Thanks for all the comments let me ask this differently.

If I have AQT in dummy and xxx in my hand, for 3 tricks then I had to play LHO for both KJ. So both cards being in the same opponents is clearly less than %50 probability.

In my case I need K to be in LHO and 10 to be in RHO. Aren't they both 50% probability?

According to many, Q being in the RHO is 50%/superior, why?
What if I have AT9 in my hand and KJ8 in dummy? In this case still Q being in the RHO superior?

Thank you.

True I should have mentioned that, 3 tricks. PS: BTW best for 0 trick is play King and continue the suit and discard another suit for revoke.

Yes agree, sorry for the poor word choice

What I meant was everything else is not important for this discussion

Richard, I only wanted the statistical possibilities independent from the bidding/not bidding, how many card left etc. But certainly they are important

Lol x 2

3H sounds like an easy bid.If partner bids 3NT I bid 4h. If bids 3sp I would bid 4cl.

hmm try this, copy pasted to my blog :) https://tansuaksu.blogspot.com/2018/10/to-be-deleted-later.html

i found the famous hand > https://tucson.com/entertainment/bridge-famous-hand/article_ad11a41f-06c5-5102-aa52-a3a4d17ae2b9.html

What if opener had only 2 spades? and even opener had 4sp, opponents still may get to 3h. Bidding 3 D immediately makes it harder and actually 3d makes 130, while not sure if 2sp could make 140, but doesn't matter it's a team match. Opponents had the majority of the points, whats wrong with bidding(transferring to) 3d?

This could have been avoided if NT responder bid 3CL(or any method they use) to transfer to diamond

we play 4cl special keycard asking over any weak 2 or 3, if partner gives me 1 KC, must be spades then i bid 7. i can 100% find a way to make 13 trick for ruffing d, and/or making 6 tricks in H and Clubs if doesn't have any Q

John if 3H will make them bid 4H, then they will get doubled, non-issue

if direct 4d is an invite, bidding 2d first then correcting to 4d can be used for forcing

3 H is forcing 4d should be an invite

To me Ottlik's “Adventures” is the best book, Darvas's “Ace of Diamond” story in the “Right thru the pack” is the best play, Reese and Kelsey are the best writers from the past, and i think Krzysztof Martens is a great writer should be listed as well

in real life my hand was x, AQJxx, QT98x, xx far from perfect and hoping to see no wasted values in spades..-

i always wondered why some comments are hidden, now i know
