Help
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?
How many got this right?

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.

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.

... and I can prove it with my usual, flawless logic.

I voted for 30%. When I played duplicate club games in Atlanta, there were quite a few competent dummy players.

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...

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.

I'd go 10 % I guess, closer to 0 than 20 for me though

10% seems reasonable although 0% might be more likely.
Experienced honeymoon bridge players get this one right because it occurs so often.

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.

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.

Phil, if any "intermediate" gets this right at the table, then she should quickly update her profile and set it to advanced.

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.

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.

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.

I think my postmortems at the table are far superior to both my play and my bbf posts

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.
