pclayton Posted January 7, 2008 Report Share Posted January 7, 2008 In our local duplicate last Friday, the other direction had an ordinary strip-squeeze for the 11th trick in a major suit contract. LHO had opened the bidding, and the count of all suits was known. Entries were not a problem. Declarer simply had to run its winners and come down to: ♠Q♥xx ♠x♥AQ LHO is known to have both Kings. You simply had to count the hand and determine if LHO bared the ♥K or not. I would consider this to be a Bridgemaster level II hand and I would expect that all of the intermediates on BBF to get this hand right at the table. Guess what percentage of the declarers got this hand right? Quote Link to comment Share on other sites More sharing options...
Trumpace Posted January 7, 2008 Report Share Posted January 7, 2008 I voted for 10%, though If we knew which area this club is in... My guess is only the pair on your table found it, so you got a bottom instead of an average. Quote Link to comment Share on other sites More sharing options...
gwnn Posted January 7, 2008 Report Share Posted January 7, 2008 there's no strip squeeze in BM level 2. the answer is obv 0%, cause it's basically impossible for everyone to get it right and it's unlikely that the number of times the contract was played is divisible by 10.

PassedOut Posted January 7, 2008 Report Share Posted January 7, 2008 I voted for 30%. When I played duplicate club games in Atlanta, there were quite a few competent dummy players. Quote Link to comment Share on other sites More sharing options...
Roupoil Posted January 8, 2008 Report Share Posted January 8, 2008 Wow, I would not expect more than 10% of the players to find it where I play. And I am pretty sure that nearly no one of the so called ADVANCED French players with whom I play on BBO would find this. But there is a big general misevaluation on BBO categories anyway...

helene_t Posted January 8, 2008 Report Share Posted January 8, 2008 I don't usually find that play myself. There is one player at the club in Amsterdam where I used to play who would probably find it, but of course the probability that he's declarer on that board is 25%. I voted 10%, although Csaba's argument is good. Quote Link to comment Share on other sites More sharing options...
Guest Jlall Posted January 8, 2008 Report Share Posted January 8, 2008 I'd go 10 % I guess, closer to 0 than 20 for me though Quote Link to comment Share on other sites More sharing options...
SoTired Posted January 8, 2008 Report Share Posted January 8, 2008 10% seems reasonable although 0% might be more likely. Experienced honeymoon bridge players get this one right because it occurs so often. :) Quote Link to comment Share on other sites More sharing options...
Finch Posted January 8, 2008 Report Share Posted January 8, 2008 At my local club I would expect somewhere between 0 and 2 pairs to find it, although some people might make 11 on some other ridiculous defence. A 'routine' strip squeeze our way is a fairly normal 90%+ board. So I agree with 10%. Read Larry Cohen's article in a recent bridge world about a 'routine' declarer play hand (I think it was an endplay, can't remember) from the Life masters pairs, and how few people took the technical line.

keylime Posted January 8, 2008 Report Share Posted January 8, 2008 Around here, I expect 1/3'rd to 2/5'ths get it right due to the quality of the field. In Baltimore, 10% is about right. Quote Link to comment Share on other sites More sharing options...
cherdano Posted January 8, 2008 Report Share Posted January 8, 2008 Phil, if any "intermediate" gets this right at the table, then she should quickly update her profile and set it to advanced. Quote Link to comment Share on other sites More sharing options...
pclayton Posted January 8, 2008 Author Report Share Posted January 8, 2008 Well, when one looks at the types of declarer play problems that gets posted on the BI, a strip squeeze feels like one of the easier types. The correct answer: ZERO percent. I would have guessed 10% myself, but the only other decent pair (they won the 0-5000 mini blues in SF) in the entire room was sitting in the other section. I was the LHO here. As I was discarding, I thought - hmmm, should I bare the ♥K? I quickly put that thought out of my mind. :rolleyes: Quote Link to comment Share on other sites More sharing options...
helene_t Posted January 8, 2008 Report Share Posted January 8, 2008 Well, when one looks at the types of declarer play problems that gets posted on the BI, a strip squeeze feels like one of the easier types. I can solve most BM 3 problems and a few BM 4 problems so of course I could solve this one in theory, but I probably wouldn't solve it at the table. There is a big difference.

I can solve most BM 3 problems and a few BM 4 problems so of course I could solve this one in theory, but I probably wouldn't solve it at the table. There is a big difference. Just want to echo this. There is a huge difference in having a bridge problem, knowing its a bridge problem, and having infinite time to think as opposed to just playing a hand that you don't know is a problem and having a set amount of time and having to focus on a bunch of other things. I would guess that a lot of the BBF advanced/experts would get some of the hands that are posted on the beginner/int forum wrong at the table some % of the time.

pclayton Posted January 8, 2008 Author Report Share Posted January 8, 2008 I wish I played as well at the table as I analyse on BBF. That's intriguing. Frequently, I'll make a rush to judgment on BBF without thinking about the hand too much, or sometimes when I post there are external distractions. When I'm at the table, there's a rhythm to the play, and hopefully not a lot to distract me besides the time clock or the director hovering, so I'd like to think I can solve problems better at the table. Of course, I don't have the luxury of a scratchpad, or RP's bridge calculators either. Quote Link to comment Share on other sites More sharing options...

kfay Posted January 8, 2008 Report Share Posted January 8, 2008 10% maximum. I don't really consider this to be BMII, though. First you have to assume that everyone is counting... which stops for the majority of people once they realize they have their 10th trick. 'If we get an overtrick... great, but I don't really care.' Second, even if they are counting there's that element of fear that they may have done so wrong and so somehow blow the contract if they try to endplay LHO. Frankly I'd be surprised if it even was 10%. Take me to a regional and give me odds and then I might go some std. deviation higher. Quote Link to comment Share on other sites More sharing options...
kfay Posted January 8, 2008 Report Share Posted January 8, 2008 Read Larry Cohen's article in a recent bridge world about a 'routine' declarer play hand (I think it was an endplay, can't remember) from the Life masters pairs, and how few people took the technical line. It was a basic strip play. It was a good article although I think that several people got it right so it was more in the 30% range here. But obviously this play is much easier than that in the OP.

y66 Posted January 13, 2008 Report Share Posted January 13, 2008 This post makes me feel like I'm pretty lucky to be playing bridge in the DC area. I'll bet there are 100+ A/X players who would get this one right at the table most of the time (yours truly most definitely not included, not A/X either). On a given Thursday night, that works out to 30+ percent of declarers in the A/X game. You guys better start working on your game if you want to do well in the summer '09 Nationals! Maybe I'll be getting these right by then too. :) I'll be trying! p.s. This is a typical BridgeMaster level 4 problem. Quote Link to comment Share on other sites More sharing options...
