Back to reality
Personal totals for the tournament:
26 sessions of bridge, including 8 midnight games
208 deals in matchpoint games
336 deals in imp scoring
32 masterpoints won (3 platinum, 22 gold, 7 red)
3 different partners (6 deals each with Josh and Shaz, the rest with Sean)
34 alcoholic drinks
5 visits to Chipotle
4 meals of Indian food
We managed 2nd place four times (in a bracketed KO and 3 midnight games) but did not win anything so did not come back with any of the maple syrup section top prizes.
A wise top-notch bridge player (jlall) has said that in matchpoints when the auction goes 2NT-P-P, you should double. When the opponents have 20hcp opposite a near yarborough, they go down much more often then they make because of having to lead from hand so often. In side games on the last day, I got a chance to try this theory out twice. Both times dummy hit with a nice 4-count and we wound up giving up an extra overtrick in desperation, scoring -1090 and -690. Maybe next time we'll get +800.
We now have at least one more person on board the Swedish Canape train. Yay.

Coming in at the 4 level in a 4 card suit
Sunday, April 17, 2011
System wins and losses
Anyway, Friday night I picked up ♠AQ8xx ♥9 ♦KQxxx ♣xx in first seat both vul. I opened a canape 1♦. Sean bid 1♥, rho bid 1♠, Sean dutifully reopened with a double. LHO made an SOS XX with his 1-4-4-4 1-count, which was left in. We dropped a trick and only beat it 1 but still felt good about +400. We just didn't think it would be a win 18. Our teammates defended 4♠X and collected 1400. System win.
In the bam at favorable vulnerability I held ♠AK9x ♥x ♦K ♣KQJxxxx and opened a canape 1♠, which was passed out. The good news was that the opponents had missed their 9 card spade fit. The bad news was that they couldn't make game and we could make 5♣. Sean's hand: ♠ ♥QTxxxx ♦xxx ♣ATxx. System loss.

Unusual Penalty Doubles
1♥ was 18-20 bal or 23+ bal or 17+ 4+♥ unbalanced and possibly canapé.
Saturday night, I made yet another penalty double and Sean had a crappy hand. This time my LHO dealt and Sean held ♠QJ4, ♥T5, ♦QT83, ♣AT53. Our auction: P-P-1♥-P; P-X-1♠-X; 2♥-P-P-X; P-P-P. Since we do not play strong NT overcalls (1NT would be takeout showing 4 spades and a 5 card minor), he is aware that I may well have a strong NT but just have no bid. Therefore, balancing on lighter values is probably a good idea, but in this case, he has a decent balancing double at the one level by a passed hand whatever your system. As it turns out, all I had was a 4-3-3-3 hand with A-AK-K and 3 small hearts and would have never doubled 2♥ if the opponents were not vulnerable in matchpoints. With trump leads at every opportunity, we prevented a diamond ruff in dummy and set it one for +200 and a top. The rest of the scores on that board were pretty evenly divided between +100 and +130.

Pre-Alert: Canape, Variable 1C Openings
We got to the table and, per ACBL procedures, pre-alerted that we play canape. I also mentioned we play a variable 1C opening and they quickly agreed to treat it as natural. I normally don't mention the 1C opening in a pair game because it's not a pre-alertable and can take up a lot of time, but in an 8 board match, I generally try to mention it to them as a courtesy. A couple of boards into the round, Sean opened 1C, alerted and explained as balanced 12-14 or unbalanced 17+ or any 18+. Jack overcalled 1H, I passed, and Claudia bid 2C. What happened with the rest of the hand is unimportant. The point is that they didn't know whether 2C was natural or a cuebid showing heart support, even after agreeing before-hand that they would treat our 1C as natural. In my opinion, and the opinion of most people, you should play "imaginary cuebids" to show a good heart raise. Opener is very likely to have a weak balanced hand, and you definitely need constructive bidding available. There are several specialized defenses to multi-purpose 1C openings, but I don't think any of them are worth playing - just assume it's a "could be short" 1C and bid naturally.
ACBL laws and most directors I have asked clearly state that canape is pre-alertable but any system with 1C as a forcing opening is not pre-alertable, whether it is precision, polish, swedish, or some similar variant. Most good players know what methods they use over a big 1C opening, over a standard 1C opening, and over a "short" 1C opening, but I have found that most do not know what they do over a variable 1C opening even though such systems are fairly common worldwide. In Poland, 1C is a typically a balanced 12-14 or 15+ with long clubs or any 18+. In Sweden, it is a balanced 11-13 or any 17+. In the Asbury-Gannon Swedish Canape system, it is a balanced 12-14 or unbalanced 17+ or balanced 18+.
The purpose of pre-alerting is to allow the opponents to discuss how they will defend against a system or convention that is highly unusual. Canape is definitely unusual and the fact that we can frequently open the bidding and conceal a 5 card side suit is unexpected (which therefore could never be alerted in the bidding), but there's not really anything the opponents could have to discuss about their bidding. Bidding is still natural (opening 4 card majors is and never will be any sort of an alert). The canape rebid of a 5 card side suit is definitely alertable, but there's still nothing the opponents should do different from standard, at least in what their bids mean. A variable 1C opening seems to need a pre-alert more than canape, at least in the US where most players are unfamiliar with such systems. Without a pre-alert, the opponents will be caught off guard and frequently do not know whether to treat 1C as "could be short", natural, or big, opening up many potential cases of mis-information, bad alerts, failures to alert, and general confusion.
I sometimes want to tell people what our 1C opening is and then tell them that they need to decide how they are going to defend against it but that is very time consuming, especially when playing only 2 or 3 board rounds. And sometimes I think that when I alert one club and explain it I should suggest some defense or tell them they can discuss what they play over it at that time even thought neither of those are technically allowed. But it would eliminate the need for a director call for misinformation or having all of us at the table just unsure about whether he had a takeout double of 1C, or the majors, or a strong hand, or just clubs. In a way, though, the lack of an agreement probably keeps many people from entering the auction and gives us a slightly unfair advantage, even though I'm sure we are following the alert procedures properly. The fact that our 1C could be a flat 12 count probably keeps out some of the ragged nuisance overcalls and preempts that people often make against a strong club because you don't want to deceive partner who may well hold a very good hand if we have the weak NT variety.

Making the Proper Inferences from Canape Bidding
The declarer north should have been able to make this 4SX contract against us, given the bidding (and the appropriate alert explanations). Granted, if south had not jumped straight to game, I would have bid hearts and then making the proper inferences would be easier.
Dealer: S Vul: EW | North ♠ AKT95 ♥ J532 ♦ 32 ♣ 85 | |
West ♠ 64 ♥ AQ974 ♦ AQJ4 ♣ QT | ![]() | East ♠ QJ ♥ K86 ♦ T9876 ♣ J74 |
South ♠ 8732 ♥ T ♦ K5 ♣ AK9632 |
West | North | East | South |
1♦ | 1♠ | X | 4♠ |
X | Pass | Pass | Pass |
When north played the ace of spades, partner dropped the Q. Obviously, playing the other high spade will lead to victory but that's definitely not right. He then played the ace of clubs, under which I played the Q. I was kind of thinking that I need him to play me for a stiff club and Jxx of spades (assuming he also knows I am 5-4 in the reds) and to next finesse into partner's now stiff J. But he continued with another high club. Now I was sure he would get it right. I am marked with 2-5-4-2 shape, and with north-south only having 18 hcp, it's nor unreasonable that I doubled on high cards rather than a possible spade trick. But he continued playing me for Jxx of spades by ruffing a club (as I parted with a diamond), then ruffing a heart to lead another heart, attempting some sort of coup since he could not set up clubs and get to them or trump all the hearts and pick up trumps if I had 3 trumps. That would have worked if I started with something like 3-4-4-2 or 3-3-5-2, neither of which are possible distributions for a 1D opener in our canape system. Maybe he didn't ask about the alerts on his side of the screen.
Note that standard bidders don't really have any chance to defeat 4S as I would open 1H and get a heart lead, so this can kind of count as a win for canape. We would never get a diamond led through the K and declarer would surely disobey the rule of restricted choice just to avoid letting east in to lead a diamond.

Montreal Relay - Not Something I'll Be Promoting Any Time Soon
After a standard 1C opening (or a could be as short as 2 but natural):
1D is normal response values but artificial promising no 5 card major and at least one 4 card major. Thus, opener must bid a 4 card major if he has one next and minor suit lengths are still ambiguous.
1M response promises 5 and 1NT denies a 4+ card major.
Yes, it is true that this system will get opener playing your 4-4 fits and you will find 5-3 fits sooner. That is what people seem to think is the advantage of this little convention. However, it really slows down the process of finding the 4-4 fits, especially when they bid over 1D. Now you are kind of clueless as to whether this is a total misfit hand or youhave a fit and need to be competing. Are 5-3 fits really that hard to find after a normal 1C-1M start? With so many ways to check back for 3 card support and support doubles, responder promising a 5 card major at the 1 level seems very unnecessary. Getting the opener to play the hand may be a very slight advantage when you wind up in a partscore, but by the same token, you get responder playing 1NT when you don't have a fit. And when responder has a stronger hand, who gets to declare is pretty irrelevant, so that little plus is a wash.
A couple of rounds into it, I picked up AKTx, AJT, Jx, AQxx and dutifully opened 1C and she bid 1D (alert). I would hate to bid 1S and then have her play NT even though she specifically said that a NT rebid by opener would deny a 4 card major. So I bid 2NT anyway and, yes, we missed a spade fit. 2NT is rarely passed. Why not checkback for a 4 card major, even bid 3S if you're not sure 3 of a minor would be forcing?
This is like the anti-Walsh convention, and I like Walsh. Walsh is little more than bypassing any number of diamonds to bid a 4 card major in response to 1C. That way opener can then bypass a 4 card major after 1C-1D because responder either has no 4 card major or has enough points to bid it now, over 1NT. You get the bigger hand playing 1NT more often, which is probably more useful than getting the big hand playing 2M. And you find out about possible fits sooner so that interference doesn't cause such a problem.
Obviously I'm going to like Walsh better because I like canape and Walsh is kind of canape-ish. True canape would bid a 4 card major before a 5 card diamond suit regardless of suit strength (not only with minimum responses as in Walsh), and true canape would bid a 4 card a diamond suit before a 5 card major in response to 1C, which isn't such a bad idea if your partner is in on it too.
If you haven't figured it out yet, I'm all for finding out the 4-4 major suit fits as soon as possible so any system or convention that delays bidding 4 card majors isn't going to rank very high on my list.

Polishish Canape Issues: Determining if Opener has a weak NT or a Strong Hand
If lho of the 1C opener interferes, that's actually a little easier to deal with. Responder just bids as if partner opened a standard "could be as short as 2" 1C. Negative doubles are all on, negative free bids are on (for majors only), but 2C and 2D are both natural 1 round forces. Opener rarely has the big hand when lho and partner both bid, but there are still plenty of ways he can show a big hand - jumping and cuebidding, normally all below game and in a game-forcing situation.
If lho preempts, we even more bid as if we opened a weak NT. Lebensohl applies and opener bids over a signoff only if 17+ and obviously doesn't accept the relay to 3C is he has a big hand. But natural bidding takes over and we have yet to have any real problems that are worse than standard. I must say, in probably 25 sessions of playing this face to face, lebensohl after a 1C opening never came up.
Polish club is substantially superior to a strong club, in my opinion, because opponents don't so much go out of their way to make nuisance bids because they have to bid more constructively because it is still reasonably likely to be their hand. I probably should learn the Polish standard system WJ05, something I might be able to play with someone without weeks of discussion and practice.

Canape System Win

Balancing Doubles in Canape
Another thing I’ve been thinking about is what does a balancing double in a canapé system show. Like 1D-(2C)-P-P-X? In standard, you would tend to have almost any non-freak hand without length in clubs. Maybe 3-4-4-2 or 4-4-4-1 or 4-3-5-1 shape, possibly even 3-3-5-2, and it could be an absolute minimum. In canapé, when 1D guarantees having not exactly 4 in either major, but guarantees an unbalanced hand, double as takeout doesn’t make a whole lot of sense. None of the 4 hand shapes I mentioned above are possible after a canapé opening. I mean, 4-3-5-1 is a possible shape but with 4 in the suit already bid, so 5-3-4-1 in this auction would be a possible holding. Do we really want to suggest that partner bid either major when we are 5-3?
But using insinuating doubles (basically negative doubles that only guarantee 3 in unbid majors) and negative free bids (1D-(2C)-2M = constructive w 5+), the need for opener to show any sort of major suit length when it is passes back to him isn’t so important. Perhaps it should be a penalty double but that doesn’t make sense because on the hands where you will want to defend 2CX, partner will have made an insinuating double. Maybe it should imply canapé with 5 in the suit below the overcaller’s suit plus tolerance (2 or 3) in the other suit. So, after 1D-(2C)-P-P, X can be 5-2-4-2 or 5-3-4-1 or 5-2-5-1. And After 1S-(2D)-P-P, X = 5 clubs (4-3-1-5 or 4-2-2-5). I think I’m gonna go with the latter for now. I think.

Polish Club Canape
There are 2 downsides that I see. Opening NT is 15-17. Okay, not really a downside. It's just totally normal while nothing else in this system (when we get to open the bidding) is normal. and the auction 1C-1D-2D is too difficult to handle. In this case, opener is 17-21 with long diamonds or (4 diamonds and a longer side suit), a lot like our 1D opening which is 11-16 with long diamonds or (4 diamonds and a longer suit). Responder could have up to 11 if balanced, 7 if unbalanced, and may be fearful of bidding on without significant values. We may find ourselves in an inferior diamond fit when everyone else has no problem getting to the 5-3 or 5-4 major suit fit.
Our 1D through 2C opening bids are basically the same as before, but now the max is 16 hcp instead of 15 - they all are one-suited in the suit bid or 4 in the suit bid with a longer side suit. 2D is still mini-roman, now 13-16 instead of 12-15. 2M openings are 8-12 with a 6 card suit. 1NT is 15-17 instead of 12-15. the big change is that 1C is now either 12-14 balanced OR 18+ balanced OR 17+ unbalanced instead of any 16+.
There are a couple of big upsides in that it's fun and the opponents may not know how to react. I suppose most will or should treat it like a natural 1C, but I don't really know. I don't recall every actually playing against anyone playing a Polish club system.

Teaching a Computer to Bid part 1
If there's one thing I've learned from working as a software engineer and redesigning an old and incredibly unorganized piece of software for the last few years is that knowing your requirements and having a detailed plan are essential to writing good code. Yet I jumped right in and started coding because I wanted to see some results right away.
I have also realized something about my programming interests. I dislike programming GUI's. I guess I actually knew this before. I never liked doing any kind of interface programming but I enjoy the algorithms and logic parts of software. So, this project is gonna be all text on the console unless someone else volunteers to write a GUI. I don't even want to think about programming a computer to actually play bridge - that has to be way harder than bidding.

2♣ Opening in Canapé Systems
There are some things I dislike about Rexford's system, mainly the fact that the 1♦ opening could be on a void. In my canapé system, the 1♦, 1♥, 1♠, and now 2♣ openings are the same: either one-suited in that suit or 4 in that suit with a longer side suit. hands with 5M and 4♣ are awkard to bid after opening 1M because of the difficulty of accurately showing the second suit (having to treat it like a one-suiter or a balanced hand), so I finally gave in to testing the effectiveness of 2♣ being a possible canapé hand instead of just single-suited with clubs, and the problems seemed to be relatively few.
The structure Sean and I came up with yesterday for how to bid over 2♣ as 11-16 hcp with either a canapé hand with a 5+ card major or single-suited with clubs is as follows:
2♦: artificial 1 rd force, may be any strength; if game-forcing, no 5 card major
2M: 5 card suit
raise: invitational
cheapest bid in other major: mixed raise
2N: max w/ long clubs
3♣: min w/ long clubs
2M: 5 card suit, constructive but not forcing, usually tolerance to play 3♣ opposite a one-suiter
2NT: artificial game force w/ a 5 card major
3♣: no 3 card major
3♦: at least 1 3 card major
3M: 5 card suit
The other option for dealing with the 5M and 4♣ hands in canape is to use 2M openings to show these hands, which really is easier to handle, but the value of a 2M preempt is too good to use for something else. Now, if we could use 2♦ as a weak 2 in either major, then I wouldn't be opposed to this treatment, but then this wouldn't be a general convention chart system.
Edited Sept 1, 2010:
The rest of our opening bids are now:
1♣: balanced 12-14, any 17+ unbal, any 18+ bal.
1♦/♥/♠ :11-16, 4+ card suit, could have longer side suit (1M could be 4441 w/ shortness in other major)
1NT: 15-17
2♦: 11-16, 4-4-1-4 or 4-4-4-1
2♥/♠: good weak 2 (9 to 12) in 1st and 2nd seat. 3rd seat much less disciplined
2NT: 5 to 10, 5-5 minors
Please see my other atricles on canape bidding.
This Weekend's Bridge Results
Final tally: +55 imps in 172 hands: 44 hands with Sean, 13 w/ Val, 30 w/ Carol, 8 w/ Harlan, 19 w/ Ramesh, 17 w/ Gideon, 12 money hands with robots, 21 w/ Bob, and 28 w/ Emory. And this time the best results were with Emory (+69 imps in 28 deals), as should be the case. In addition, much time was spent at the partnerhsip bidding table testing out new methods for our canapé system and sort of teaching it to others.

Anderson sectional
left at 7:30 to play in the Anderson, SC sectional on 4 hours of
sleep. Round one of the KO goes okay and we were fortunate to draw
owen/Warren again in the 2nd round (we played them in a 3 way the 1st
session). Disastrous.
A few more beers later, ramesh and i put together a nice 61.46% game.
It was the biggest jump i've seen in the last round - from about 56 to
over 61%, and our last round was only 16 out of 24 matchpoints.
Sunday, the good bridge continued as Ramesh (godot79) and I and Jim
Gentry and his partner came from behind to win the Swiss. Our system
worked well for us this day and slipping defenseive tricks was kept to
a minimum. One thing I like about our system is that it sort of makes
us, my partners especially, be disciplined. Our 1NT is 13-15 so
basically you have to pass all flat 11 and 12 points hands. And due to
the canape style, it at least seems harder to cheat a little on your
point count or distribution.
My favorite hand was when we got to double the opponents in 1S. I
opened a big club with AQT8x, Ax, Qxx, AJx. LHO stuck in a 1S bid and
partner doubled, showing any 5-7 hcp. All pass and she scraped up 4
tricks for 500 to us. At the other table, my hand played 4SX, also
down 3 for 500.

Reasons I Like Canape-style Openings
I began creating this bidding system a couple of years ago with Ramesh, taking bits and pieces from other canap? systems that have system notes on the internet. Some things are still a bit fuzzy like how to bid 5-5 hands and how responder can use canap?. I wanted a system that would be good for matchpoints since that is my favorite type of scoring (well, BAM actually is my favorite but those games have gone out of style for the most part).
Anyway, back to what I like about this system. It is largely a natural system. Opening 1D/H/S promises a 4 card suit at least. Bidding a different suit at your next bid show 5 in the 2nd suit and exactly 4 in the first suit. This has kind of a preemptive effect as you more frequently shut the opponents out by bidding his 5 card suit. I love the auctions that go 1H-1S-2D-P and the opponents have an 8 card heart fit. While at standard bidding tables, it may go 1D-(1H)-X-(2H)-all pass or something similar. Responder rarely has to take a preference back to the first suit because the second suit is guaranteed to be longer than the first. So opener can ?reverse? with any hand safely. With 5 hearts and 4 diamonds, we open 1D, then over the expected 1S response, we can bid 2H even with a minimum and not miss out on a 5-3 heart fit. We learn about 4-4 major fits sooner than in standard bidding and the 5-3?s are still easy to find because we are not afraid to reverse into a 5 card suit at the 2 level. There isn?t much use for 2/1 game-forcing since opener is limited to 11-15 hcp. Responder will have a much better idea of slam prospects that opposite a regular opening with a 12-21 point range.
The weak notrump is also something I like a lot, even though 12-15 is a bit of a large range. But, again, it is effective at shutting the opponents out of the auction. I tried for a while to use an 11-13 NT range and use the 1D opening for the 14-15 or 14-16 range, but we found ourselves opening 1D much more than anything else and ideally, you would like all the opening bids to be used about the same amount.
Our big club structure is effective and mostly natural. 1D response is 0-7hcp. 1H through 2D responses are transfers, showing a game forcing values with 5 cards in the next suit. Opener only accepts the transfer with support. 1S over 1C shows any balanced hand with game forcing values. That way opener can bid 1NT and then responder can use puppet stayman. After 1C-1D, 1H is any 20+ hcp and responder rebids 1S with a real bust hand (no A or K or 2 queens). If they overcall, we play stolen bid through 1S, otherwise double is 5-7, pass is 0-4 hcp or a trap pass.

Canape Bidding System
We played an interesting bidding system - strong club with canape style openings. I basically picked out various parts of other systems and then tried to work out the kinks to have everything decently covered. Here is the system summary:
1C - 17+ hcp balanced, 16+ unbalanced, with transfer responses (no further relays)
1D - 14-16 balanced OR 11-15 unbalanced w/ 4+ diamonds and possibly a 5 (but not 4) card major
1H/S - 11-15 hcp, 4+ card suit. if only 4, has another 5+ card suit
1NT - 11-13 hcp
2C - 11-15, 6+ clubs, no 4 card major
2D - any 4441 or 5440 w/ 5 of a minor
2H/S - weak2
2NT - 5-10 hcp, 5-5 minors
Negative doubles after 1M-2m show 3 card in OM, negative doubles after 1m-1M show 4, negative doubles after both majors have been bid show 3 card support in opener's major.
I've decided that the 1D opening occurs too frequently. At least it felt like it happened too much. So, I think next time I play this system, I'll change the NT range to 12-15 or 13-15. 1D becomes a totally natural bid (although it could still be a 4 card suit with a 5 or 6 card major).
The hands where canape style openings don't work so well is with 4 clubs and a 5 card major. We decided we had to treat it like a major one suiter or a balanced hand, but some other systems use 2H/2S to show that hand. I think weak 2's are too important. Another option is to use 2C as either 6+ clubs or 4 clubs with a 5 card major. That one may be midchart, though, and I don't want a system I can only play in flight A events.
