west passes at first position, and north will open, in 1 table he opened 1 in the other he opened 1 (2+, diamond 5+ or 4441), neither table reached slam, would you?

p - (1D) - Dbl
2D - 3D (2H would be NF)
3S - 4C
4D - 4H
4S - keycards

That one seems easy. Even if West misguidedly bids 2S after the double, east can just bid 3C and you get to slam.

After a 1C opening it seems tough to reach 6C.
and the result can be plotted on a graph.

I wouldn't pass as West.

1-1NT (clubs or bal / clubs inv+)
2-2 (4+ clubs, minimum / nat)
2NT-4 (balanced / natural forcing)
4-4NT (cue / RKCB)
5-6
... that would still not be conclusive proof, before someone wants to explain that to me as well as if I was a 5 year-old. - gwnn

1C - ( 1D ) - 1H
1NT -           2D! ( NMF )
2NT -           3C ( GF, shifts emphasis from Hts to Cl )
3S* -             4C! ( Minorwood in GF auction )
4S ( 2-cQ) -  5D ( = kickback for specific K's; 4NT and 5C are to play )
6C ( no K's ) -   all pass
________________________________________________________
*3S cue; denies Diam and Ht Ctrl

In the dark it looks like slam is less than 50% except for the fact that North (overcaller) probably holds all the missing K's

This is more or less the auction at the table, but East decided to bid 3NT over 3 insted of showing a not so good club on a hand that might be a missfit. It wasn't a good decision this time.
