****How to Deal with Interference After Partner Opens 1N******
Frankly, when partner opens 1N and the opponents interfere, this is an irritating situation. It is less so if we know what to do, but still a pain. Some bids and some methods are worse than others but we need to learn how to deal with this. Some background first.
At matchpoints, there are some players who just dive in, all the time. They do this on 4-4 patterns, all kinds of crazy stuff. On one hand, they are risking huge numbers, but on the other hand, they can get huge payoffs by messing up the bidding. Matchpoints is a knife fight in a dark room. If you are playing IMP pairs or teams, the risk/reward isn't nearly so great for the "scramblers"...they have a lot better chance to be handed their head. You can apply the methods below but if you know your are playing against matchpoint oriented loonies, just keep your doubler out.
Interference bids in sane situations are usually on lengthy one suiters or serious two suiters. Most people adopt one of the common methods and use it. You ought to know how to counter these bids. It is helpful to have some tools to work with before starting discussions on countering specific methods. The first tool you need to have is Lebensohl. This is, as far as I know, the best tool to use to counter 1suiters. You also need to think about playing neg x's over 1 suiters. In general, it is not productive to play immediate x's of one suited bids as penalty, regardless of what we were taught when we started playing bridge. For sure, look up Lebensohl, learn how to play it. It is hugely useful in this situation and even more so dealing with weak two bids. If you don't play it over weak two bids, aggressive weak two bidders will drive you nuts.
Before we discuss how to beat the methods, let's see what the strengths and weaknesses are.
Capp is the "default", it seems on BBO. On one hand it is a programmed way to get into the bidding on both one suiters and two suiters. With all due respect to Mike Cappelletti and Freddy Hamilton, I sincerely believe it has a theoretical weakness. In theory, a bid over an opening nt has a fairly high degree of risk. Their responder knows opener is on a lot of points and has a flat hand, more or less. If you walked in when you are unlucky, you can just get killed. So what are you trying to accomplish with a bid here? Theory again, you should have two objectives..one, to compete for the part score, and two, to throw a monkey wrench in their well-ordered offensive bidding machinery. The second is getting more important all the time. People, even rookies, are bidding so well that leaving them alone and letting them use their tools, is getting expensive. So, perhaps you need to be bidding, and having a schematic is a good idea. The only problem is, Capp does a poor job of getting in their face. Why? Because the one-suiter of Capp doesnt' cause any pain. Any bidding over 1n should have two qualities, one, it is major oriented, exclusively, and any 1 suiter should make 3rd hand's life difficult. Why so much emphasis on majors? Because if you have minor orientation, and bid, you shove them out of nt and into a major where they belong, and worse if you both have fits, they can outbid you....maybe you ought to defend nt when you have minors?????
CAPP (Short for Cappelletti...and also called Hamilton...two claims on inventing this, I think)
X is penalty
2c is a one suiter
2D is both majors
2H is Hearts and a minor
2S is Spades and a minor
2N is both minors
To deal with this:
Over X:
XX to relay to 2c, and pass with clubs, or correct to D.
From here "all systems on"...stayman and transfers..but I recommend that 2S is a double minor takeout, weak
Over 2C...the biggest weakness of their system...
X is Stayman...commonly called "stolen" for "He stole my bid"
again, "all systems on" but now, 2S is your normal stuff, Minor Suit Stayman or 4 way transfers
Over 2D(Majors)
You now know both suits...if you have interest in penalizing them, X
if you have both minors, but no interest in game, pass, let them pick a major and bid 2N at your next turn (2N is not a good place to play partscores...use it in competitive auctions for takeout).
Q bid a major if you have a stop and a game going hand. Your most likely game is 3N. If you have a game going hand in one minor, Q bid either major, preferably one with a control and over partner's next bid, bid your minor. With both minors, game going, no interest in 3N, Q the preferred major, and over partnters' next bid, Q bid again.
bid either minor to play
Over 2H or 2S(that major and an unknown minor)
Use Lebensohl. It's hard to deal with an unknown suit, ignore it.
The most common bid from Capp is the one suiter. The 2C bid accomplishes nothing as far as making you work if you play what is outlined above. A better tool is called for for them, but now you can deal with Capp. (A better tool is outlined below)
DONT:
Another fairly common schematic for bidding over nt, and another one that has a lot of minor emphasis (thus wrong).
X=a one suiter (No, no penalty double...sigh)
2C=Clubs and a major(oh, wonderful, let's bid them clubbies)
2d=Diamonds and a major(see comment above)
2h=Majors
2s=a better spade one suiter
2n=both minors
The theory weakness is even worse...x doesn't do any "preemptive" work at all. The only thing to be said for DONT is that it keeps you at the 2 level on all two suiters but minors. If you are going to scramble in with 4-4's and crap all the time, maybe this is best????
TO DEFEND DONT:
XX to force pard to bid 2c then you can pass or bid 2D, both to play
all systems on from there (notice how it didn't get in your way, at all?)
2d and 2d, use Lebensohl
2H, use the same defense you use against Michael's Q bids. If you haven't discussed this, I'll give you a quick and easy defense...it will come up a lot. 1. bid either of the other two suits (minors) to play. 2. Q bid a suit you have stopped with a game going hand, trying to get to 3N. 3. Bid 2N as a one round force, (not necessarily a good hand), showing either a game force in one minor, both minors, or both minors, merely competitive. Pard will pick a minor. On your next bid, pass if you just wanted to compete...bid your minor if a game forcing one suiter (regardless of whether your pard bid it, or the other minor), and Q bid again with both minors and a game force.
2S..back to Lebensohl
What I have written looks complicated. It is a little, but if you see the principles, and your partner knows anything too, you can fall back on principles. They are:
If defending against a known 1 suiter, use Lebensohl
If defending against a two suiter where the suits are known, use Q bids to show stops, new suits to play, and 2N to show the other two suits. With 2N, you can quit when partner chooses, or you can make a game force by now bidding your one suiter or make a game force with both suits by Q bidding again.
If defending against 1 known suit, 1 unknown suit, use Lebensol against the known suit, and ignore the other suit (best you can do, not perfect, but a lot better than nothing).
For you analytical types, there is one more thing to stick in these principles. If your side starts with 1N, the first objective is to get to game (3N) safely. Use the principles above. If you are in a suit bidding war, like a Michaels Q bid situation or unusual nt situation, one change needs to be made: Use the Q bids differently. You can turn their own bidding on them, use what is called "higher-to-higher, lower-to-lower". Q bid their highest suit to highlight interest in your highest suit, and Q bid their lowest suit to highlight your lowest suit (the two other suits). An example: 1c(by your partner), and they make a Michael's bid of 2c. You Q bid 2S...that's their suit, but you are saying you have a good D suit and a good hand. 1c-2c-2H...you have Q bid their lowest suit, the one pard opened, and are saying I have a good hand with clubs in support. This works for when you open 1 of a major and the opponent bids the unusual 2N bid...same principle...higher to higher, lower to lower.
I promised you a GOOD tool to use over their nt opener. In theory, a GOOD tool gets you into the bidding over 1N with: decent major one suiters, very long one suiters of any kind, decent major two suiters, or extreme two suiters. It does not tempt you to bid with moderate minor holdings of any sort. That is proper theory and also a GOOD tool is easy to explain and easy to remember (forgetting stuff is like shooting yourself in the foot).
RIPSTRA(slightly modified from the original)
2C is a double major takeout. Clubs is your longest minor. 5-4 in the majors is a risk, but you use it there at your own discretion. 5-5 is a lot safer.
2D is your longest minor, again...and still a double major takeout.
2H is natural, I suggest something like a good weak two bid or better
2S is natural, too.
X is penalty, not a balanced hand, a suit you want to jam at them and a lot of entries (how about: KQJTxx Axx x Axx?). That's my kind of double..partner will leave the double in with almost anything..and be happy to leave it in with two Queens. If he can't leave it, he pulls to 2C unless he has a 7 card suit.
2N-both minors
3 of anything is just real long. Note that you cannot bid a minor in this unless you are very, very long in it?
Why bid your longest minor even if it is maybe only 2? Your poor old partner might have a 6511 pattern with minors. You are in deep water. He can pass and play that minor at the 2 level. It just may not be in the opponent's best interest to start doubling you at the 2 level when you are 6511, you see?
RIPSTRA BALANCING SCHEME: 1N-p-p-?
Different objectives here. First, the only two suiter you want to bid is, again, majors. X with that. You need 9 points, preferably in your suits, and if only 9, preferably 55. With a little more points, 5-4 works just fine.
The problem with other two suiters is the same as in immediate seat...if you have minors involved in your two suiter, you push them out of nt, where you have a chance at them, into majors where you don't. A different problem exists when you have a one suiter.
With any one suiter and a moderate amount of points, if your pard is alert at all, he knows you have some points, and he'll lead his long suit hoping at least some of your points are in his suit. If you have a good suit, but only moderate points, he is going to give a soft trick to the declarer and maybe the contract along with it. Don't let him do that. Bid all suits, even minors, naturally here. It is always better to have a major, but even if you have a minor, your partner will never guess your minor to lead, and you aren't going to do well against 1N. Push them out of it.
Question: Why is it safe to bid on so few points? Answer: Their third seat passed. They have between 15 and 24 points (at the most). Also, your partner's points are sitting on top of their points. Your finesses are working, theirs are not. If you have 9, your pard will average 11. Once in a while, responder will have his max, 8. You can be in trouble here. However, he's going to be real leery about doubling you for penalty...you could have AKJtxxxx or something. So, the theory is: (and this works in practice), you will get in trouble a lot less than you ought to. On the other hand, if you use the re-opening X to show majors, and promising at least 9 points, anytime your pard has 13 or 14 or more, he can leave the double in, and he knows what to lead. Remember the declarer is in a world of trouble, he can't get to dummy and it wont do him any good if he could, his finesses arent working.
You can explain Ripstra quickly: 1. in immediate seat, bid your longest minor for a major suit takeout. 2. All other bids are natural, except for 2N, a minor take out. 3. Balance with natural suits or X with the majors and at least 9 points.
It's right, in theory. It's impossible to forget. There is never any confusion. What more can you ask for?
