How bad is slam anyway. On simple analysis you need the diamond finesse, then either 3-3 diamonds or the spade finesse. That feels better than 1/3 already, with extra chances like JT doubleton of diamonds, or bad leads like club queen from QJ or spade from the king. I bet it would make at least 40% of the time. Not that good but hardly awful.

At the table LHO falsecarded a lead (he was running on high tilt) from ♦JTx by leading the T. Would have been hilarious to duck this but the Q was played.

East with a diamond control will have to decide if he did enough with 2nt followed by 4♣ or not. IF he thinks 4♣ has shown extra values above the 2nt bid, and thus he has already shown his true values, he could bid 4♥. If he thinks he has undisclosed values, he could take some other call. The answer to this question might revolve around the question of rather or not 4♣ showed extras (the serious discussion already in the thread).
On the auction at the table, once west cuebids 4♠ instead of using last train (BOTH 4♦ and 4♠ shows spade control, but 4♠ shows a better hand than using last train, btw), you seem destined to bid the slam.

But, does West really have a 3H rebid ( showing 16+ hcp )?
Perhaps 3NT would better show his values ( a good 14-15 hcp , no shortness ).....
Based on "bean counting" and no shortness anywhere, East may not be so anxious to explore slam.

Admittedly it'd be easier with firmer agreements around 3S/3N/4C.

your side commited to slam, with openers 4S bid, I think opener
should not bypass 4H, he already showed add. values, and thats
it.
Of course the missing spade control may all partner may need for
slam, but if responder has enough he may bid.
This is always easier said as done.
And sometimes 30% slams make, and the slam seemed to be better.
With kind regards

Those hands are both significantly better than the original versions, and neither change makes the slam cold. We could also make slam worse by changing West's hand to AJ AKQ10xxx xx xxx.
On the original deal, both players knew that they had strength in their short suits, so if anything I think your examples suggest that one or both players overbid slightly.

On a non-club lead you would also make with the diamond wrong but everything else right.

If 4♣ was non-serious, West shouldn't have gone beyond 4♥ - that's what he'd do with a 6322 18-count. If 4♦ would have been Last Train, presumably West should have bid that, showing his spade control.
If 4♣ was serious, I think it was a slight overvaluation - it may be a 15-count, but the ♣AK10 aren't so great when they're probably opposite a 2- or 3-card suit. I think this hand is a non-serious try, then a slam drive if opener shows interest himself.

1H - 2NT!
3D!*( 15+, no shortness, modified Jac2NT)- 3S!**( Serious; says nothing about ♠-Ctrl)
3NT!( ♠-Ctrl ) - 4C ( cue )
4H ( nothing more to cue ) - PASS ( missing ♦K and either ♠ A or K and no shortness in either hand )
__________________________________________________________________________________________
A modified Jac2NT can keep the replies below 3NT which would allow "serious/non-serious" room .
* 3C! would be any minimum; 3D would then ask if any shortness;
a direct 3H/3S/3NT reply would show extras AND shortness .
** Using wyman's "Serious" from the recent 'Heart Auctions" thread: http://www.bridgebas...548#entry627548

EDIT: I'm resulting again. If Opener really had 15+ ( I actually count only 14 w/o distribution point ) , then he could easily have the ♣Q and slam is COLD .

No idea. Timo was playing this one with a non-regular partner when this hand was dealt.
Timo and I play Serious 3N. Agree that the 15 equates to a mild slam try.

Having said that, I don't dare to say that I would be able to avoid this slam with my regular partner. Opener would show a (6322) pattern with 14-16 HCP. Then responder (who has not shown anything) can invite slam in hearts or just ask keycards. It's not clear to me that an invite is best.
