You reach 3 after a crazy 2 overcall and West leads the K.

How many cards do you think West has in each suit?

4 spades looks right
seeing what card east plays on trick 1 will help you with the clubs
Sarcasm is a state of mind

My dog does bark in the night - at almost anything.

With an 8 card Spade fit, playing SAYC or 2/1 or even Acol (I think), West or East should be bidding spades.

and West leads the K.

The deal is from an ACBL Robot Duplicate (18 boards) - Matchpoints tournament I played in and the opening lead was actually not the K but the Q.

Can you place the remaininng East-West honour cards (A,K,J,Q,T,A,K)?

The consequences of this are that you play it pretty much double dummy and make 10 tricks.

It's really hard to construct a layout where West does not have a 2S bid on the second round of the auction. All the information leads to Cyberyeti's answer, but West's pass is very conservative and means E-W missed their making game.

in that case leader has QJxxx, xx, void, AKxxxxx and their partner has AKx, xxx, Q108x, xxx and they must be playing a system where that hand responds 1N rather than 1 and one where they open 1 rather than 1

So top defence beats the contract, but tough to overtake Q and return a diamond, particularly on this auction.

Even so small compensation for not bidding the cold 4

A deal from yesterday:



Lead: 9

What do you know about East-West's hands?

Playing against 2 GIB's, not much.

5 spades, 2 hearts, 2 clubs and whatever is left in diamonds
I have no idea
It looks impossible to me in 4 or 5 card majors
I'm basing it (for no reason at all) on them leading from AK

Alternatively 4 hearts, 4 spades,3 clubs, 2 diamonds and a strange lead - but then the 1NT could possibly have been 1 major
