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

 

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

Hiding answer in spoilers

 

 

Opps have 8 spades yet East denied 4 spades, so spades appear to be 5-3. This gives West at least 6* clubs and as East also doesn't have 4 hearts, West should have at least 2. This makes West 5206.

 

*Some people open 1C with 5-5 in the blacks, which would allow West to be 5305 or 5215.

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.

But, with Precision + transfers West could have the following and 1NT is a transfer to clubs.

In which case West must have 16+ HCP 'any' and East should have more than 6 clubs.

I'm going with something along these lines:

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)?

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♠

 

 

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

 

 

draw 2 trumps, ruff the 4th diamond high and only then draw the last trump and cash the remaining diamonds

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.

A deal from yesterday:

 

[hv=pc=n&sn=You&s=sk6hqj3daq8432ct6&nn=Partner&n=saj9h8djt97cakj52&d=w&v=b&b=13&a=1d2cp3nppp&a=c9]266|200[/hv]

 

Lead: ♣9

 

Your opponents' convention card: https://www.bridgebase.com/doc/gib_system_notes.php

 

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

 

Enough to play this double dummy

 

 

W opened 1♦ with 3, hence as per the cc he is 4432.

 

He doesn't have ♣Q so the only missing honours are required to give him an opening bid, hence he has Qxxx, AKxx, Kxx, 9x

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

 

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

 

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
