    1. I do understand the theoretical argument made. For tactical reasons I’d say 4 hearts is the preferred bid. It will be possible for either party to assess on what basis they should decide their next decision. In such cases it is good practice to let the opponents make the final decision.

    2. It is the standard approach to bid 4 diamonds yes. However that approach has a huge disadvantage which at THIS vulnerability is not the biggest issue, but at all others really is bad. Partners double CAN be a strong balance hand. It would not be the first time a 5 card Q appears in dummy with 3 small in the opening hand an partner having a 19 count with AKJT. There is nothing wrong with doubling here instead of bidding 4D just have the agreement is shows at least 1 4 card major. If will provide the occasional huge penalty. Bidding 4 D on the same hand forces us into 4NT in case partner has the balanced hand which does also not always make.

    1. It is better to bid 4 hearts in order to make your intentions clear and make it more difficult for the opponents to defend both in bidding and playing. If you double, and your partner bids 3H , you will still have to make the same decision later because it would still be difficult to pass with this hand

    2.you will certainly reach game with this hand and doubling is superior because it keeps you at a lower level of bidding with more room to explore slam possibilities

    3. Interesting deduction even though risky as it might give away an extra trick in duplicate bridge. Partner may still be singleton in clubs and opponent be singleton in diamonds

    I don’t agree with dbl on the first one. While it make not be a penalty dbl, it should show some interest in defense so that partner can pass with a suitable hand.

    1. X wrong UNLESS you have agreed to play maximal double otherwise what to do with a genuine penalty X (with D values?) – PASS??) . Bidding 4H immediately also invites possible phantom save 5D from ops…espec on BBO : )

    1 double as a penalty double is possible but will be much less the case than playing it as an invite,
    Interest in defending is useless and unplayable. When should partner pass?

  30. Jules Wilkins

    In response to those who disagree with the first X: 1) if playing maximal doubles then this would be the only way to invite game. Had their suit been clubs then 3D would be invitational and double would be for penalty. I was intrigued to see X described as a general game try with no mention of it being maximal, but logically even in a pickup game where this is not discussed I would X if my partner was solid as logically there is no other way to invite, with both opp’s bidding diamonds one is far less likely to hold a hand that would want to make a penalty double, and it keeps the bidding low with slam still being possible with some hands. The notion that bidding 4 hearts is right is playing both sides of the table…you are just not strong enough to insist on game and you don’t know where partner’s values lie, with the examples given making the point very well. Finally if you double and partner bids 3 hearts there is no other decision to make as one reader suggests. Either bid 4 hearts yourself in the first place or respect partner’s decision. To double first and then overbid to 4 is a message to partner that he cannot trust you, leaving him to make decisions in the dark before finding a new partner.
    I was happy to get full marks, but still view it as a learning experience…if one works out the answer and it seems logical, trust the logic.

    On board 4, it looks like AK of hearts and then spade would achieve the same result. It loses to 3-3 H when the queen sits with the clubs, wins if the queen of hearts drops (that’s your ninth trick including the spades), and is neutral in the scenario described above (no entry back to clubs, we will still win 3S, 2H, 2C, 2D).

    This is really too hard for me
    Thanks for the explanation!

    I like the concept of double on board 1 as a help try but I am sure my partner would consider it penalty. It would take a bit to open the mind to the concept. Also the idea of using cue (opponents suit) it very useful.

    Clever returning a diamond J on trick 3. In matchpoint scoring this is a top or bottom return. Helpful if the explanation includes this.

    Jeg kan ikke finde ud af hvor jeg kan stille spørgsmål, så nu prøver jeg her, da jeg kan se du er fra Blackset. Den sidste tid har der ikke været turneringer fra BBO for singler et par timer om aftenen. Hvorfor. Det er savnet. Hilsen Solveig

    Try answering as if you are playing a pick-up game on BBO with a randomly assigned partner

    The first question has many things to do with our own style. Of course, double is right if you were planning to invite game. But is this hand inviting strength? It depends largely on your own style. I thought after the 2D bid, I could expect a black king to be in bad position, so I will simply bid 3H — I don’t think our side has enough strength for game — I choose to underbid. Also I see somebody directly bid 4H — overbid.
