They're vulnerable, you're not, you hold:

JT876
KQ6
542
K4

If it goes:

Pa Pa 1 ???

And:
1 Pa 1 ???

Do you overcall 1? It's a teams tourney. Great opponents.

Easy 1.

Not that I believe in the dogma, but should partner choose to lead K from Kx in spades (Edit: vs NT of course), I'd welcome it. The 8 is a great card, without it 1 would be more dubious. Being an overbidder, I'd still do it though.

Edit: Hadn't seen second sequence. Even more obvious, as partner is less limited, and I am on lead vs heart-contracts.

1. This was a problem in 1982.

It isn't now.

I feel less strongly about the 2nd auction. We've lost our preemptive value.

I would pass in the first auction but bid 1 in the second auction (it's too important to be able to bid 2 over 2/2).

Edit, sorry, what I really mean is that in the second auction there is larger chance of a spade fit, so we have more incentive to overcall, but maybe the effect is smaller than I originally thought, in which case I would also pass.

NV? please bid 1.

That's impossible. No one can give more than one hundred percent. By definition that is the most anyone can give.

I don't really want a spade lead.
I only mildly want partner to raise to 2.
I don't want partner to bid 3.
I really don't want partner to bid 4.

I don't understand why 1 is so obvious, the upside seems very small.

I'd overcall both.

On the first, I somewhat sympathize with Roger, and I consider it close. But, I think I'll be on lead enough to make the preemption worthwhile. I could be talked out of it.

But, I'd overcall 2 on both. White on red, against great opponents. I'm tossing them an issue.

I'll overcall both, but I could be convinced to pass in the 2nd auction.

I'm an aggressive 1 level overcaller so both of these seem like an easy 1S. Come in at a low level, we could buy it in 2S, partner raising it to 3 could be a devastating effect. Don't think I can be convinced to pass on any of them, especially at this vulnerability.

1S definitely on the first. 1S also on the second, but more tentatively.

I used to overcall very aggressively on the first auction but I have been much more conservative recently when partner is a passed hand. Mostly I think I am getting better results from this approach.

In the second auction partner might have a decent hand so I am more inclined to bid. However I have a bad suit and only 9 HCP. So I am not convinced that is right.

Much depends on the opponents I think.

I'm not sxure why Roger doesn't want partner to bid 4S on the first auction. Partner didn't open but is allowed to hold 5 spades. We are white against red, I don't see the problem. Same with 3S.
and the result can be plotted on a graph.

I think there is more benefit of overcalling in the first auction than in the second auction. Partner is more likely to have a semi-useful hand with 5 spades. Bidding 1 is more preemptive. Given my hand, getting to 2 is more important over 2D than over 2H.
In any case, we are white vs red, I am really happy with any raise by partner.

On the first one I'd bid 2. Obviously, partner should know that I might have this for 2.

On the second, where partner might still have a good hand, I'd bid 1.

Can someone explain to me the principle of why they think taking action over the response is more attractive than bidding directly over the opener?

On the second auction the diamond holding is not nearly as bad and the heart holding is arguably better. Anyway I guess I overcall on both, it just seems to cause good things even when I can't think of what those things will be.
Please let me know about any questions or interest or bug reports about GIB.

When the opponents each bid, your bids are more often purely competitive. When only one opponent has bid so far, your likelihood of wanting to initiate a constructive game-seeking auction is higher.

Plus, you are more likely to have game when our strongest hand is behind theirs, and hence you are more concerned about constructive values when bidding behind their stronger hand.
