North deal and open 1♣ 5 cards Major biter minor
you are east non vulnerable they are vulnerable
do you bid?
if yes what do you bid?

[DavidKok]

I'd bid 1♦ at IMPs, and probably also at matchpoints though I could easily be convinced that this is a bad idea at that form of scoring. A 1♠ overcall is also interesting at MPs. Pass and double are poor choices.

Funny how differently players see a hand, particularly as I usually agree with your logic. I see this one as a choice between X and Pass, with 1♦ and 1♠ coming in a distant 3rd and 4th place.

And I see it differently again, the less exclusive an overcall is, the more we need for it, this is nowhere near 1♦ particularly with a poor suit, P/X/1♠ all in the frame.

[DavidKok]

I think at IMPs 1♦ stands out, 1♠ is acceptable and pass is subpar but tolerable. Double is nowhere close.

[AL78]

If I were to bid I would double (I have shortage in opener's suit and support/tolerance for the other three) although it a tad light in strength. I don't see the value in overcalling on a ten high suit that, if anything, increases bidding space for the opposition.

[mycroft]

Wow. For me if I don't pass, this is an auto-double. I am happy wherever we play. With a 5cM, I bid it and then double next round, but minors are different. And ten-fifth is "a suit", I guess.

Okay, for me, it's an auto-1NT. But still, takeout.

1♦ is going to get a diamond lead from KJx into 1NT or Qxx into 3NT, isn't it? And are we really winning the competitive auction in diamonds?

1♠ at least gets the lead-director in. I'd prefer a slightly stronger suit for the 4-card overcall, but that's my agreements.

I am well known for being an idiosyncratic (read: wrong) bidder. But I'd really like to know why 1♦ is "standout", and why IMPs matter.

[pescetom]

At MP, 1S is tempting, otherwise double, although both are likely to antagonize weak opponents or a poor TD. I don't like pass and 1D does not cross my mind.

[sfi]

I'm never going to get a better chance to say something about my hand, and the most useful thing I can say is that I have support for the other three suits.

Why wouldn't I make a takeout double? It's our best chance to find the right game and allows partner to compete on hands where they may find it difficult to get into the auction. With most partners it's not even light with this shape - we have some aces and excellent spot cards. Any other call looks like a distant second choice.

[mw64ahw]

Takeout X or NT for me

[Tramticket]

As 10 HCP-hands go, this is pretty strong. I would like to have a fourth heart for a (sub-)minimum takeout double, but it feels like the best call, particularly as it will never force partner to the two-level.

As for the other choices, pass is the only one that I would consider. 1D over-emphasises the diamonds and 1S is a complete mis-description of the shape.

Also, there is a significant problem with overcalling on a four-card suit on this hand. When you eventually win the contract in a Moysian-fit spade contract, you will be forced in clubs!

[paulg]

I'm very comfortable with doubling here. It is minimum, but I'm in and out of the auction quickly.

As you are one of the better posters here Paul, I have to ask if you would feel just as comfortable with a random non-expert pick-up partner? or if the comfort comes from knowing your partner will not hang you by doing something stupid?

[TylerE]

X beyond clear. If I was going to overcall a suit, it would be ♠, not ♦.

Why overcall a crappy suit that will get partner to botch the opening lead?

[mcphee]

This hand represents a t/o dble to me and I consider a 1!D o/c a foolish thought at any form of scoring.

I think an overcall of 1 spade is right but with my home made biding would bid 1 diamond to show 4 spade and 8 hcp or more

adding west hand
West should bid 3or 4 spade

An easy X…oh damn, that H6 is actually the D6…too bad🤣
Over a 1S overcall, W is pretty weak and flat. I guess it depends if S takes action, but I’m not sure 4S is the kind of call you (or partner) will like. Green vs red is the only position I’d consider it.

The right call depends on what hands your 1♦ overcall can contain. ♠Qxxx ♥Qxx ♦Qxx ♣Qxx matches the description of your call - you really do not want to be bidding 4♠ (or frankly even 3♠) over that.

[Douglas43]

This looks like a routine double at this score. 1♦ is a bad suit and takes up no bidding space. 1 ♠ shuts out hearts which is good news if they have hearts, bad news if we do. But if we have the spades, double will still get us there.

1 DIAMOND dont steal the biding space of opponent but say i have 4+♠ 8+ point and no interest in Heart 0-3 ♥
partner should bid 3♠ with 4 spade any shape even a flat 0 point with 4+♠ 12+point can make a limit raise with 2NT
