How do you defend here?


Bonus questions: 1) how do you feel about passing 2?

2) Do you agree with the opening lead, if not what would you have led?

3) How about ducking the first club trick, do you agree?

Edit: In response to bd71's question, East is an unknown quantity, but in a club game or online you have to take advantage of the bad plays.

Second Edit: In response to Han's question we play UDCA, so partner probably has 4 diamonds.

I really don't know what's going on here.

Do we know anything about East? Is he a beginner? His play seems bizarre...why is he giving us a ruff in his solid diamonds? Unless partner failed to win the first trick with an honor (and why would he do that?), then RHO has KQ, and driving out A, hoping to figure out the T as you draw the rest of trump, and THEN running 4 diamond winners seems like a stand-out strategy.

East can't have much more high-card strength than what we know he holds (KQ A). Probably one more card which really shouldn't be the A (leaving partner with only 10 hcp...AKQJ...for his opener). Probably doesn't have the K or he would have led toward it from dummy while he could.

So, in my ignorance I just want to lead conservatively so as to not give him a trick, and I want to prevent him from ever getting back to dummy to use his J for a discard. I achieve these things by ruffing this and leading a . Leading could give him a trick he doesn't deserve (although it's unlikely) and/or could let him back into dummy with Q (if he holds A) to use the J.


Bonus questions...agree with all three of the actions you ask about there.

1. We can't bid 2 (forcing) and commit ourselves to 2N/3-level with what might only be 20 hcp between us. We should have 10-11 minimum to do that.
2. I think leading partner's bid suit without any other obvious options is easy.
3. Must duck in case partner can win (although unlikely because East probably wouldn't play trump this way if he's missing either KQ, or to possibly give East a guess on where T is (might he finesse on the way back with KQ9xx(x)?).

1. I feel awful. We may be defending 2C almost cold for 4S. Is partner supposed to reopen holding Axxx x KQJxx Kxx? Double isn't very attractive either but maybe it is best. Anybody else want to play that double shows 4+ spades?

2. The diamond 10 seems stand-out.

3. It's hard to see how ducking the club could be wrong, assuming that partner's 2 of diamonds was negative.

By the way, what is our count carding? Has partner shown a 3-card diamond suit?
Please note: I am interested in boring, bog standard, 2/1.

Don't mind a bit. I hope others follow your examples and post their own defensive quizes. Maybe someday we will collect the best of them along with the better answers, and post them in a PDF somewhere.

I have opinions on all three questions.

1) Not thrilled with passing 2
2) Agree with the opening lead (confused by declarer's play on diamonds, guess he doesn't have King)
3) Agree with duck first club.

I am confused by declarer's line of play, and there are questions about partners choice of signals. My views are contained in the following spoiler. Some discussion there in (about signals) is probably unsuited for beginners, but could be useful for others if they are not familiar with different concepts.

Probably true. I also considered posting the hand from partner's point of view because of what's in the following spoiler.

I was South and wasn't thrilled about passing 2 either. When we let 2 make I was particularly unhappy with my decision to pass. I'm still not sure what exactly I should bid. Double and then pull 2 to 2? This line of questioning seems to run into my other post. For some reason I never really grasped this part of competitive bidding.

Partner can't be super-shapely, so he must have a full opener. That leaves RHO with the bare minimum 2-level overcall. We already saw the diamond ace from him, he must at least one club honor (more likely the K unless he bids 2 on Q9xxx), and probably at least one heart honor (if partner's hearts are AKQJ, he'd probably have opened 1). That leaves him no room for the spade ace.
Partner has 4 diamonds, so declarer is out of diamonds. So we just lock him out of dummy: ruff with the T, cash club ace, lead spade jack. Now he can't finesse partner's heart honor(s) or cash the J.

Very nice. Just to follow up, why the Jack in particular? How do you know you haven't just blown up a spade trick when dummy covers the queen and partner wins the ace?

The J is only bad if declarer has the T but I expect partner to return a spade and I can finesse my 8. Declarer doesn't have 4 spades because otherwise partner would open 1.
What worries me more is partner having A2 of spades and declarer ducking the jack. Now I have to continue a low spade and partner can't return a spade. Hopefully he can just play a trump in that position.

You play the J instead of the K exactly because the declarer may have 10x(x). If partner has A2 of spades, probably he'll be endplayed. Not much we can do about it.

Also, I was CHO here and made a boneheaded return of a diamond. Admittedly, I was not thinking hard at this point, but my view of the hand was that partner had Jxxx/xxx/xx/AK108.

This made sense since OP didn't get in the auction, since declarer (who actually held KQxxxx) didn't continue trumps (???), and since partner led the J. All of these said to me that partner didn't have the spade king. I had visions of partner trumping my diamond return and pinning declarer in hand to possibly have to lead away from K9.

If I had given this about 1/4 second more thought, I'd have seen that if this were the position (a) we're always beating it if P has the K, so who cares, (b) declarer could just pitch a spade on the diamond thru and I'm never scoring a spade anyway, © there's a potential surrounding play that partner might be looking to exploit, so he might have led the J from KJ9x, and (d) partner can't possibly have an exit card with which to pin declarer in hand anyway.

So yeah, I goofed big time. Well done seeing the surrounding play, and sorry for punishing you for it.

edit: incidentally, my diamond spots were count (UD) then SP. Is this more-or-less normal?

South on lead. Note (actually work this out) that he must play the J to keep declarer from taking a trick in the suit. Your J and 9 "surround" declarer's 10.

Normal or not, I understood it at the time. Dunno if it's the agreement that experts (or even good) players would have in a situation, but I think that when pitching a suit that has nothing more to be said about it (except that you want to pitch it) SP is a nice default.

Certainly. He will be 2443 if he has 2c

Perfectly normal.

Dummy had KQJ9 and your partner lead the TEN, and dummy played the NINE. Now this is a very, very rare occurrence. Both North and South should realize who has the ACE. I mean gosh. So obviously, no matter how strong your agreement is for giving "attitude" at signal one, attitude is out of the question.

So your first diamond has to be either "count" or "attitude". What it is, is surely up to you. I believe here my default would also be count like your use. IF first diamond is count, then the next diamond has to be suit preference. If diamond 2 was suit preference, then second is "count" (remaining or original depending upon agreement). The question is what suit should north signal.

So the 5 would point interest to spades. How good where your hearts? Did you imagine the need of a spade lead when holding ATx of spades to avoid being endplayed in hearts? Did you have Ax of spades and looking for a ruff?

Sorry for the long delay in posting an answer. Many people already got it right, and there was even a discussion of a surrounding play. Here was the actual hand (I've left wyman in as my partner since he's already mentioned he was)




I probably should double 2 clubs, but so it goes. As you can see, it didn't matter that I led the J of spades this time, but imagine if the hand were



If I'm going to lead a spade, then I *have* to lead the Jack. (granted, partner is *way* too light for a 1 opening, but I was having trouble constructing another hand where it mattered).

Antrax is right, if dummy ducks, then partner is potentially endplayed in different situations (he may have to break hearts), but in situations where partner has to give up a heart trick and has only Ax of spades, it means he has to have a third club and we'll set it 1 trick anyways.
