I think, in this 1NT, 2H, 2H situation where it's obvious to everyone at the table that North was trying to accept a transfer rather than showing something about their own hand, 2S is a comparable call, under both Law 23A1 (it has the same purpos…

I think South's reasoning is correct here, and should apply regardless of South's hand. As such, if South has been consistently asking in this situation, there is no problem – and if South hasn't been consistently asking, then that would probably…

If you don't consistently ask, then both asking and not asking convey UI. (It is rare for players to call the Director on the basis that a player didn't ask a question, but theoretically they should be doing it more often – people who use the pol…

It is very common in the US for 1NT, 2C; 2D/H, 2S to show an invite with 5 spades (the sort of hand that most players would bid 1NT, 2H=S; 2S, 2NT) – it makes it possible to stop a level lower, and also handles invitational hands with 5 spades an…

I thought Stayman was announced (rather than alerted) even if it does allow responses above 2S, as long as it still has the basic purpose of asking for four-card majors. For example, I have considered (but not actually played) using the 2NT and 3…

(Note: in this post I'm focusing only on the "subset" part of comparable calls, Law 23A2 – the two other possibilities, "same meaning" and "same purpose", clearly don't apply in this case.)
The 1C opening denies certain hand types that th…

Something that's worth noting more clearly is that which pairs play which other pairs is only half of what makes a movement fair – which directions they are sitting in is also very important. It is, for example, possible to construct an all-play-…

Not sub-strength – the situation that matters is when the game might have enough HCP to be bid normally, but goes down due to, e.g., a lack of stopper. (The specific situation that prompted this is that RHO opened 2NT, and I had a good…

On the subject of 2NT announcements: a situation came up recently where I did actually need to know the 2NT range (I was considering a penalty double, and needed to work out the odds that the opponents would raise to 3NT if I didn't double, which…

I assume that "hearing range" in the regulation means hearing range via sound transmission through the air, and doesn't count sound transmission over the Internet via the playing platform itself.
(This matters because RealBridge allows yo…

Law 44C says that the obligation to follow suit takes precedence over all other requirements of the Laws, presumably including the requirement to play only cards that are in your hand. The "any card" in 44D could also be interpreted as allowing t…

Mathematically, this is only possible if someone played the same card twice (which is physically possible, if a player accidentally or even deliberately picks it up from a quitted trick). So it's probably possible to figure out who com…

Along similar lines – if the defender not on lead attempts to lead face down, is the lead automatically retracted? Or does declarer get a chance to accept it?
-
I'm not convinced that overcalling a pass is an irregularity – there's no way (or at least should be no way) for the other players to distinguish an attempted overcall from an attempted opening bid, except by the auction leading up to that point …
-
I think a) this is a psyche, and b) whether it was fielded or not should be judged by the pair's actual system, not by commonly used systems. Not every pair bids higher when raising after a double (especially weaker pairs) – it's a common treatme…

I assume this is a question about whether this agreement is legal at level 4? Assuming that the three-suiters always have both majors, this is the same sort of hole in the rules that Wilkosz fell into under the previous rules: it's illegal if int…
-
It isn't the current rule, but after reading a number of discussions online about this subject, I think the best rule would probably be "there is no UI if third hand plays to trick 1 within X seconds of the opening lead" (for some suitable value …

27B1 allows correcting calls either to a comparable call (27B1b), or to "the lowest sufficient bid that specifies the same denomination(s) as that specified by the withdrawn call" (27B1a). "Specified" in the Laws is often used to refer to which s…

I just spotted a broken reference in the latest draft: 6C3 references 5D1(a) but there is no 5D1(a) (indeed, there is no 5D1). I suspect the definition of "strong" was moved to the glossary, but the reference to it wasn't updated for the new loca…

I think this is based on how frequently the upgrades happen. My main partnership's "12 to 14" opening in first and second seat very rarely has an 11-count – but it's almost always in the range (I can remember around three total exceptions in the …
-
Something that's unclear to me with respect to the proxy rules: suppose after 1C (1H) X, the double shows 4+ spades, and 3+ (but usually 4) diamonds (i.e. a "two-suited negative double"). Is this a proxy call for spades, or is it just left unaler…

If you're trying to create a single-winner movement from a Mitchell at a table count that low, shouldn't you arrow-switch only about half the boards of the last round, rather than all of them? Otherwise too many boards get arrow-switched and the …

I think "top" in terms of a penalty is referring to the hypothetical top a pair would get on a board if they beat the score of every other player, not the actual highest number of matchpoints that anyone scored on the board. (Bear in m…

Law 68B2 attempts to apply Law 16C to information arising from a concession made by one defender that is contested by the other defender. The problem is that Law 16C is written assuming the existence of an offending and a non-offending side, and …

If you think all your cards are good, playing them in any order is a normal line (and failing to guard against the possibility that you've forgotten a trump is at worst careless – if I remember correctly, miscounting in general is considered care…

How quickly did declarer play the first card from dummy? In theory, that card's supposed to be delayed in order to give both defenders time to think about the hand, even if the declarer doesn't need the thinking time.
(I try to consistent…

Shouldn't that answer also cover the fact that not asking is also unauthorised information to partner? Knowing that your partner's choice of call is not affected by the meaning of the opponents' call can be very relevant information in s…

Hmm, in terms of non-competitive bidding, what about "the shape requirements for an opening 2NT are looser than the shape requirements for an opening 1NT" (assuming that both bids are played as natural). (Even that is something that not every bri…

Even the 3 level opening bids can lead to controversy sometimes – I was criticised by an opponent recently for opening 3C, white versus red, with only six clubs. I assumed (and continue to assume) that this doesn't need an alert, but it seems tha…

It's easier on BBO, where you can ask about calls even when it isn't your turn to call – in any "always ask" position, both you and your partner are immediately clicking on the call to ask, so it only remains unasked-about if both of y…
