I just committed to playing with Jack. Teammates will be Ken/Pat.
That's all I know. :)
I do not even know team name.

Jack can be in charge of names. The Wackos?

It would be good if the four of us could have a game sometime. Perhaps we could use zoom and chat between hands? We could play a team game with four robots at the other table and that way we could chat much or as little as we please.

I hadn't seen this. I pass with such hands. Usually it works out.

My thinking, I suppose I am a traditionalist.

On this hand partner has three card support, the AK of hearts, an outside K, and a stiff diamond. Still, good defense holds me to 8 tricks. Am I really so keen on declaring this hand in a spade contract? If I am non-vul against vul, ok. But vul? I'd rather not.

More generally: I think that 2S should suggest that I'll probably be ok in 2S if partner has only modest values and a doubleton spade, and I will probably be ok if partner has three spades and some shape and so competes to 3S. And, if my Lho declares, I would like to think I will be fine with an opening spade lead from partner. My posted hand satisfies this last requirement.

Another way of thinking about it. Some expert, I forget who it was, said that you want to give partner accurate information during the auction but then, if the opponents buy the hand, you might well regret putting this info out there. Meaning here that when the opponents play a diamond contract then knowing spades split 6-3 might be of use to declarer.


I don't usually play multi bids, but I will comment on N's response to the 2D call at the other table. At least as I play multis, when I play them, it seems N's bid is 2S or 3S. Yes his hearts are (much) stronger but the 2S bid says so. The idea is to say "Yeah, I have good hearts in case that is actually your suit, but if, as I am guessing, your suit is spades then 2S will be fine. Or he could bid 3S with the same meaning: Sure, 4H will be fine if hearts are your suit, but if it's spades then let's play 3S.

But multis need discussion and it's a matter of choice.

As to the in-between hands, too much fo 2S and too little for 1S, I don't think I ever do that if I have a good spade suit. If I have a six-card spade suit, no singleton, so 6-3-2-2 in some order, and a ten-count consisting of two kings and two queens all in different suits, I probably pass. I wouldn't call it too strong for a weak 2, just wrong for a weak 2. And I am not suicidal so 1S is not my call either. With a ten count that consists of the KQJ of spades and a couple of outside queens but not much shape, I am fine with 2S. With a six-card suit including of the KQJ and an outside A, I am fine with 1S.
Mostly, if I pass holding six spades and a ten count, it's probably with a hand where I am not at all sure I want to play in spades and not at all sure I want partner to lead a spade if we end up on defense.

4S is optimistic, I probably just make an immediate raise to 3S.

As to opening 2S on a 10 count I have been known to do it. I have never liked the idea that a hand with a six-card major could be too strong for a 2M bid and too weak for a 1M bid so I do one or the other unless there are other aspects of the hand that I worry about. Bad suit quality could convince me to pass rather than bid either 1 or 2.

Other opinions?

Glad to see you back, Jack. I hadn't realized your trip to Greece was still going on. I was wondering if you were ok, but having the cops put out a missing persons report for Wackojack didn't seem practical.

The situation you describe is a very common feature of online bridge. Here is how it went from my point of view:

I saw that you were going to Greece and would be out of contact so I thought ok, I will take a look at Jack's profile and make up a cc to fit. I had the idea you would be back from Greece in plenty of time to discuss refinements but I was wrong, so I figured ok we will go with it as is. I was aware that some, not all, multi-Landy players, use it in a modified way over a weak NT but that's one of the things I figured we would work out. It requires that we decide what a weak NT is. 14-16 is strong, 12-14 is weak, but 13-15? When I have played conventions that vary with the strength of the NT I have sometimes played that we treat 13-15 as still being strong, sometimes I have played it as being weak.Whichever pard likes.

Another problem for online conventions is that there really isn't enough room on the cc to easily list all of the options. My description spilled over to where we would put the weak not option. Playing against a strong NT the X shows a hand that has a four card major and a five card minor, or just a five card major, or just a six card minor, or a hand with 19+ points Hard to fit all of that into the space provided.

So I figured we could make up two ccs, one for when the opps play a strong NT, one for when they play a weak NT. Of course to make that work we have to know in advance whether they play a strong or weak NT. I know acol uses a week not, at least in theory, but from what I have seen of the challenges some play a strong NT, some play a weak NT.

And that's just for the Landy.

I also put RBergen on the card. I usualy avoid Bergen unless there is time to talk of when it is on, when it is off. For example, if I open 1H, and LHO doubles, is RBergen still on ? When not playing RBergen 1M-(X)-2NT is usually played as invitational. If now 3C is invitationaL then the 2NT is presumably natural. Similarly, 1M-X-3M is generally preemptive w/o Bergen so what's happening with Bergen? I have a book, by Bergen, around here somewhere that gets into all of this. I'll look it up.

Added: I see a quick discussion of what to do over 1M- X at https://www.bridgebum.com/bromad.php


As mentioned, I have generally coped with these issues by just relaxing and taking online bridge as a casual game. The idea of these challenges seems to be to make it less casual. I am up for that but it will take some work.
As to what the opponents could make of my brief description of X as a really to 2C (you have a typo, saying 3C), it's true that "relay to 2C" doesn't tell the whole story so I was glad I put the cc up with the more complete description. At a f2f game it would be easy. I would double, they would ask, you would explain. At least in my case, I can talk a lot more rapidly and a lot more accurately than I can type.

Putting an agreement in place might well be a good way to spend some time. Maybe we could find a zoom time?

I hope you enjoyed Greece. I traveled around there a bit.  I had read Oedipus Rex in college soI went to Delphi where  Oedipus had learned that he would be killing his father and marrying his mother. For someone who grew up in Minnesota, where we thought of history as beginning around 1850 or so, it was good to see places with an ancient reference.

Yes, LOTT is correct but not quite as you say. There is a 9 card fit in both D and S so LOTT says 18 total tricks. and so there are, the spade contract can be held to 8 tricks, and there are 10 tricks in diamonds. So LOTT is right, but it illustrates issues with LOTT. 130 to EW is the par contract, but if I (I was S) open 2S and the opponents compete then surely pard will raise to 3S, and double dummy I am off 1 for -200. But of course they won't double, and they might not hold me to 8 tricks if they do. In reality, the other table got to 4S and were off 3. And, at one point during the play of 3D, it could have been held to 9 tricks. Further, I didn't open 2S, it seemed a bit pushy when vul wit KQxxxx and nothing else. The problem with opening it 2S is not that I am worried, or not terribly worried, that I will be playing 2S off a few but rather I worry that partner will expect, or at least hope for, more with my vul opening and compete at too high a level, as happened at the other table.

So, first round,  I just passed, after which Lho opened 1D, partner overcalled 1H, Rho bid 2D, I bid 2H and then 3D ended the auction.

I asked in my post if the LOTT total could be discovered during the auction, and I guess the answer is maybe yes, maybe no. As we bid it, we knew we had an 8 card heart fit but we never learned of the 9 card spade fit. W knew of their 9 card diamond fit but I  doubt E could be sure of it.

So double dummy LOTT is right, there are 8+10=18 total tricks in S and D, or at least there are 18 total tricks if everyone declares and defends optimally.  We arrived at the par contract of 3D played EW but there is a certain amount of stumbling into it since we have a 9 card spade fit we never explored.

Bridge is an interesting game.

I can probably play, but it's too far out to commit.

It's a double birthday weekend for us--so we might be in the middle of cake and ice cream and family on Sunday. I'll try to find out.

Old joke: Four guys are playing bridge, there is a phone call for one of them, he gets the message and says "Sorry but it seems like my house is on fire. As soon as we finish this rubber I will have to go." Anyway, happy birthday to whomever and to the other whomever.

Whatever happens at the August challenge, this could be an opportunity for me to work through some agreements, either with Jack or with someone. I have few agreements.

A couple of examples from the July game:

About a week before the game Jack and I agreed to play and then you and Joe joined in. Jack was off to Greece and out of touch. I looked to see if jack and I had ever filled out a card and I could not find one, so I decided I would look at his profile and fill out a card to match and we could talk if we had time. We didn't. His profile said multiLandy (against an opening 1NT). Fine, I went to The Bridge Bum to see how they played it and they give now way but they note that dome pairs vary the details depending on whether it's a strong NT or a weak NT. Sure, but then we have to discuss where to draw the line on strong NT versus weak NT, I decided we would just go with what BridgeBun says w/o regard for the strength of the NT. Sure enough, on the first hand partner deals and my Rho opens 1NT. I held:
S: 6
H: 7
D: A98
C: AK987652

Ok, it's imps, nobody vul, there is a lot to be said for bidding 5C but I decided to trot out the multilandy X.

Pass   1NT   X   4S
Pass   Pass  5C Pass
Pass     X    Pass  Pass
Pass

Making

I had briefly alerted the X as a relay to clubs, and the opponents said that I should have done more. Fair enough, but fortunately I had filled out the convention card and noted that the X could be any of four choices:
4M+5m
5M
6m
19+
This was accepted as adequate. With more time I could prepare a sheet of explanations that I could copy and paste, but I have not done that with anyone. And Jack and I had not discussed this at all. I suppose in principle when I bid 5C it could be on long clubs and a four card major but it seems reasonable that almost whatever we are laying I have long clubs. 5C X came in.

A second example came on boars 3. This time I delay and we are whit against red. Still imps.

S: 6
H: QT63
D: AJ74
C: AK75

The uncontested auction goes
1D    1S
2C    3D
Pass

I explained, after the auction was over, that I assumed the 3D was invitational (although since I passed I guess that was clear) but I wasn't positive. And yes, I would like a fifth diamond for that 2C call but I was not going to bid 1NT on that stiff spade spot.  3D making 4 was fine since the other table was in 3NT going down.

One more example of needed discussion, although it did not come up in the match. Jack's profile says RBeren so I included that on our card. W/o discussion it's risky since not everyone agrees as to when it is on and when it is off. For example, if I open 1S and Lho doubles, then often 2NT is played as invit with four card support. Well, Either 2NT or 3C can be invit with four card support, but presumably not both. So discussion is needed.


I am thinking these challenges could lead to discussions. As I mentioned, my approach to online games has been KISS and relax. But if we are to be expected to fully explain our agreements in these challenges then that might force us to actually have some agreements. That could be good.

A couple of (belated) thoughts about A:
There is an old slogan "3NT ends all auctions". Like most slogans, this one has exceptions. Partner surely has spade length and perhaps planned to pass a re-opening double, but exactly what else he has isn't clear. One possibility is that he has substantial support in clubs. With good clubs and the spade A, a reasonable course of action is to first bid the 3S and then, when pard (me) bids 3NT, pull the 3NT to 4C. That would get us to 6C since I could reasonably expect that after drawing trump I still have a trump in the dummy so I do that, then run diamonds pitching heart losers on diamonds. It's still might not be a cold slam, it would be really nice if pard had the heart Q, but it's a reasonable shot.
As to the possibility that pard actually wants to play 4S: Well, he can bid 4S over 3NT. If that is what he is thinking of, at least I can say that in no way whatsoever encouraged that call. Kit Woolsey says possible 4S is the right contract and maybe so, but if 4S is the right contract opposite my void I expect pard can figure that out for himself.

Right. I didn't think you two had a misunderstanding. Or that the opponents did. The acbl disallows it? Maybe just at the lower levels? They have all these rules.
I was only speaking of my own approach/experience with online bridge. I find it to be a good deal more casual than even the club games pre-covid. I just decided I was ok with that. But if we go with the Curls approach we might well get into a less casual game. Apparently you and your opponents did so, they had this multi, you had prepared for it. That's way more than I am used to doing for online bridge. With these acol challenges I try to check the NT range and what length is promised by a 1M opening and let it go at that. I have never yet known who I am playing against, let alone what their cc says, until we all sit down to play.

We will see how this goes, it could be interesting. I think I am available in August. Maybe Jack, Todd and you are as well?

Ken
The above note was not meant to you, or any player in particular, it was just general warning, because we did not have a single registration before June 27. And I only could inform Poco1 of how many teams we had on Sat, July 2nd, less then a day when games run.
That's not fair to anyone.

So, and this is for all, none in particular, from now on, please count that Challenge runs on the FIRST SUNDAY of each month.
If your private obligations allow and you can & want to play, please form the team and register it before deadline, which will be WEDNESDAY of week prior to challenge.
And then the event will run with as many or as few teams IAC could produce.

This could lead to an interesting discussion and perhaps a change in my approach to online bridge.
Once upon a time, long, long ago, I played bridge in clubs and at in-person tournaments. I played with people I knew for years. At the club I mostly played against people I had known for years. We had fairly detailed d agreements. After the game we would often go to a bar and discuss the hands for an hour or so.

Not now.

I posted a hand today on the Sleight of Hand forum. There is a previous hand there that I posted on May 7, it got one response. OK, the MSC hands get discussed but those hands are on the outer edge. We don't discuss ordinary hands.

The result is that I have taken a very different view about online bridge. I play with a guy named Carl in ACBL games. Carl's preference is to just keep it simple and so we do. The ACBL game we play in has 12 minute rounds, 2 boards to a round, I type slowly, so forget about any details in explanations. I rarely know the opponents at all. Maybe they have a cc, maybe I understand it, that's maybe.

So I relax. I take a practical view of what probably means what and I play the hands.

If all the teams are known by Wednesday then presumably who will play against whom could be announced on Thursday. We could all post convention cards on Thursday. It could be like the old days (without the beer that came afterward).


I'll illustrate by posting here the same hand I posted on Sleight of Hand





https://www.bridgebase.com/tools/handviewer.html?lin=st||pn|S,W,N,E|md|4SKQ8763H973DT82C2,SA95H4DK654CAQJ54,ST42HAKJT6D7CKT73,SJHQ852DAQJ93C986|sv|b|rh||ah|Board%2010|mb
 

Our auction was natural. East dealt and it went
Pass  Pass  1C  1H
2D     2H    3D  Pass
Pass  pass

At the other table it began Pass 2D. The 2D showed a hand that had one long major. Then W came in with 2H, a take-out bid.

Now: I have never played this artificial 2D call, but more to the point I have never discussed with anyone I play with how we defend against it. Why would I, unless I saw their cc in advance?

This worked out just fine for us, we were NS. At our table 3D made 4. At the other table after Pass - 2D -2H they ended in 4S off 3. But this was more from not having agreements, and so taking it cool, than it was from having agreements.


Anyway, I have approached online bridge in a casual manner. Keep it simple and stay cool. If we get the matches set up by Thursday I might try a more serious approach.

We had some good luck on the challenge yesterday. I'll post the last hand. I am curious as to what everyone thinks should happen. For example, what is the par contract? Is it plausible to reach it? NS have 17 cards in the majors, and so EW have 17 cards in the minors. Is LOTT accurate and can it be confidently applied during the bidding?


https://www.bridgebase.com/tools/handviewer.html?lin=st||pn|S,W,N,E|md|4SKQ8763H973DT82C2,SA95H4DK654CAQJ54,ST42HAKJT6D7CKT73,SJHQ852DAQJ93C986|sv|b|rh||ah|Board%2010|mb
 

I am assuming that a discussion of these boards is welcome. There were more than the usual number of shapely hands yesterday, and that always leads to some guesswork.

Basically I think the reason for the club lead is this:
Again we give up on preventing one heart ruff, we try to prevent two ruffs, and we attack the transportation. Obviously overtaking the diamond J is out as a way back to hand and he needs to ruff with the small Ds, so he needs to get back to his hand with something other than trump. Assume again that declarer's clubs are KJ. On a club lead he wins in hand, cashes the heart A, ruffs a heart, cashes the D K, comes to hand with the club K, ruffs another heart, and then? No way off the board. He probably hopes for three clubs on his left and tries to ruff back to hand. Nope. More after my coffee. 

OK, I am back. One thing I hope they address: How likely is it that declarer has only two hearts? Dummy has one, I have three. Of course the remaining seven hearts could be 5-2 but my guess is that declarer has three. Or four. I suppose I could do the math but I am not going to. I just think declarer is likely to have three and so he wants to ruff twice if he can. Another thing to consider is that declarer will not be playing this double dummy, at least not if I hold my cards right. That means that if he is holding five diamonds and has transportation issues, he might well think that his best bet is to assume diamonds are 3-2 and decide that he can ruff twice in the dummy and then lead the diamond K and overtake to cash his AQJ.

At any rate, leading a club at T1 gives him something to think about. He will probably figure that the T is likely to be a short suit lead, as it is. If he has to ruff twice in dummy, he needs to get back to his hand after each of those ruffs. A club lead makes that tough unless he has a stiff spade. Of course he might. If he is 1=4=5=3 and his clubs are KJx it can go like this: Win the club lead in hand, heart A, ruff a heart,  club back to hand, ruff a heart, diamond K, spade A, ruff a spade, draw trump, small club to board, toss least hear on the good club. I do think this line requires a declarer, if he has three clubs, to have both the K and the J.  On a spade lead I think he survives with just Kxx in clubs. That is, with x / Axx / AQJxx / Kxx I think he makes on a spade lead, goes down non a club lead. I am not certain of that, but I think so. Maybe I think more later, maybe I check with Gib. Or I just wait for my Bridge World to arrive.
