Mixed Raise Response to Overcalls

I hate to write about the history of bridge bidding, since it is rarely is germane, but on this topic it may help you understand where we are heading today and why. Since in Bridge, my actual history does not extend into the 20th century, I may be a poor one to write this, but my hearsay sources are good.

Back when cards were still shuffled, responding to partner’s overcalls with supportive hands was quite simple. They actually resembled the responses you would make to opening bids, so life was much easier. If you had 3+ card support and 6-9 hcps you raised partner’s overcall. If you had the same hand with limit raise values you jumped in his suit. If you bid a new suit, it was forcing one round. If you bid 1NT, you took the smile off partner’s face. Well, that part never changes.

That all worked well “back in the day”, so why make any changes. Here are my own observations. At that time, overcalls were really overcalls, you could actually lead partner’s overcalled suit and not give up a trick on defense! One level overcalls were expected to have at least 10 hcps, 5+ cards in length and a good suit with honor strength. Even a “space eater” like 1d/2c was expected to be an opening hand equivalent and probably a one loser suit. A 1NT overcall showed at least 16+ hcps and a double stop in opponent’s bid suit, and jump overcalls were as strong as overcooked morning coffee, you could take them to the bank for direct deposit. In that environment simple tools for searching for games worked well because overcalls were so disciplined. Actually, in the overcall seat “trap passing” with a big hand was a prominent strategy, and lead to light third seat openers.

The first development was “Sputnik.” If you know what Sputnik is in bridge terminology, it’s well past the time to give up the game. No, I am not referring to the Russian satellite, it’s actually the system we call "negative doubles" today. Alvin Roth invented it and claimed that it was the beginning of the space age of bridge. He was not too far from wrong, and many of his ideas form the basis for the 5 card major system we play today. As a result of Sputnik, everybody gave up their penalty doubles of overcalls (the primary policeman of sloppy overcalls) and joined the space age. At this point the pent up frustration of not being able to overcall on "pure crap" broke loose!! Overcalls started down the slippery slope and we may not have seen it all yet.

As overcalls got less disciplined (more diverse as my partners prefer to say) it became more important for advancer to be able to better describe the shape and strength of his hand to put overcaller in the driver’s seat. If advancer can precisely describe his hand, then overcaller can call the “shot”: Go or No Go.

A further development was the popularization of the “Law of Total Tricks.” Although Marty Bergen and Larry Cohen did not develop the theory, they put it on every bridge player’s menu. No longer did 1c/1s/p/3s mean a limit raise, it meant that we had 9 trump between us and a hand not good enough for a limit raise. The sequence 1c/1s/2c/2s no longer guaranteed anything other than 3 card support for spades. Since the LOTT changed the jump raise to make it preemptive, the cue bid in opener’s suit was put in play to show a limit raise or better with support. This is where most of my readers find themselves today.

It bothered bridge theoreticians that the Law of Total Tricks would have you raising a 1 spade overcall to three spades with QJxx, xx, xxxx, xxx and also raising to 3 spades on QJxx, xx KQxx, xxx. The first hand is clearly preemptive, but the second hand has some very constructive values as a supporting hand. Enter the Mixed Raise which I first read about in Larry Cohen’s “To Bid or Not to Bid-The Law of Total Tricks”. The Mixed Raise in competition is shown by a jump cue bid on the 3 level. So, 1c/1s/p/3c shows the Mixed Raise.

The first two requisites of the Mixed Raise are 4 card trump support and at least one doubleton. The more distribution the better, do not use it on 4333 hands. The final issue is points. Since the Mixed Raise is by definition less than a limit raise (which remains a simple cue bid) I prefer 7 to 9 support points. Examples might be 7654, A987, 6, QT87 and QJ98, A5, JT42, 763. Since partner did not double and then overcall, he could have as much as 16-17 hcps for his overcall. The jump cue bid is self alerting. If partner passes your cue bid, you know what to do. If partner just bids 3 spades, that shows no game interest. If partner bids game, well “you done good.”Pray he declares well.

With the uncertainties of overcalls in today’s competitive bidding, it becomes important to “slice and dice” advancer’s hand to define it as tightly as possible. Talk this over with your partner and add it to your arsenal. Even if partner gets confused and can’t remember what the double cue bid means, it has to be supportive and he has to bid something, so hopefully he will rebid spades and this will not end up in a bidding disaster. With 4 trump you wanted to compete to the 3 level anyway.

A Playing rule -- Everybody Loves Playing Rules

I hate to divert my energies from competitive bidding. We'll be back to that topic shortly. But speaking of competitive bidding, I was just reading Mike Lawrence’s 2009 rewrite of his legendary book, The Complete Book on Overcalls. This revision has been 30 years in coming, but it was long overdue. Mike was always an advocate of very disciplined overcalls, and very slow to change his mind about principles that had worked for him 30 years ago. His new revision does make some concessions to the need to compete in matchpoints, but he stops short of jumping on the Bergen-Cohen bandwagon.

The rewrite is a good and necessary one and will reestablish the book to it’s former prominence. But do you think his heart was really in this project? Here’s a quote from page 16:

“Good matchpoints is almost never good bridge. You have to learn to play badly. Things that are theoretically wrong, at matchpoints work a high percentage of the time.” Gee Mike. I’ve been saying that for some time now, you reading my blog?

Now for a little dancing music. In the heat of battle, as declarer it is frequently difficult to figure out the best way of playing card combinations. You are counting cards, counting points, reviewing the bidding and calculating the odds, my gosh, even back in the old law office they gave us yellow pads. There are so many Mnemonic (thank God for spellcheckers) assists in the bridge universe that Ron Klinger wrote an entire book about them in 1998 titled Better Bridge with a Better Memory – How Mnemonics Will Improve Your Game. According to my count there are Bridge Rules numbered from 1 to 23. Since you already know the Rule of 11, let’s start with the Rule of 12.

The Rule of 12 is a rule that you can put into play immediately. Hardly a hand goes by that you do not have to make some decision about finessing. How many times have you had a finessing layout, and wondered if it is safe to start the finesse by playing a high card, (often a Ten or Jack) and letting it ride or whether it is prudent to start with a low card and re-enter. Well if there wasn’t risk, we wouldn’t give it another though; who likes to burn entries getting back to take the finesse a second time, or worse yet, have your re-entry trumped by opponents.

Assume you are declarer and you in the dummy ready to finesse:

*****QTxx

*****AJ64
Also assume you have one more dummy entry, but you would rather not use it at this time. Is it safe to play the Q, and if successful, play a small card to the Jack or is there risk in that line of play?

Rule of 12 to the rescue. Here is the Rule: Add the cards you hold in the suit and to the number of cards in both hands that are sequential and if they equal 12 then it is safe to start with the high card. If not, there is some risk associated with starting with the high card.

In the above case we have 8 total cards in the suit and 3 sequential cards so we fail to meet the Rule of 12. What is the risk? Suppose I show you the rest of the suit.

*****QT52
9876 *******K
*****AJ43
The 9 promotes to a trick if you start with the Queen or Ten. Note that if I give dummy the 9 and put the 5 in West’s hand, we would meet the rule of 12 and it would be safe to roll the Queen.

Is this distribution probable? Not probable but possible, and when it makes a difference and you play it correctly it is guaranteed a good board. Many players just play the higher card hoping for the best.

The rule works in the same way whether the suit is 7, 8 9 or 10 cards in length. Add to the length of the suit the number of sequential cards. Do they equal 12? If the suit is AJT3 opposite Q92, lead the 2. If the short holding is Q98 lead any card, your total is 12.

What if you don’t have an entry back to the dummy? Lead the top card and hope this is not a computer hand.

Table of Contents for Tommy's Bridge Blog

In the past 5 years I have posted to my Bridge Blog about 115 times. It started out as sort of a joke among my bridge friends and just grew from there. The blog was a personal outlet for my life passions; research, writing, learning and teaching. It was a shock to me that I was accumulating readers not only from North America, but other parts of the World as well. I would like to say that some of them were experts, but alas, only a few, and most readers were struggling to make headway just like me. When my counter was working, I was getting about 100 hits a week, not what you would call a commercial success. My archived blogs have always been a workout to find. I never did anything about it since some of my early posts are best forgotten and having them conveniently buried in a difficult process seemed a blessing. What they can't find they can't criticize!

One of my early readers was Jim Logsden from Texas. Even though I have never met Jim, he has read every one of my blog posts and actually created a table of contents or index for his own reference. Jim recently surprised me by sending me his table of contents. It is an impressive job and it occurred to me that it might be useful to to other readers, so I am posting his table of contents. Now about assembling these into a book ---- not a chance! You can stop worrying about any further proliferation of my little musings and meanderings.Think about it as my major contribution to better bridge.

Scrambling Two No Trump

Scrambling 2NT is a tool for taking risk out of balancing and pre-balancing (making a double in the direct seat). The bid is conventional and has nothing to do with playing any level of no trump. One of the fears of balancing is that when you double as a balance or pre-balance, partner will bid one of his 4 card suits and it will turn out to be one of your 3 card suits. Now, I would rather play a 7 card trump suit than let opponents play 2 of a major with a fit, but not if it is not necessary.

Let’s set the stage in the “classic” balancing auction: The bidding goes 1s/p/2s/p/p/X/p/? The good news is that “trusty partner” has balanced and they are not playing 2 spades. The bad news is that it is your turn to bid. Suppose you hold xx, Axxx, Kxxx, Qxx. Since hearts is the major, many players are just going to bid 3 hearts and hope. The minute you do that partner will hold xxx, Kxx, QJxx, Axxx. Some may decide to bid their 4 card suits up the line and hope for a fit in diamonds. The minute you do that partner will have a hand like xxx, KJxx, QJx, Axx. Yes, you could fall into an 8 card trump suit if doubler’s hands were reversed, but bridge is, by and large, a perverse game and justice is rarely served. There must be a better way!

Enter Scrambling 2NT. The Scrambling 2NT bid is used after partner makes a double in the direct or balancing seat and you hold two 4 card suits. The bid of 2NT is designed to find an 8 card fit. It asks doubler to bid his 4 card suit or if more than one to bid them up the line. In my first example, after 1s/p/2s/p/p/X/p/2NT, doubler will bid his 4 card diamond suit and we will play 3 diamonds. In the second example, doubler will bid his 4 card heart suit and we will play 3 hearts. Yes, if doubler has four hearts and four diamonds, we will be playing our diamond fit rather than our heart fit. Forget about it! Our objective is to jolt opponents out of their 2 level spade fit and find an 8 card fit of our own at the 3 level. Put greed behind you and take the guarantee. Your master point profile will appreciate it.

Let’s spin it around and look at it in a pre-balance format. This time the bidding goes 1s/p/2s/X/p/?. You hold Kxx, xxx, Kxxx, Kxx. Note again the 2 four card suits, with a random chance of making the correct choice. Here again bid Scrambling 2NT to search for a 4-4 fit. If doubler in the direct seat has xx, Axx, AQxx, Qxxx, he will bid his 4 card club suit up the line to start the scramble. Since you do not have 4 clubs, you bid 3 diamonds showing your four card diamond suit, and hopefully we play it there in our 8 card fit. We may go down one, but in balancing that is pure gold. For sure we aren’t going -110 or worse.

Note that in each of these examples doubler’s partner does not have a 5 card suit. In fact, if he has have a 5 card suit he must bid it and not use Scrambling 2NT. Scrambling 2NT has a good negative inference. When we scramble we are either 4333, 4432 or on very rare occasions 4441. Helpful information in either the bidding or the defense. Since partner's square hand will not play as well as a distributional hand, you may want to think twice before competing further.

I can’t believe that I have gotten this far and nobody has pointed out to me that we have given away the natural bid of 2NT. Why would b we ever want to play no trump when they have found an 8+ card fit and will be on lead. Hopefully, this idea makes no sense to you as well. Nirvana, we have found a vacant bid and put it to good use.

The Scrambling 2NT bid is alertable. Just say that partner is asking me to further define my hand looking for a fit. This is not overly complicated. Think of the Scrambling 2NT as being like a responsive double. You are passing the bid back to partner to make a choice since your choice is not clear. One of the major benefits of the bid is that it will enable your partnership to make more aggressive doubles knowing that you can find your 4-4 fits safely. Yikes, if I balance any quicker I will be out of tempo.

Talk this over with partner in advance, not while the director is passing out the boards. It takes a moment to digest, but with minimum thought it pretty much sells itself.

This is my last post from Rochester, New York. On October 13 Axel, Virgil, Alla and I fly to Florida for the winter. Axel and Virgil are my two cats who do my proof reading. Looks like it doesn’t it. Rochester is a wonderful bridge town and I will miss my many friends who have made me feel so much at home. I look forward to seeing all my old bridge buddies in Citrus County, Florida. I can only hope that majority of them feel the same way.
