Paul, could you explain.

Given the actual layout, I'm not seeing how a low heart at Trick 6 doesn't yield the same result as the A. West presumably ducks the heart to East. On the spade return, discard a club while West ruffs. After the club ruff, you can ruff any return high, draw the last trump, and claim the rest for down two.

RR: Could East infer that the 5 wasn't from !QJ65 (giving Declarer A43)?

Added: I meant K43. (I had the N/S diamond honors mixed up.)

I agree that the number of combined winners in the black suits will seldom be affected by whether a defender ruffs the second round of spades. However, it seems that the analysis needs to consider the heart suit also.

If trumps are 2-2, then immediately drawing two rounds guarantees at least 12 tricks: 7 trumps, 1 diamond, 2 spades, and 2 hearts (even if the king is offside).

If Declarer instead tries to cash a second spade at Trick 3 and East is 1=2 in the blacks without the K, then only 11 tricks are available even double-dummy: 8 trumps, 1 diamond, 1 spade, and the A. Knocking out the K ceases to be useful, because this would be the second defensive trick.

Added: I said “double-dummy” in the third paragraph because taking spade ruffs while leaving an enemy trump outstanding would risk an overruff if Declarer doesn't know that the trump is with West.

If one is desperate, there's always type-correction fluid.

Page 5: “Partner appears to have an odd number of clubs, which could well be 5 clubs. If so, continuing clubs is clear, and will defeat the contract if partner has the A or KQ.”

I believe that the latter holding would allow the contract to be claimed after Declarer knocks out the A and the defenders run the clubs.

I improvise spoilers by using a font color that blends in with the background. For replies to a discussion-starter (which have a light grey background), I use font color “#EDEDED” (that is, [color=“#EDEDED”]) to make text virtually invisible. An example is below.

Spoiler: Sorry, the spoiler is on holiday.

To reveal the hidden text, position the mouse on the word “Spoiler” and triple-click. (A different method might be available or necessary, depending on the device being used to access this website.)

This article might be better placed in the Bridge Winners Site Feedback forum.

I'm curious as to why Declarer didn't draw a second round of trump before starting spades (assuming that the bridge movie is accurate).

I wouldn't have been surprised if the title had started with “Human Forum:”.

Len, I haven't calculated the percentages, but I would be surprised if my line, which caters to clubs 4=4 or K onside, was not more likely to make than a line that probably requires the K to be onside.

“You guess to ruff the 3rd spade with the 10, and then cross to dummy. You lead the Q and it goes K, A, low.”

Assuming that the fourth round of clubs is ruffed by East (West's ruffing seems less of a problem: Dummy overruffs and leads the higher remaining trump for a finesse), then after South ruffs the third round of spades with the 10 and crosses to the A, it seems better to lead the 3 toward the jack rather than leading the Q. If the J holds, cash the A (hoping trumps were 2=3). If East's K pops up on the first round, lead the 5 toward the seven, ruff a spade with the jack, lead to the Q, and cash the long spade at Trick 13.

East could trip me up by playing the K on the first round when dealt K9x, but that would be a heck of a play.

Not sure I agree with the premise that Partner holds QJ9. Holding the bulk of our assets, Partner might need to retain exit cards in diamonds for as long as possible.

Perhaps Partner has x AQ109 9xx KJ9xx. If I return a diamond (after getting in with a spade), Declarer will probably win in hand in order to cash the long spade (on which Partner pitches the 10) and lead toward the K and East's ace. Partner exits with a club to Declarer's ace. If Declarer now exits with a heart to East's queen without first extracting East's remaining diamond, East can exit with a diamond and take the last two tricks on the forced club lead from Dummy.

Public Service Announcement:

The play can be added to a hand diagram as described at https://bridgewinners.com/forums/read/bridge-winners-site-feedback/suggested-help-qa-on-how-to-add-to-hand-diagram-code/.

(I thought I'd mention this even though I had no difficulty with the text description of the play.)

I'm trying to figure out why North opted for notrump rather than spades. If South's 2N suggested 5=4=3=1 (not saying that I think it should), perhaps North felt better-prepared for the likely diamond lead than if South was showing 5=4=2=2. But as North, I would prefer spades in either case.

I would say it denies the combination of (1) minimum response, (2) doubleton in opener's first suit, and (3) tolerance for opener's second suit.

Was a negative double available to West over 2? (The answer probably won't make me want to retract my “like” of Etienne's comment, but it could be useful to know.)

I haven't followed anyone, but in light of Joe's comment, perhaps I should reconsider.

Thanks for the correction. But now I'm curious as to why Bob's play, albeit startling, was so devastating psychologically.
