from the thousands of awesome bridge players reading this?

The second is board 8 from Wednesday the 14th:

bd1 Wed 8 14b

Allan asks:

Assume P 1C X P / 1H .  North’s next call is either P or 2C.  How vigorously does E raise hearts?

What do you think? I would bid 3H in response to East’s take out double. With 5 hearts to the J 10 8, ace of spades, and singleton club it looks like 9 support points.

I held the East hand and chose to bid 2H rather then double at my first opportunity. NT looks out of the question because of East’s awful holding in clubs. I thought the smallest lie was 2H with the top three honors (so good it looked like a 5-card suit to me). We did not have any trouble reaching 4 hearts once my partner raised me.

 

 

 

Let’s Get Rolling! August 7th Bridge Lesson Recap

Posted on by 0 comment

Aloha, Bridge Players!

I’ve just returned from the American Contract Bridge League (ACBL) Summer Bridge Championship in Las Vegas. I completed the educational requirements to be considered a qualified bridge teacher, and now I’m back to teaching my weekly class at the Hilo Bridge Club (HBC) which I’ll be recapping here on the HBC blog. So let’s get rolling!

Today we’ll have two exercises based on last Wednesday’s class, and tomorrow we’ll have two more.

Exercise 1: It’s Your Call. The bidding so far: ;

20190807-01a

You are South holding:

20190807-02

What is your bid? Think of your answer before scrolling down to see the answer.

 

 

 

 

This is an exercise in recognizing a negative double situation. You have 7 points in context of the auction so far (the overcall promotes your K♠ and you have touching honors in clubs). Make the negative double in hopes of finding a 4-4 heart fit.

Exercise 2: It’s Your Call. The bidding so far.

20190807-03a

 

You are South holding:

20190807-04

What is your bid? Think of your answer before scrolling down.

 

 

 

 

 

 

 

You have a nice hand in the context of the bidding so far. Your spade holding behind the opener is worth more than 6 points. You have touching honors in the club suit. This hand is worth an opening bid. But is it worth an overcall? I would overcall 2♣. Some may prefer a better club suit and would decide to pass.

Do not make a takeout double! Takeout double implies that you have at least 4 hearts and shortness in spades. And your hand is not big enough to double and then bid clubs.

See you tomorrow for two more exercises!
