Opening Leads (Part 1)

More than half the time, selecting the correct opening lead will make or break the contract. Put another way, most contracts make at least one overtrick because of faulty leads and defense. What’s the easiest way to pick up your game? Learn a few simple rules about opening leads and adhere to them. Note that I didn’t say anything about memorizing the exhaustive opening lead tables that are so common, nor did I imply you needed to be a genius. As quixotic as experts would like to make this, there is a process that will enable your partnership to function efficiently and score better. First you must determine the suit to be lead. Second, and more important, is that you must determine the card to be led in the suit you have selected. Your choice of card will tell partner about your length and strength in the suit.

You are not left to guessing as there are standard lead disciplines that have been developed over time. If you want to be more successful in selecting the right card, just follow 6 simple rules:
1. Lead the highest ranking card from touching honors except lead the King from AKx(x)(x) and the Ace from AK doubleton. (See later discussion).
2. Lead the Second highest card from a broken sequence such as KQTx or KJTx.
3. Lead the 4th best card from a 4+ card suit headed by an honor.
4. Lead the highest card from three small cards (see later discussion).
5. Lead the lowest card from 3 cards to an honor (see later discussion).
6. Lead high from any doubleton.

Let me emphasize that these are standard leads, and partners can choose to make non-standard leads as long as the variance is fairly disclosed to the opponents. Marking the change on the convention card will do. The most common exception to standard leads today is the lead of an Ace from AKx+ and lead King from Ace King doubleton. Don’t ask me why, I don’t understand it, but if that is what your partner wants to do, just humor him. There is also a thriving controversy about what card to lead from 3 small cards. While many stay with the standard and lead the highest card, an equal number lead the lowest card. If that is not bad enough, some partnerships use MUD, middle card, then up and then down. Here briefly are the considerations.

When you lead the top card from three small it is impossible for partner to know if you hold 2 or 3 small cards in the suit. The trade off is that he knows that you do not have a card higher than the card lead. Guess what, so does the opposition! When you lead the small card from 3 small cards, partner will know that you do not have a doubleton, but he will be uncertain about whether you have an honor in the suit since you also lead small from three or four to an honor. In an effort to side step this uncertainty (and add even more uncertainty), some partnerships use MUD, but the downside about this is that you do not know whether it is from a doubleton or three cards until the second card is played. You also forfeit the discipline of the lead of a low card (5 or under) guaranteeing an honor in the suit. Each has their own supporters and none is perfect all the time. You and partner need to decide what to do and mark your card if it is not “top of nothing.”

If partner has bid a suit, you are hopefully going to lead it. If it turns out to be a rotten lead, get a new partner. Who asked him to overcall on KJxxx? Lead low from 3 cards and high from two cards to give partner a count in is suit. There are variations on this scheme as well, but this basic rule will work.

If partner doubles a conventional bid by opponents, this means he wants you to lead that suit. This opportunity often happens on Stayman and Transfer bids in no trump bidding. What if partner doesn’t double a conventional bid? As usual, there are strong inferences to be taken from silence, and in this case lead any suit other than the conventional bid he did not double. Here you may have to woodshed partner to train him to do the right thing.

If partner makes a takeout double, it usually means he has something in the other three suits. If you are on lead and have an honor in any of the unbid suits, lead that suit as it is reasonable to assume that partner will be able to help you out with a supporting honor. That gets you off to an aggressive start. If you have a hopeless hand without any defensive possibilities, and you lead any of the three unbid suits, you likely will finesse one of partners honors. Make declarer figure it out and work for it. Now is the time for a passive lead like trump.

With the next post we will cover leading at no trump contracts. Following that I will cover leads at suit contracts, then trump leads and leading against slams. If you want a reference work for definitive information on opening leads and the play of the hand I recommend Easley Blackwood’s The Complete Book of Opening Leads (1983) or the all time classic, Louis Watson’s The Play of the Hand at Bridge (1933). Both are good references, but a substantial workout to read cover to cover. Just rereading the six rules and getting on the same page with partner may produce quicker results.

Michaels Cue Bids Revisited

After Stayman, Blackwood and Transfers, Michaels Cue Bids and Unusual No Trump are probably the most common conventions. They are used by most rubber bridge players, and have now become part of the consensus Standard American Yellow Card system (SAYC) as well as more advanced systems. Today I’m going to focus on Michaels Cue Bids developed by well known professional, Mike Michaels. In yesteryear, an immediate cue bid after an opening by opponents showed a monster hand and was forcing to game. Since today we can first make a take out double and then bid to show an unbalanced hand in the 17+ range, or overcall 1NT or 2NT to show big balanced hands, the cue bid has been recruited to show hands that have 5-5 distribution.

While some partnerships may permit a Michaels bid to be made on a 5-4 hand, I prefer sticking with the original concept of 5-5, even when it involves both majors. If you want to change Michaels to some combination of 5-4, you definitely need to discuss it with your partner. The risk is with equal support, partner may take a preference for your 4 card suit and you end up singing the wrong song.

With 5-4 distribution and a hand worth an overcall, I would recommend overcalling your 5 card suit, and if it does not misrepresent your hand strength, show the 4 card suit on the second bid. It is convenient to do when your 5 card suit is the higher ranking suit and your 4 card suit is lower ranking, since then you can give partner a simple preference without reversing the bidding. The thing to avoid is reversing the bidding on a modest hand. If your 5 card suit is lower ranking than your 4 card suit, you just have to eat the four card suit. This may be the justification for permitting 5-4 Michaels, and would work best if limited to five hearts and four spades.

Let’s get the bids out of the way:
(a) a cue bid in a minor (1c/2c or 1d/2d) shows both major suits.
(b) a cue bid in hearts (1h/2h) shows 5 spades and an undisclosed 5 card minor suit.
(c) a cue bid in spades (1s/2s) shows 5 hearts and an undisclosed 5 card minor suit.

The traditional strength requirement to make a minor suit cue bid (showing both majors) is 7+ hpcs. If the cue bid shows a major and minor, I would raise the requirement to about 10+ hcps, since you often end up at the three level playing a minor suit. You must watch the vulnerability and adjust your strength up or down. With equal or favorable vulnerability, I might substantially lower those requirements. With unfavorable vulnerability, I would be at the top. The most important thing is that you have the majority of your points in your two 5 card suits. Singleton or doubleton honors in your short suits are often worthless.

Here are the responses:

(a) If the cue bid is a minor (showing majors) a simple response to the 2 level in a major can be made on weak hands if you have 3+ card support. It is not a constructive bid. A direct raise to the 3 level is generally regarded as invitational with 3 or 4 trump. "Invitational" in this sequencing surely means a hand you would have opened had partner not made a cue bid. A bid of 2NT shows a balanced hand, stoppers in the minors and opening no trump values (15-17). A cue bid by advancer (1c/2c/p/3c) is a game force. You have a very good hand and plan to get a new partner if this one stops bidding short of game.

(b) If the cue bid is a major (showing the opposite major and a minor) and you have support for the major suit indicated, the responses are essentially the same as shown in (a) above. If you do not have support for the major (singleton or doubleton) and have at least 3 card support for both minors, you can ask partner to show his minor by bidding 2NT. When partner shows his minor, you can then decide how to proceed using “judgment.” (We never seem to be able to abandon that word, do we?)

Often partner’s Michaels bid will set the stage for a sacrifice. If the bidding goes 1h/2h/4h/?, it does not sound good for the home team. If you have exceptional support for spades (4+ cards) or if you have great minor suits, you may want to make a save. In spades you would simply bid 4 spades. If you have great support for the minors and little defense, you may want to save in a partner’s minor. You bid 4NT asking partner to bid 5 of his minor. Your hand may look like xx, xx, KJxxx, xxxx. If partner has as much as AQxxx, x, Qxxxx, xx, you may be able to hold it to down 2. In match points this strategy can be very effective, as opponents heart game looks pretty solid. At IMPs, 5 level saves are much more problematical, and running up the white flag is most often the best.

You may have heard of “over/under Michael’s.” In this scheme, with 5-5 hands you use Michaels with hands in the 8-10 range and with hands over 16 hcps. If the hand falls in the middle with 11-15 points, you attempt to bid both suits and forgo Michaels. This attempt at showing the size of the 5-5 hand is just a bunch of crap a far as I am concerned. With 11-15 hcps, you often do not have the bidding room to show both suits and your story never gets told. Most good players today realize the importance of showing the distribution of the hand as soon as possible by playing what I have earlier described, known as “Continuous Michaels.”

In Frank Stewart’s bridge column last Sunday he showed a world class Norwegian pair at work. Geir Helgemo sitting south held KJTxx, KJTxx, xx, x. East opened the bidding one club. For whatever reason, Geir bid 1 spade thinking he would bid hearts next to describe this hand. The bidding went 1c/1s/2s (limit raise or better for clubs)/3s (weak preemptive raise)/ 3NT/4 h/p/4s/x. Well, he finally got to describe his hand, but he was at the 4 level before the opportunity presented itself. What is wrong with a Michaels Cue bid of 2 clubs to describe the hand. It puts partner in the picture instantly and lets him be the “captain of the ship.” The only downside I can see is that it would have deprived Geir of the opportunity of going -1100 and the loss of 15 IMP’s.

A final caution. I had a hand last Friday where my LHO made a 2 club cue bid over my one club opener. We ultimately prevailed and played a game contract in a minor suit. The trump broke 4-1, but I was able to pick up the entire trump suit with Kxxx in east’s hand. The Michaels Cue bid told me that my LHO opponent had only 3 minor suit cards and that the outstanding major suit honors were likely to my left. The play of the hand was somewhat contorted, but fully justified by the information I had been gratuitously given. Michaels Cue bids and Unusual No trump always give opponents information. Be sure it is worth the price!
