Defence problems: What to discard?

More tricks are probably lost due to making the wrong discard than any other reason.
It is safe to discard a club as declarer has already ruffed clubs. Instead keep length with dummy tinyurl.com/yclb727f
Normally signal with a high-ish card to encourage, but here that may waste a trick, so signal with a low card in another suit tinyurl.com/ybul6vv9 Your partner should realise you should have some high cards, switch to a heart to defeat the contract.
What should West play on the 3rd club. East discarded a low heart, so should NOT have A or K - declarer has those, so your QH should be protected! tinyurl.com/2nvwgjn2
Everyone made 3NT, but is should be defeated. What should East play on the 2nd spade? What should East discard when the clubs are played? tinyurl.com/yc833xcj

Great video-as usual! The 2S-4S hand is also tricky for another reason. Declarer loses nothing by discarding a heart from dummy since he holds 4 cards in his hand (unbeknownst to east) If East then follows along by also discarding a heart, declarer makes 4 heart tricks Tough business indeed!!

[@arunsrinivasan3732]

I thought of that too. In fact, the declarer MUST discard hearts to mislead the opp

At hand 3 (10:00) note how important it is to actually play your queen of hearts here even if you know it is going to be roughed. If you don't do that, south can play all the trumps and you can't discard your queen of hearts because it still guards the jack.

[@d95mback]

While it is true that you should keep length with dummy, if declarer discards a heart at 16:25 they make 12 tricks no matter what. They have four heart winners in the south hand if you discard a heart, and they can trump the third diamond, thus making their fourth diamond a winner should you discard a diamond.

I think it's a kind of Squeeze. If hearts are 3-2 there is no problem. If hearts are 4-1 AND the same player holds 4 diamonds he is helpless. The discard after CA shows East is out of clubs, therefore West (4xx5) has 4 red cards, and East 8 (1xx4), is our candidate for a squeeze. You discard a heart from the table, play a heart to the A (ensure there is no 5-0 break), and ruff the third diamond. Either the last diamond is high or South's fourth heart.

27:40 - i have 2 doubts here. 1. 4 h discard may also be because he has k of hearts and doesnt want it led. How right are we to assume that opp has both A and K. 2. On the contrary, if he discard 10 of spades to show he has the A of spades. He can then discard his spades without any hesitation
