Would you confirm you and my opps are decent advanced or expert players?
When we posted the hand and made some comments on it, normally it has nothing to do with the private skill.
Your main point is south must pass even with zero point hand over pd's penalty double to opp's 1nt.
To be honest, this is just a classic content only for beginner and intermediate.
You are making a rediculous joke.
Lycier, you are just out of your depth here, you have no idea what you are talking about. Look, with a long suit and weak hand, it's reasonable to run, because you have somewhere to go. On balance you think that you can make your contract playing in your long suit, or escape for a small penalty, or that the opponents will bid over you. But with a bad hand, balanced, the odds change. You aren't going to take that many more tricks playing in your long suit, because it's substantially less likely you have an 8+ fit there, and with flat hands you don't gain tricks as often with ruffing vs. just playing in NT, as compared to unbalanced hands. So *a lot* of players play that weak balanced hands you just pass and take your chances. This can pay off both when any of:
1. Partner doubled on like a 20 count and has your weak hand covered with extra HCP.
2. Partner has a good long suit and entries, bolstered by your 3 cd support (at least if you are balanced, if partner leads a long suit it's not your singleton!), and has the timing to take 7 tricks even though your side is short on points.
3. Even though the opponents make 1nt-x, the penalty of 180, 280, 380 or whatever is less than the -300/-500 you might get by running.
It loses when the above didn't happen, and partner randomly hits with 4 cd fit for your one suit, or the opps weren't going to figure out to double you, or something of that nature.
You are probably in a bad spot on average when partner doubles and you are broke, but the fact of the matter is that you aren't super likely to get to a substantially better spot by running. At least by passing, you pick up some very good boards when partner is able to beat them by himself. And you still pick up something from people who run and give up -300 instead of -180.
If you say that South must always bid when weak, then how do you propose South runs?
1. South just bids his 4cd suit, North always sits. Then you reach ridiculous 4-2 and 4-1 fits and examples like were given previously where you are in some terrible contract down several when you had a chance to beat 1nt.
2. South bids 2c on 3, North is supposed to pass/bid suits up the line. This will get you to at least a 7 card fit if South is 4333, but often still misses your 4-4 fit. And now, this really hurts you when South has 5/6/7 clubs, when you really want North to be passing on stiff/doubletons/3, now he will be bidding instead. And what if South is like weak 3442, you want to play 4-2 club fit, bid clubs? What if South is 4432?
And if you want 2d to also only show 4, then you've hurt South's ability to show 5/6/7 diamonds AND clubs.
It's simply not possible to cater to all possibilities. The opening side, the 1nt that got doubled, can cater to more possibilities since they can potentially utilize both pass and redouble, if they want to play a complicated runout system. They also have the advantage of opener always being balanced and being a narrow range so they have a better idea that they are doing a reasonable thing. The intervening side, since the double is wide ranging (doubler can be very strong, running can be a mistake), and can be unbalanced (so responder running to his own suit has no guarantee of even partial fit), is in a much worse position to be playing such systems, especially since you can't redouble partner's double!
