The opening lead is the 2 won my RHO with the J who shifts to the Q.

5-0 spades to my left would suck, but is still managable.

I cash K of spades at trick 3, if all follow, another spade to the Q. If spades are 3-2, come to hand with a club, pull the last trump, and lead 8 of diamonds to the A, and back to the J. Essentially play RHO for some number of spades, AQJxx hearts QJ9x(x) clubs, and the diamond queen unless it pops up. Once I make the spade play I may be more inclined to drop the Qx doubleton to my left by going up. I guess I'll do this if RHO shows up with only 1 spade.

I know I suck at bridge, but I'll try this anyways. We know East had 5, and expect 5 as well. There are cases where (s)he might have 4. The most likely/relevant distributions are 4504, 3514, 3505, 2515, 1525, 0535 (not in any order). Playing up to the Q is correct, and a low spade back. Because it's the internet and I can afford to be wrong, I'll finesse the JACK on trick 4, to cater to the 4054 (in real life, I'll play for the normal break). If I only had another entry to dummy, I would play West to have Qxx.

To push this board against gib, it is very simple. Gib always assumes an opening to show 12 HCP or more. So you just play S to SQ, then finesse ST. If it lost, you just take D finesse later.

I'm going to cash the king of clubs and lead a diamond to the Ace. Does LHO follow to the diamond? I'll finesse the diamond Jack next.

Take the 2 club winners, to the Q (I assume RHO shows out), ruff a heart, cash the K and a diamond to the ace. If LHO is 5314, it won't help to ruff the diamond:
If LHO discards the heart, exit a diamond and play to endplay both opponents (the first only gains a tempo).
If LHO instead throws a club, ruff a heart and then exit in diamonds. If LHO does not ruff, then refuse to ruff whatever RHO leads next. LHO will be forced to ruff and will be endplayed in trumps. If LHO ruffs, we have simply lost 2 spades and a heart.

I am playing RHO for 5-5, if he's 5-6, oh well.

If RHO is 3550 then I can endplay west via running all my trumps but one ending with KJ84 of diamonds and the CK and a trump, opposite whatever in dummy. LHO will be down to 4 diamonds and a heart and a club. Now I cross to the DA, ruff a heart, cash a club, and exit a low diamond. I have to be careful to not let LHO have the chance to be down to 4 diamonds and 2 hearts though, so spade to the queen and ruff a heart before everything.

If RHO is 2515 or 1525 or 0535 I don't see how what I do matters much unless I have missed something.

I thought of this as well, but if LHO is 5=3=1=4, he pitches a heart on the 2nd diamond...when you exit the diamond (which is your 2nd loser) lho pitches a club, and rho simply leads a high heart....you have no answer. If you ruff low, LHO overruffs and exits his last club. If you ruff high, lho pitches and comes down to J976 in trump while you hold A108 and a diamond. Lead the diamond, he ruffs and exits a trump.

This is the idea.

There are no real issues with 2-2 or even 3-1 diamonds. If LHO has five spades, I'm not sure you can get a reliable count on diamonds anyway and decide between RHO being 0=5=3=5 and 0=5=2=6 (yes they might open this 1 unfortunately).

At the table, RHO was 3=5=0=5. In order to make the uptrick, you need to strip out LHO's hearts at some point or another. You can run your trumps as suggested above which forces LHO to abandon one, or you can ruff two hearts along the way, using your Q and A as entries.

If you don't get rid of LHO's hearts, LHO will have a heart exit at the critical time when you endplay LHO with a low diamond.

Not true - in the six card ending, we can just play off the other high club which forces LHO to give up the long heart.

What? If LHO has 2 hearts and 4 diamonds and you play off the CK, LHO just pitches a heart. Now if you cash your trump, LHO can just pitch a diamond. You must strip the hearts, and you must do so by ruffing them out, as you do not have control of the suit.

On the flip side, you control clubs, and that is an important element to this type of position. You cannot strip the clubs by ruffing, but you strip them by squeezing LHO, and having control in the suit is important. If the CK was not in tact, LHO would be in control, as he can pitch a diamond when we play the last trump and if we don't play if he can exit clubs.

Again, LHO is never forced to pitch a heart. He has plenty of safe pitches. You must ruff the hearts. My line was to ruff the hearts, including me specifically saying to be careful to remember to do so when over there with the SQ!!

I think he meant if he holds 4+2 we can still manage it in last 6 cards. (You hold KJxx+trump+K, Dummy holds Axxx+2 or whatever)

-Cash , and he has to throw a
-If he throws a go to A and ruff a and play low

EDIT: So u dont need to go to Q and ruff a just cash everything and play carefully in last 6 cards. I didnt check the whole hand, i am not sure if what i suggest is inferior if opps hold different hands, i am just talking about the original dd.

Yes, MrAce is right.

I thought it was obvious that if LHO has two hearts and pitches one on the high club that I have to ruff one more heart after playing the A.

No, I actually had this hand at the club on Tuesday Night.

Also, one further thought:

One of the really cool things about this hand is that if you don't ruff the heart right away and take it down to the six card ending of trump + high club + four diamonds - if LHO keeps two clubs and four diamonds, in order to turn the screw:

I don't know the terminolgy "in order to turn the screw" but if that means "in order to make" then you are wrong. You can simply cash your last trump before nd he has to discard, can not discard a and if discards a u cash last and then endplay him. If you meant something else, disregard what i said.

He means that the only thing you know (supose) is that he has 4 diamonds, and not how many clubs/hearts left. But you don't need to guess his distribution, you just ruff heart just in case, and the endgame will be clear anyway.
